Note to future self: how I got Karma running from bash in Windows.

Yesterday, I spent quite a bit of time getting Karma to run from bash on my Windows 7 (x64) laptop. Since, a month from now, I'll have absolutely no recollection of how I achieved this, I'm writing it down here for the benefit of my future self, as well as any other people who may find this valuable.

Add karma to PATH

My first problem was that 'karma' wasn't a recognized command. Although I'd used Chocolatey to install node.js, used npm to install Karma, and 'karma' was a recognized command from PowerShell, bash didn't recognize it. While I don't yet know if the following is the 100 % correct solution, I managed to make bash recognize karma by adding my karma directory to my bash path:

PATH=$PATH:~/appdata/roaming/npm/node_modules/karma/bin

This works in the session itself, but will be forgotten by bash unless you add it to ~/.bash_profile. BTW, that file doesn't exist by default in a new Git Bash installation on Windows, so you'll have to add it yourself.

Chrome path

My next problem was that, while karma could be found, I got the error message that it couldn't find Chrome, and that I should set the CHROME_BIN environment variable. After much experimentation, I managed to make it work by setting:

CHROME_BIN=/c/Program\ Files\ \(x86\)/Google/Chrome/Application/chrome.exe
export CHROME_BIN

That looks really simple, so why did I waste so much time shaving that yak? Well, setting the environment variable was one thing, but it didn't work before I also figured out to export it.

Once again, I added these lines to my .bash_profile file. Now I can run Karma from bash on Windows.
