npm install -g karma does not install executable

问题:

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)

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.
