Problem

When using VSCodium, the server fails to start with the following error message:

2026-07-27 00:37:29.430 [info] Starting language client
2026-07-27 00:37:29.442 [error] Bootstrap error Error: rust-analyzer Language Server is not available. Please, ensure its [proper installation](https://rust-analyzer.github.io/book/installation.html).

After uninstalling and reinstalling the rust-analyzer extension the issue persisted.

Steps

1. Install the rust-analyzer extension on the target environment
2. Start the server.

Possible Solution(s)

No response

Reproduce the listed installation and startup steps in VSCodium on Arch Linux, then inspect the bootstrap failure reported from the extension's out/main.js and compare the installation state with the rust-analyzer installation guidance. Done means the rust-analyzer language server starts successfully in the target environment.
