Language Service Startup Failure

[mrfusion9k]

Issue Type: Bug

I get the following error as soon as I install the Powershell Module. I've tried the other remediations with this issue before but they didn't help resolve the issue:

Are you seeing any errors in the console?

[mrfusion9k]

I see them as popup notifications when I start powershell or install the powershell module. I then get the prompt to copy the console from there and file a bug or try to fix it.

But in the console, which is to say the terminal, what do you see?

Can you try the extension build from #2719 (comment)

[mrfusion9k]

Nothing appears in the terminal. I only see something in the notifications box and get the button to show logs to send to support. I also tried the extension you recommended and it immediately errored.

[rjmholt]

and it immediately errored.

Did it error in the same way? We need as much information you can provide to try and fix the problem. That means:

• Where the error appeared
• The error text/message
• Ideally a screenshot/gif

If it helps: The Powershell version caused this issue for me.

Was just having the same issue when I came across this thread; I was running 6.2.3 but my coworkers had no issues and I learned they were on 7.0.3. Installed the latest Powershell and now the plug-in works fine. That pwsh.exe path looks like it may be 6.x.x (Powershell Core) and not the latest 7.x.x which is installed to: C:\Program Files\PowerShell\7\

This is the issue solved by the build in #2719 (comment)

When I tried to install that extension it threw this:

You're running it with Visual Studio's VSIX installer. You need to install it with VSCode's.

In the command line: code --install-extension ./path/to/PowerShell-Insiders.vsix

I thought that might be a similar problem and updated my version as well but it didn't help.

[mrfusion9k]

That fixed it. I can run powershell commands and scripts now without errors. Thanks for your help.
