Installing from the command line or UI does not work

[rgl]

I'm trying to install from the command line with:

code --install-extension ms-vscode.PowerShell

But after I start code it errors out with:

Even reinstalling the extension from the UI does not work.

Sorry, but I didn't find a way to troubleshoot the install (--verbose does not seems to do the trick), so you have to help me on how show I get more details.

I'm using Windows 2012 R2. Maybe I need to install something on the system before installing this extension?

Hey Rui, can you zip up the contents of the following folder and send it to me?

$HOME\.vscode\extensions\ms-vscode.PowerShell-0.7.0\logs

You can just drop the zip file into the comment box and it should upload the file to GitHub.

Here it is:

Installing PowerShell 5.0 fixes the problem (Windows 2012 R2 comes with PS 4.0).

Ahhh! Yes, others have seen this issue too. Thanks a lot for sending along these logs. I'll track this issue over at #248 since a few people have reported it there as well. Glad you were able to get around it!
