For some reason the Expo team is not updating their packages on npm and I need to install directly from their Github repo. The packages are in the packages/package-name folders on the main Expo repository.
I put "expo-blur": "expo/expo packages/expo-blur" in package.json, but that also just uses the npm release. I asked a similar question here: https://forums.expo.io/t/recommended-way-for-using-expo-packages-straight-from-github/22022.
What do I need to put in package.json so that it uses the code from here: https://github.com/expo/expo/tree/master/packages/expo-blur ?
No you can't. You will end up having it undefined in your package.json file like this:
The command was:
npm install Teknasyon-Teknoloji/desk360-react-native-sdk#1.0.0 --save
I tried:
npx expo install Teknasyon-Teknoloji/desk360-react-native-sdk#1.0.0
So the correct way is:
Switch to bare workflow if you are in managed workflow:
npx expo prebuild
Then follow the rest of the steps from the package docs. So I then ran:
npm install Teknasyon-Teknoloji/desk360-react-native-sdk#1.0.0 --save
then cd ios, pod install ...etc.

I have a question regarding the package manager npm and the meaning of installing the package globally.
For example I work often with react, should I install react globally?
npm install -g react react-dom
Does this mean that next time when I do
npx creat-react-app my-app
It will get the package from the global or it does not matter and it will still download it locally inside my-app?
Because I really do not understand the idea behind installing globally.
Because if I want to use a package it should be mentioned in package.json, if it is in package.json it is then located in node_module ... so yeah ...
Could anyone give me better insight?
Thanks in advance
React library can be installed globally on your local machine. In development there is no real reason to do that since you might not have the latest version and this might cause issues.
Better practise is to use react on project level by using the command you stated above npx create-react-app my-app
If you push code to a server the package.json file will install the dependencies (React, React DOM,..) to build your project.
Read more here : https://create-react-app.dev/docs/getting-started/
If you've previously installed create-react-app globally via npm
install -g create-react-app, we recommend you uninstall the package
using npm uninstall -g create-react-app or yarn global remove
create-react-app to ensure that npx always uses the latest version.
You can check what packages are installed globally using:
npm list -g --depth 0
I am using react native and Expo. I am unable to build new app because after I use expo init appName it shows the following error.
Heres the full message:
📦 Using npm to install packages. You can pass --yarn to use Yarn instead.
√ Downloaded and extracted project files.
× Something when wrong installing JavaScript dependencies. Check your npm logs. Continuing to initialize the app.
✅ Your project is ready!
To run your project, navigate to the directory and run one of the following npm commands.
- cd Scanner
- npm start # you can open iOS, Android, or web from here, or run them directly with the commands below.
- npm run android
- npm run ios # requires an iOS device or macOS for access to an iOS simulator
- npm run web
I tried multiple times to create a blank project, also tried npm install to install failed/not downloaded libraries and continue after failure but it showed another error:
npm ERR! code Z_BUF_ERROR
npm ERR! errno -5
npm ERR! zlib: unexpected end of file
also tried npm cache verify that showed cache is ok Content verified: 3562 (252580364 bytes).
So, How can I solve this issue?
Problems related to npm installation are very common If you do any mistake in early installation, but is avoided. Learn more about npm tree.
Steps worked for me are :
npm cache clean --force
npm cache verify
npm -g uninstall expo-cli --save
npm install expo-cli --global
expo init app-name
cd app-name
npm start
Always run as administrator if working on Windows and in root directory.
The solutions above didn't work for me but if you use 'npm install' in the directory of the app you get a clue that you shuold try 'npm install --force'
err message
You should have all these files folders and files at the start of the project otherwise not all the dependencies have been installed which is why we were getting the problem.folder structure
After you have added --force to npm install you have all the dependencies installed. Now you can run the app with npm start.
Unfortunately, all the solutions described above didn't work on my machine...
Here is my latest solution for this problem...
This worked 100% on my machine...
Use npm i -g expo-cli
This will automatically add the required packages and also remove the unnecessary ones.
Yes, surely, you don't need to uninstall and re-install it again.
Just follow my steps.
And, you can create your expo project using expo init.
I hope my solution will help you out from this annoying problem....
I just did npm install and it worked for me, but I had do that every time I create a new expo project.
I also encountered this problem, and finally found that it was the problem of react native cli，I installed the latest version of react native cli，Expo is back to normal
This Error is regarding to the git account. expos need a git account to setup react native project
If you are using windows you need to install git in your local PC
after that open your Terminal and type this command
git config --global user.name "your_username"
git config --global user.email "your_email_address#example.com"
after that clone any github project to your local computer. it will ask to login to Github
after all these steps try expo init <projectname>
The simple way to settle that error is by using "expo-cli init app-name" instead of "expo init app-name".
I tried and worked perfectly for me. Hope it will help you guys.
i have faced a similar problem and running yarn set version 1.22.1 fix it
Run the Command Prompt as an administrator. And run the following command:
npx create-expo-app AwesomeProject
When creating an react native app with expo, expo installs many module that i don't need. Is there a way to remove these unwanted modules like barcode reader google sign in and google maps.
thanks
To remove a package from your node_modules directory, on the command line, use the uninstall command. Include the scope of the package is scoped.
Unscoped package
npm uninstall --save <package_name>
Scoped package
npm uninstall --save <#scope/package_name>
if need to know more about it then follow official Document here https://docs.npmjs.com/uninstalling-packages-and-dependencies#removing-a-local-package-from-the-packagejson-dependencies
npm uninstall <package name> works. It removes the expo module from your node_modules
for more reference

With NPM
$ npm uninstall jest
Shorthand version
$ npm r jest
With Yarn
$ yarn remove jest
I am new to react-native and I want to install react-native-maps. However whenever I run npm install react-native-maps --save in the project folder, the project breaks with node_modules/react-native become empty with only an empty folder node_modules inside. I am following the installation guide from the official github now and using react-native 0.55.3.
