Karma from bash on Windows by Mark Seemann
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.
