Failed to install extension

[roblourens]

I tried to install an extension (zignd.html-css-class-completion) and got this error. It worked the second time.

Maybe this is just a weird fluke but in case it's helpful at all, here's a stack...

It's a timing issue and hard to repro. Please try installing above extension multiple times and make sure you do not see this error.

@sandy081 I don't think that would repro this case, because you added mechanism to not really delete an extension for uninstall, so you can bring it back instantly when reinstalling. Correct?

[octref]

Anyway I ran rm -rf for the extension and reinstalled successfully for a few times.

@octref This is nothing to do with removing the extension from disk or not. Its purely a communication timing issue between renderer and shared process. I can explain to you if wanted.

But I think your way of verification is also sufficient.
