“-bash: expo: command not found” 安装 expo-cli 后

Question

I've just installed expo-cli with npm install -g expo-cli , but if I try and run an expo command, I just get the error -bash: expo: command not found . I've tried uninstalling and reinstalling expo-cli, and changing my.profile and.bash_profile to add the path to the global node_modules directory, but I just can't get expo commands working. Any idea why?

Answer 1

1st I enabled the finder to show hidden files by writing following commands:

defaults write com.apple.finder AppleShowAllFiles TRUE 
killall Finder

Then I searched for the expo files under my user:

macintoch HD>Users>MyUserName>

I found the expo file under the following folder:

~/Users/MyUserName/.npm-globalHomebrew/bin

Then I added the folder in the Path by executing the following commands:

export PATH=$PATH:~/.npm-globalHomebrew/bin

I checked if it is added successfully by typing the following command:

 echo $PATH

Run then the following commands to login to expo:

 expo login
 expo whoami

Answer 2

For any expo command, try running:

$ npx expo <your command(s) here>

Using the command above solved the -bash: expo: command not found error for me.

( $ denotes the terminal prompt)

I also ran npm install -g expo-cli before running my command above.

Answer 3

Use this

sudo npm install --unsafe-perm -g expo-cli
