“exp: command not found” How do I add expo cli to path?

问题

I installed the expo cli with

npm i -g exp

then I run

exp

and I get

-bash: exp: command not found

I'm guessing I didn't add exp to path. So how do I do this properly? Nothing I've tried so far works.

回答1:

This suggested 3 steps solution worked for me:

1. First check if ~/.npm-global/bin is in your path: echo $PATH. If it isn’t there, you will need to add it to the path.

2. Open up ~/.bash_profile then add the following line to the bottom: export PATH=$PATH:~/.npm-global/bin

3. Finally, back in the shell, type: source ~/.bash_profile

Hopefully that will have fixed your problem.

I also had a hard time getting expo command to work on Mac. Here are the steps I took to get it working.

npm root -g shows the directory the global modules are installed in:

/usr/local/Cellar/node/11.7.0/lib/node_modules

That directory might be different for you. After confirming expo is in there, edit ~/.bash_profile and add the line:

export PATH=$PATH:/usr/local/Cellar/node/11.7.0/bin

Save & exit, then run source ~/.bash_profile

Now the expo command should function as intended.

1. Find the path where expo is globally installed by npm:

npm bin -g

2. Add path from Step 1 to paths file:

sudo vi etc/paths

3. Restart the Terminal

回答4:

exp was replaced with expo

To install Expo CLI, just run npm install -g expo-cli (or yarn global add expo-cli, whichever you prefer).

回答5:

You should try npx expo init Your-App to test.

It worked for me.

Following on this issue, I found I had multiple global folders so I started using a .npm-global folder as shown here: https://docs.npmjs.com/getting-started/fixing-npm-permissions

And now it's all clean and in control.

I have found the solution. Here is the solution for react-native cli. Replace react-native with expo (exp).

I had a similar issue.

-bash: expo: command not found

It turns out the command to install expo npm install -g expo-cli was referencing an older version of node on my machine; when checked using npm root -g.

So I had to uninstall nvm/node, deleted any remnant folders & files of .nvm and shortcuts for nvm in /usr/local. Then reinstalled node and ran npm install -g expo-cli again.

That fixed my issue.

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