The issue I have is that npm start cannot start. I tried to fix with audit, deleted node_dependency directory and re-installed with npm, nothing works.
One concrete issue I see is:
The react-scripts package provided by Create React App requires a dependency:
"webpack": "4.44.2"
Yet, I also see npm -v webpack -> 6.14.14. How do I need to debug this?
Your npm -v webpack command is not correct. it will return npm version and not the webpack version.
Try npm ls webpack . you can also check your package.json file for the packages you have. or run npm ls for the full list.
make sure to install the required dependency as it states.
Eventually I could not solve the package problem with an informed debugging.
What I did was to (npm install --global yarn) and start the application through it (yarn start). It worked a lot to download the packages and eventually started the application.
So, I guess I need to switch to yarn after this point, which is ok, as long as it works :)
I'm Unable to execute the expo start command.

Change expo version from "^1.0.0" to "~41.0.1" (package.json)
npm install
npm start
if anyone is still facing issues, run
yarn add expo
if you don't have yarn installed on your computer then run
npm install -g yarn
and then run the first command.
I also received your message when installing the commands in the "React Navigation" set-up instructions and fixing vulnerabilities. The problem arises when using the command: npm audit fix --force. If you check the warnings after this command, you get
npm WARN audit Updating expo to 1.0.0, which is a SemVer major change.
So, try running: sudo expo update
If that doesn't work, try installing expo again with: npm install --global expo-cli and then update.
I'm also facing this error. So I run the npm command in the terminal.
npm install
You do not need to change the expo version. you just reinstall it.
Update the Expo to the latest version sudo expo update
Then install the updated npm packages npm install
Fix the issues in the packages npm audit fix --force
Run the Application npm start or expo start
Error ? you are trying to launch the expo framework yet it can't be found installed as part of your application modules
solution? simply find the latest version of Expo i.e for my case "expo": "^44.0.0", then go to your package.json file in your root folder, under the "dependencies" property plug-in that Expo version i.e
"dependencies":{
"expo": "^44.0.0",
}
close package.json file, then in your root folder run the command: npm install
after package installation is done run expo start
I simply used the expo update command.
It asked me
You are currently using SDK 1.0.0. Would you like to update to the
latest version, 44.0.0?
and I said yes, y not..
Every Thing was good to go with the npm start command
Cheers..
See the expo version - default "^1.0.0" , change ==> "expo": "~41.0.1"
Change expo to version "~43.0.0" in package.json
run npm audit fix --force in node_modules directory
here are my 2 cents. This worked for me :
Download latest version of nodejs - https://nodejs.org/en/download/
After installing nodejs reboot your computer
install : npm install --global expo-cli
Generate a new project with - npx expo-cli init projectName
cd projectName
npm start
you can run the below to install all dependencies
npm i
or to install exp
npm i -g expo-cli
This problem I faced was because of cloning a new project and trying to run it.
Always install the modules using the below command
I solved this by
npm install or npm i
I had same problem.
I simply used the expo update command.

thats all
Is possible that you need an update try this command:
sudo expo update
Please try this
npm install --save expo --legacy-peer-deps
no need to edit package.json if expo version is not 1.0.0
You should register first on expo and then login
I had the same issue but after I logged in it was solved.
here is all about : https://docs.expo.dev/get-started/installation/
In my case, I clonned a Github repository and then used create-expo-app inside the repository directory. So, the command created a directory with the name of the app, but I was not in it: I was running the expo run command in the wrong directory.
Double check that the package.json is in the same directory in which you are running yarn or expo run to avoid this simple mistake.
The same error happened to me. But none of the other answers helped me. In my situation, I have node.js v18.12.1 installed. But when I check with nvm ls, the arrow points to "system", and on my system Xubuntu 22.04, the nodejs version installed is v12.22.9. So I needed to do nvm use 18, then
yarn add expo
expo start
Problem solved!
for window users
just type expo update into your terminal,
I'm trying to install vue-chart.js but unable to install. I tried by reinstalling npm and deleting package-lock.json file but doesnot work. I tried other methods as well but couldnot get succeed.
Please help me.
You must install the dependencies given in error. Listed below:
eslint#^5.0.0
For global install, use
npm install -g eslint
or For developement installation
npm install eslint --save-dev
Refer: https://www.npmjs.com/package/eslint
After deleting node modules and reinstalling npm solved my issue.
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
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.
