My company just switched on a new repo the Rust project I'm working on, to merge it with a Tauri project, and VS Code now gave me this error:

Failed to run build scripts

I can compile, run my project or use cargo check to see the warnings/error but Rust Analyzer is not working and it's very annoying for me to run cargo check every time i need to check my code.

This error occurs only on this repo, which contains a Rust workspace separate in two folders: one Tauri/Rust project and one basic Rust project.

Cargo.toml at the root:

[workspace]

members = [
    "builder",
    "studio/src-tauri"
]

Error details:

[ERROR rust_analyzer::lsp_utils] failed to run build scripts:
The following warnings were emitted during compilation:


error: failed to run custom build command for `cairo-sys-rs v0.15.1`

Caused by:
  process didn't exit successfully: `/home/korocouille/Sogilis/IReflex/reflex2/target/debug/build/cairo-sys-rs-decf14405d906ced/build-script-build` (exit status: 1)

  Package cairo was not found in the pkg-config search path.
  Perhaps you should add the directory containing `cairo.pc'
  to the PKG_CONFIG_PATH environment variable
  No package 'cairo' found

I tried to uninstall and re-install Rust-Analyzer, switch to pre-release or older version, delete my target folder, run a cargo clean cmd but nothing changed, and I can't find any solution.

I had the same problem. It was because the environment paths from export-esp.ps1 script, only added temporarily.

So I added them manually in windows. and now it seems to work.

  • Ok thank i'll try this but ... how do i can manually change it ? Sorry if it's an obvious question, im not that much familiar with that – Noe Baiocchi Mar 14 '23 at 08:59

If you are on windows search for "environment variables" and click on the button on the almost bottom right named "environment variables". Then click on path in user variable and click edit. Then just add the paths without the code and "'s

Hope it helps

Edit: I would have added as a comment, but I dont have enought rep to do so.
