Hi! What was your solution to this error. Please share

[jmarandet]

Hi @shanalikhan , I am facing the same issue and would be thankfull to have any hint , did you found a way out of this issue ?

[shanalikhan]

I had updated some npm packages.
When i reverted them it worked.

[jmarandet]

Ok thanks a lot, I found my way out too !
Instead of reverting, I choosed to move forward with the following commands :
npm install -g node@latest
npm install -g npm@latest
npm install -g vscode@latest
npm install -g vsce@latest

I think this helped to correct some hidden issues (moving forward is always good isn't it ?), but I still had the same error log.
Then I copy/paste the corresponding 17th line in your log file, removing extra backslashes, and pasting it to a DOS CMD
"C:\Program Files\nodejs\node.exe" "C:\Users ... ...

Then it shows me some extra-logging information, the tsc -p ./ step raised some error in my plugin (an orphaned declared variabled that was not read anywhere, and an assignement that was facing a type-matching issue).
These errors didn't showed up when I was developping my plugin, but it seems that the tsc copiler is more strict.

So I fixed the remaining inconsistencies in my code, and run a succeeding vsce package.

Ourah !

Post Scriptum : I forgot to say that I also junked out the node_modules directory, and executed a npm install sometime, within my plugin directory.

Try npm run compile to get more error message.
