Tools: Not able to run wct on Windows 7

[rasto68]

From the polymer groups thread here:

Essentially wct appears to hang when running on windows 7, I can see it looking for non-installed browsers (phantom, opera) even though I specified (both on the command line and via wct.conf.json) that it should only use chrome and firefox.

Workaround is to set the LAUNCHPAD_BROWSERS environment variable to match the browsers to be used.

Copying the summary from the thread:

I'm not able to run wct on Windows 7, if I type:

wct -l chrome --verbose

then it hangs after the 'hook: configure' message and in the windows task manager I can see that it is looping around trying to find opera.exe, phantom.exe and nw.exe

After a fair amount of hacking around inside the wct code I found that if I removed the opera, phantom and nw sections from the launchpad/windows.js file then wct would start successfully. It looks to me as if launchpad doesn't handle the absence of certain browsers particularly well (or even at all) on windows. I'm still not sure why it is even looking for the other browsers given that I specified chrome only.

For me the the command shows the "hook: configure" debug output for 53 seconds before it continues. I use Windows 10 64-bit and the shop demo with the command polymer test --verbose. I have Chrome, Firefox and Internet Explorer installed.

If anyone comes across this issue (I encountered it in polymer), setting the environment variable LAUNCHPAD_BROWSERS did the trick for me. The first time it runs it needs to install all the deps. Run with --verbose to see progress more clearly.