Below attached with a dump when I call npm install react-native-maps --save:
screen_dump: react-native-maps install failure:
There is a known issue which is fixed with v5.7.0 (As far as I know. Didn't try it myself).
After updating your npm to a newer version, you should delete node_modules and do a clean install with npm install to reinstall all necessary packages.
One other option is to use yarn. I think it is a little better tool for package management. (Personal preference. You don't have to use it). If you decide to use yarn, you should still delete node_modules and do a clean install with yarn install
Install yarn package manager from the following link
enter link description here
Use following command to install the package.
yarn add react-native-maps
This might be works. Yarn packager is better than npm for me.
I have installed a third party library in my project but it is not working , so I want to delete that library from my project ,
How can I do that ?
If it is a library based only on javascript, than you can just run npm uninstall --save package_name or npm uninstall --save-dev package_name
If you've installed a library with native content that requires linking, and you've linked it with rnpm then you can do: rnpm unlink package_name then follow step 1
If you've installed a library with native content manually, then just undo all the steps you took to add the library in the first place. Then follow step 1.
note rnpm as is deprecated
I followed the following steps:--
react-native unlink <lib name> -- this command has done the unlinking of the library from both platforms.
react-native uninstall <lib name> -- this has uninstalled the library from the node modules and its dependencies
Manually removed the library name from package.json -- somehow the --save command was not working for me to remove the library declaration from package.json.
After this I have manually deleted the empty react-native library from the node_modules folder
If you want to unlink already installed packages in react native
$ react-native unlink package_name
$ yarn remove package_name (if it is npm then npm uninstall --save)
If you execute 2nd step before 1st step you need to install relevant package back and execute 2nd step
I will post my answer here since it's the first result in google's search
1) react-native unlink <Module Name>
2) npm unlink <Module Name>
3) npm uninstall --save <Module name
From react-native --help
uninstall [options] uninstall and unlink native dependencies
Ex:
react-native uninstall react-native-vector-icons
It will uninstall and unlink its dependencies.
You can delete installed react native package with this command.
npm uninstall package_name
example:
npm uninstall react-native-camera
remove package name from package.json file
delete package-lock.json file
then run npm install
or you can run the following command to uninstall any package
npm uninstall package_name
you have to check your linked project, in the new version of RN, don't need to link if you linked it cause a problem,
I Fixed the problem by unlinked manually the dependency that I linked and re-run.
For iOS...
Remove the node package and install the pods.
If you're using npm:
npm uninstall package-name
If you're using yarn:
yarn remove package-name
Then simply install pods with:
npx pod-install
Typically the package.json directory is in the root of your project folder, so you should run these from there. npx pod-install will go to your ios folder and will run pod install. You do not need to run this step if you are not adding/removing native components.
I think for Android it might be the same steps, but without running the latter command since Android does not use cocoapods.
Simple and easy solution.
npm uninstall --save react-native-image-slider-box
All of the top answers are a bit outdated. They do work, but the process could be better. So I'm going to post a more modern and 'normal' way.
Assumptions:
Your project is not overly old, meaning that your project is not using react-native version <0.60 (less than 0.60). This is because in the past (when you had react-native version <0.60), you had to manually run commands like react-native unlink when you wanted to uninstall a package. Those commands still work but are no longer necessary.
The library/package works with autolinking or it doesn't need linking at all because the package doesn't use native code. If the package's installation instructions don't require you to run a command to link the package (e.g. react-native link), then it uses autolinking or it doesn't need linking at all. A package might suggest you run the link command but they'll also usually say it's not required if your project's react-native is version >=0.60. The majority of libraries are like this now. I'd be surprised if the package you want to uninstall uses native code but doesn't support autolinking. Read more about autolinking.
If the package you want to uninstall doesn't use native code, then the above paragraph about autolinking doesn't matter.
You of course remembered to remove any use of the package in your project, before you try to uninstall it.
You've checked if other packages require the package you want to delete as a peer dependency. In this case, you removing that dependency can cause your other packages to not work.
If your package was installed without any manual editing of native files (e.g. android/settings.gradle, ios/yourappname/AppDelegate.m, etc.) or any other configuration (e.g. mypackage.config.js), then you should just do this:
If using npm, run npm uninstall <yourpackage>. If using yarn, run yarn remove <yourpackage>.
(React native uses autolinking to unlink the packages automatically so this is all you should need to do to 'unlink'. Read more.)
Run cd ios && pod install && cd ..
You can skip this step if you're absolutely sure that the package is purely written in JavaScript/Typescript. My opinion is to just run it anyway so that way your brain doesn't have to spend energy thinking/worrying about this.
That's it. You're good to go. If you're not good to go here, then something is very wrong.
If you did have to manually edit native files or any other extra configuration to install your package, then:
It's a good idea to get all the info you can on what you exactly did when you installed the package. Any additional context you can learn is good.
You should look at your git history to see the changes you did when you installed the package.
It's a good idea to read the package's README or docs to remind you of anything else you might have forgotten.
In addition to the package's most up-to-date README or docs, it's a good idea to try to read the package's README/docs from the exact version that you're trying to uninstall. If you just read the README from the package's main github page, for example, then the info might be too new.
Undo the manual changes you did when installing the package. Ideally, use git diff or a git GUI program to help you out with this. Because this process varies depending on the package and what you actually did, it's hard to be more specific than that.
If using npm, run npm uninstall <yourpackage>. If using yarn, run yarn remove <yourpackage>.
