Try the pre-release build.

down to the warnings below:

It also now starts to display code errors and warnings but only for opened files

[lnicola]

Failed to discover cargo config env: "C:\Users\Admin.cargo\bin\cargo.exe" "-Z" "unstable-options" "config" "get" "env" failed, exit code: 101

That was fixed in #17744

error: the --keep-going flag is unstable, pass -Z unstable-options to enable it

You need to upgrade your toolchain, see #17608.

[Shinribo]

Thanks now it works.

[Shinribo]

Also it didnt work at first bc apparently llvm changed the data layout for x86-64 when using a custom target tripplet.

[lnicola]

Yeah, if you're stuck on an old nightly, you might need to use an old r-a, we can't realistically support every Rust version out there.

[Shinribo]

luckily i just forgot about setting a newer toolchain in my project

[zxq5-dev]

I'm stuck using an older version of rust (1.68.0 nightly)
how would i go about installing an older version of rust analyzer?

[ChayimFriedman2]

@FantasyPvP In VSCode you can right-click on rust-analyzer on the Extensions view and choose "Install Specific Version...". For other editors this depends on how you installed rust-analyzer, for example if via rustup you just need to install the rust-analyzer component on the toolchain.
