npm install -g karma does not install executable

Question

I have what looks like successful karma installation, yet karma is not in /usr/local/bin/ and is not found by bash.

Any idea what is wrong and how to fix it?

Here are the end installation messages:

> (node-gyp rebuild 2> builderror.log) || (exit 0)

Answer 1

You can link it by yourself. As in:

#Assuming that /usr/local/bin is in your PATH
cd /usr/local/bin
ln -s /usr/local/lib/node_modules/karma/bin/karma

Clearly, this is not an ideal solution. I think there's a problem in the package.json of karma which prevents npm to create a link to the executable. Might be related to this.

Answer 2

It seems that npm places all installed binaries in the folder <npm-global-prefix>/bin, so to make these binaries available in the shell you can add the following line to your shell startup script (e.g. ~/.profile, ~/.bash_profile, ~/.bash_aliases):

export PATH=`npm prefix -g`/bin:$PATH
