I need to install lodash.filter to my Expo (React Native) project.
How should I do it using npm?
1.
npm i -g npm
npm i --save lodash.filter
npm i --save lodash.filter
I do not understand what npm i -g npm (it's updating something, but I think it will destroy my project).
$ npm i -g npm
$ npm i --save lodash
you can use second command.
npm i is the alias for the npm install and -g means gloabal
The -g or --global argument will cause npm to install the package globally rather than locally
npm install (in package directory, no arguments):
Install the dependencies in the local node_modules folder.
Just follow the command that are written in documentation it will be fine
The --save option instructed NPM to include the package inside of the dependencies section of your package.json automatically, thus saving you an additional step.
I have installed Expo CLI globally and cant start a new react native app without using expo cli and therefore would like to uninstall it from my system. I have spent hours trying to work out how to removeit globally from my system
To completely uninstall expo cli
On Windows
The first step npm -g uninstall expo-cli --save (also yarn global remove expo-cli if you use yarn).
Second cd %USERPROFILE% && rmdir /Q /S .expo
On Mac OS Catalina
The first step npm -g uninstall expo-cli --save (also yarn global remove expo-cli if you use yarn).
Second cd ~ && rm -rf .expo

npm -g uninstall expo-cli --save did not work for me, but yarn global remove expo-cli did.
I expected the npm option to work, and was surprised when it didn't. I am using nvm, and wonder if this answer explains why the npm option didn't work for me.
I had the same problem and after searching I found this command:
npm -g uninstall expo-cli --save
finally expo-cli is deleted from my pc but it still asks about it every time I type create-react-native-app. if anybody knows how to go on from here be my guest.
and I hope this helps you
edit: if you use react-native init it is almost the same as create-react-native-app without expo-cli. This is how I chose to carry on as using the create command with expo-cli gives the application error after error if you install any api.
if you are using npm then this command will work for uninstalling expo cli
npm -g uninstall expo-cli --save
I had the same problem once, i have tried
npm -g uninstall expo-cli
but after the my problem didn't get solved, i have searched lot even after that problem did't get solved,
i am also using yarn so finally i have decided to remove using the yarn
i tried
yarn global remove expo-cli
This indeed solved my issue
If you are using nvm.
search for node version with expo installed.
find ~/.nvm -name "*expo*" -type d
nvm use {nodeversion}
npm -g uninstall expo-cli
If yarn don't work for you or you prefer using npm use:
npm rm -g expo cli
Very simple to uninstall a npm package.
Just enter this command :
npm uninstall -g expo-cli
In Windows 10 npm uninstall -g expo-cli --save worked for me from nodejs console, opening it as administrator
In windows 10 to uninstall :
npm uninstall -g expo-cli --save
yarn remove global expo-cli
Worked for me.
After that, for install last version then:
npm install -g expo-cli --save
expo-cli --version
3.21.13
I had this issue.
My steps
npm cache clean --force
npx install create-react-native-app
cd
npm install -g expo-cli
expo start
If you get error at 4 about node.js just install latest version. Then
Open your package.json file and add:
"react-navigation": "git://github.com/Snailapp/react-navigation.git#2.18.5"
npm install
Ok, in addition to existing answers, with commands like npm -g uninstall expo-cli and deleting manually .expo folder inside %USER% i try expo whoami, and my output was:
$ expo whoami
There is a new version of expo-cli available (4.13.0).
You are currently using expo-cli 3.23.3
Install expo-cli globally using the package manager of your choice;
for example: npm install -g expo-cli to get the latest version
[13:13:03] › Not logged in, run expo login to authenticate
So i had to do a bit more manual work:
%USER%\AppData\local and deleted expo folder
went to %USER%\AppData\Roaming\npm folder and manually deleted expo related files
After that i did expo whoami and output is:
$ expo whoami
bash: /c/Users/User/AppData/Roaming/npm/expo: No such file or directory
Finally, i opened new command prompt and did npm i --g expo-cli and after installation with expo -V i get 4.13.0.
I had the same issue
i unistalled using
npm uninstall expo-cli
or
npm unistall -g expo-cli
Upon reinstalling Windows 10 (and Node.js), the gulp command isn't found. I ran it from my root folder containing package.json and the node_modules folder. I tried npm install gulp, and also npm install: gulp command still not found. I'm a bit puzzled.
Any idea?
do you re install node and npm again? when you re install node try with npm install -g gulp
npm install -g gulp will install gulp globally, so that you can use it as a command.
A better way to do it, is to use npm install gulp (without the -g) to install it into each local project, and fire it off using npm start scripts in each project's package.json.
What is the difference between npm -g(global) install and npm --save?
First gulp install -g and --save first, then for other projects:
npm i gulp --save-dev Can I just use this command?
I don't know the basic difference between them?
npm -g will install packages globally (to npm cached folder), normally in AppData\Roaming\npm\node_modules if you're using Windows, while npm --save or --save-dev will install package directly to your node_modules directory in your project and add package to your packages.json for later purpose.
I am trying to install react-native-version-number. The instructions state that after installing, issue;
react-native link react-native-version-number
but when I do this, I get the following error message;
Looks like you installed react-native globally, maybe you meant react-native-cli?
To fix the issue, run:
npm uninstall -g react-native
npm install -g react-native-cli
but when I run
npm uninstall -g react-native
I get
npm WARN uninstall not installed in /usr/local/lib/node_modules: "react-native"
How do I link react-native-version-number?
As a workaround, dv3's comment about using rnpm link did work. However, I found that I was having this problem with other react-native commands, such as react-native run-android. This appears to be because npm was installed using homebrew. A description of this problem and how to fix it can be found at on this gist. In summary the required fix is to uninstall all your npm globably installed packages, uninstall node, then reinstall node, and reinstall npm without brew.
npm list -g --depth=0 # to list all your globally installed packages
rm -rf /usr/local/lib/node_modules
brew uninstall node
brew install node --without-npm
echo prefix=~/.npm-packages >> ~/.npmrc
curl -L https://www.npmjs.com/install.sh | sh
and then, you have to reinstall all your npm packages that were installed globally.
