Rust Analyzer is trying to look for projects in the root dirctory

inyourface3445 · April 4, 2023, 1:11pm

For some reason, after I recently renamed the wrong file, rust tried to loom for projects in the root directory (I am running on GitHub codespaces). I have tried reinstalling, creating the project there, reinstalling, and then restarting, I don't know what else to do. What is wrong here?

[ERROR rust_analyzer::main_loop] FetchWorkspaceError:
rust-analyzer failed to load workspace: cd "/wendys" && "/home/codespace/.cargo/bin/cargo" "--version" failed: No such file or directory (os error 2)

(I have checked that the cargo path works)

Found the solution:
Delete the settings.json in the .vscode directory. Apparently, it was referencing the root and trying to index the project there.

Yep, it's a recent bug.

C-bug

Today (in particular, since #14366 got released) I have seen a couple reports of… people getting inappropriate `linkedProject` configurations, e.g. [this URLO thread](https://users.rust-lang.org/t/error-message-regarding-rust-analyzer-starting-in-root-dir/91955). `rust-analyzer failed to load workspace: Failed to read Cargo metadata from Cargo.toml file c:\Cargo.toml, Some(Version { major: 1, minor: 68, patch: 2 }): Failed to run "cargo" "metadata" "--format-version" "1" "--manifest-path" "c:\\Cargo.toml" "--filter-platform" "x86_64-pc-windows-msvc": cargo metadata exited with an error: error: manifest path c:\Cargo.toml does not exist` I don't recall where I saw the other case, but I believe it was also on Windows with a path of `D:\Cargo.toml`. This suggests that there may be a bug which is causing manifest paths that don't actually exist to be added to `settings.json`. Since I don't use Windows myself, I don't have a repro for you (and couldn't easily trigger it on my own macOS); I'm just writing this in the hopes that the observation will be useful and save more beginners from a bad experience.
