No command 'ember' found

问题

Seems like I messed up with my ember-cli install. I had installed the npm using sudo, but after reading some issues with ember-cli and sudo on npm I went for uninstall and reinstall following the instruction here https://gist.github.com/isaacs/579814.

Now I have installed ember-cli through npm install -g ember-cli but when I do an ember new <name> I get

No command 'ember' found, did you mean:

Command 'enber' from package 'asn1c' (universe)

ember: command not found

I can do which node

$ which node

/home/[user]/local/bin/node

and which npm

$ which npm

/home/[user]/local/bin/npm

, but I can see that ember exists in the following path that is installed:

npm install -g ember-cli

/home/[user]/npm/bin/ember -> /home/[user]/npm/lib/node_modules/ember-cli/bin/ember

Any ideas how to get ember command working?

You need to make sure /home/[user]/npm/bin is in your shell's path. You can echo $PATH to see if it's included.

For Bash:

Add this to your .bashrc or .bash_profile

PATH=/home/[user]/npm/bin:$PATH

And then restart your terminal or run source ~/.bashrc

For ZSH:

Add this to your '.zshrc`

path+=('/home/[user]/npm/bin')

And then restart your terminal or run source ~/.zshrc

You will need to replace [user] in the paths with your user name on your computer.

Another approach is to use nvm. It gives you power to easily manage your node.js/npm versions without sudo and also manage installed packages. One drawback (or maybe not?) is that you have to install packages for each node version separately.

The accepted answer works. Where I disagree is with using ~/.bashrc or ~/.bash_profile. ~/.bashrc is used for only non-login shells and ~/.bash_profile is used for login shells.

I advise you export to $PATH in ~/.profile which will be available to the whole desktop session.

Therefore, you should add something like
