-bash: react-native: command not found

问题:

I have successfully installed brew, node 4.0+, watchman and flow, and I received the following when I do npm install -g react-native-cli:

/Users/home/.node/bin/react-native -> /Users/home/.node/lib/node_modules/react-native-cli/index.js
react-native-cli@0.1.5 /Users/home/.node/lib/node_modules/react-native-cli
           └── prompt@0.2.14 (revalidator@0.1.8, pkginfo@0.3.1, read@1.0.7, winston@0.8.3, utile@0.2.1)

So I assume react-native-cli has been successfully installed as well. However when I run react-native, it says:

-bash: react-native: command not found

My node version is 4.2.1, watchman 3.9, brew 0.9.5 (git 7ed6) and npm 2.14.7

You have to make sure /usr/local/share/npm/bin is in your PATH to use binaries installed with npm.

Add the following to your ~/.bashrc:

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

And reload your shell session.

If you find you don’t have a /usr/local/share/npm/bin directory, your npm may install its packages in another location. In this case you have to use the right path in the line above.

One solution to find that path is to run:

npm list -g | head -n 1

This gives you the path where npm install its packages. This is not the path you want but it’s close. For example on my Linux it gives /home/baptiste/.linuxbrew/lib; it suffices to replace lib with bin to get the correct path:

export PATH="/home/baptiste/.linuxbrew/bin:$PATH"

I tried many ways to work out a solution to this on my mac(node -v: v8.1.3, npm -v: 5.0.3). And when I ran npm install -g react-native-cli, the output was this:

/Users/xxx/.npm-packages/bin/react-native -> /Users/xxx/.npm-packages/lib/node_modules/react-native-cli/index.js + react-native-cli@2.0.1 updated 1 package in 2.988s

As you can see react-native was install in /Users/xxx/.npm-packages/bin/, different from what others may say. So I pasted the line export PATH=/Users/xxx/.npm-packages/bin:$PATH to my ~/.profile and opened a new Terminal window to run react-native. It worked!

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"

or

export PATH="$HOME/.npm-packages/bin:$PATH"

Then reload you session/env vairables

source ~/.bash_profile

It works for me .... cheers

thanks

It's easy!

Just run npm i -g react-native-cli then restart your cmd.

回答5:

export PATH="$HOME/.npm-packages/bin:$PATH" worked for me however, I had to replace packages with what was on my mac.

i.e .npm-global instead of .npm-packages. ..

Step 1 .

terminal fire : npm install -g react-native-cli output: /usr/local/Cellar/node/6.1.0/libexec/npm/bin/react-native ->/usr/local/Cellar/node/6.1.0/libexec/npm/lib/node_modules/react-native-cli/index.js/usr/local/Cellar/node/6.1.0/libexec/npm/lib └── react-native-cli@0.2.0

Step 1 .

terminal fire : npm install -g react-native-cli

output: 

/usr/local/Cellar/node/13.3.0/bin/react-native -> /usr/local/Cellar/node/13.3.0/lib/node_modules/react-native-cli/index.js
+ react-native-cli@2.0.1
updated 1 package in 4.544s

Step 2: export the path

  export PATH="/usr/local/Cellar/node/13.3.0/bin:$PATH"
