vscode.d.ts could not be installed - visual-studio-code

Question

when I tried to run vscode-install, it would fail to sync vscode.d.ts. The problem seems random, most of our machines could not success, but two of our machines could success.
The error information is as follows:
Detected VS Code engine version: ^1.23.0

Answer 1

I had a similar problem, where the VSCode engine in package.json was very old (1.32.0) compared to the current VSCode version (1.64.2). I just updated the engine to the same as my VSCode version in package.json:
"engines": {
"vscode": "^1.64.2"
},
and the tests runner proceeds instead of erroring as before.
Unfortunately, I then got another error:
Error: Running extension tests from the command line is currently only supported if no other instance of Code is running.
which is a different problem and a limitation of VSCode at the moment (1.64.2), though there is a workaround for that.
