-## Troubleshooting
-
-You may run into this error when using `rye` and `pyo3` together:
-
-```plaintext
-<compiler output>
-= note: ld: warning: search path '/install/lib' not found
-          ld: library 'python3.12' not found
-          clang: error: linker command failed with exit code 1
-```
-
-This seems to be a [bug in `rye`](https://github.com/astral-sh/rye/issues/1050#issuecomment-2079270180).\
-To work around the issue, run the following command in the root of the course repository:
-
-```bash
-cargo run -p "patcher"
-```
-
-`wr` should now be able to build the extension module without issues and run the tests. No linker errors
-should be surfaced.
-
-<div class="warning">
-
-The `patcher` tool is a temporary workaround for a bug in `rye`.\
-It hasn't been tested on Windows: please [open an issue](https://github.com/mainmatter/rust-python-interoperability/issues)
-if you encounter any problems.
