VSCode language server won't start

Hi all

The VSCode language server won’t start for me. I’m using Windows 10, julia-1.7.0-beta3, VSCode-1.58 and VSCode extention juliainsider-1.3.13. I get the following error

We don’t support 1.7 yet.

Oh ty!

Hi,

not trying to necropost, but I don’t think this problem is limited to 1.7.
I just freshly installed julia 1.6.2 (didn’t even notive the new patch release unitl language server didn’t start) with the current stable releases of VSCode (1.85.2) and the Julia Extension (1.2.7). Julia outputs:

julia> versioninfo()
Julia Version 1.6.2

Environment:

And the language server extension also crashes:

From my end this look like this was introduced by this PR where a stricter type enforcement for the Manifest was introduced in Pkg.jl. Before it used const Manifest = Dict{UUID,PackageEntry} but now has a new type simply called Manifest. This was then backported into 1.6.2 here I guess.

I think going back to julia 1.6.1 would solve this issue for now.

This should be fixed now in the latest vscode julia extension build, for 1.6.2 and up

Great! Thanks!
