While rebasing on the latest changes on `next`, especially #14160, I noticed that my local `pnpm build` step was no longer working and erring with the following: ``` │ > @tailwindcss/oxide@4.0.0-alpha.19 build /Users/philipp/dev/tailwindcss/crates/node │ > npx napi build --platform --release --no-const-enum │ │ Type Error: Could not parse the Cargo.toml: Error: Command failed: cargo metadata --format-version 1 --manifest-path "/Users/philipp/dev/ │ tailwindcss/crates/node/Cargo.toml" │ error: rustup could not choose a version of cargo to run, because one wasn't specified explicitly, and no default is configured. │ help: run 'rustup default stable' to download the latest stable release of Rust and set it as your default toolchain. │ │ error: rustup could not choose a version of cargo to run, because one wasn't specified explicitly, and no default is configured. │ help: run 'rustup default stable' to download the latest stable release of Rust and set it as your default toolchain. ``` It turns out that with the changes in turbo v2, env variables no longer propagate to the individual tasks automatically but since I installed rustup outside of the default `~/.rustup` directory, the task was no longer able to find it. To fix this, we now define `RUSTUP_HOME` as a global env to always pass through.
