Question

I am starting to install react native. I had successfully installed homebrew, nodejs, npm. but not able to install react native

First I had tried

npm install -g react-native-cli

gives me write warning:

Missing write access to /Users/project/.npm-packages/lib/node_modules/react-native-cli

After that I had tried

sudo npm install -g react-native-cli

/Users/project/.npm-packages/bin/react-native -> /Users/project/.npm-packages/lib/node_modules/react-native-cli/index.js
/Users/project/.npm-packages/lib
└── react-native-cli@1.0.0

Looks like install.

After that I tried

react-native init AwesomeProject

Error : react-native: command not found

What could be the problem

Answer 1

First of all, you have to install react native globally

npm install -g react-native-cli

then it will show you the path for the react native like the following

/Users/{yourUser}/.npm-packages/bin/react-native -> /Users/{yourUser}/.npm-packages/lib/node_modules/react-native-cli/index.js

Then you have to set the default path from the above result and execute the following command

export PATH="/Users/{yourUser}/.npm-packages/bin/:$PATH"

Then reload you session/env vairables

source ~/.bash_profile

It will work like charm!

Answer 2

Make sure that /usr/local/share/npm/bin is in your PATH to use binaries installed with npm

Add the following line to your ~/.bashrc

export PATH="/usr/local/share/npm/bin:$PATH"

Then reload your shell session and try that again

Answer 3

sudo yarn global add expo-cli

sudo yarn global add react-native-cli

You must use sudo here.
