Troubleshooting​

Import errors after library installation​

Issue: After running chr install to install libraries (such as FT4), import statements in your main.rell file may still show errors in the VS Code editor, even though the installation was successful.

Example: If you use import lib.ft4.accounts.strategies.transfer.fee; in main.rell but haven't installed the FT4 library yet, you'll see an import error. After setting up chromia.yml for FT4 and running chr install, the error may persist in the editor.

Solution: Close and reopen the affected files in VS Code to refresh the editor's understanding of the newly installed libraries.

Workaround: You can also use the Command Palette (View -> Command Palette) and run the Rell: Invalidate index caches command to force the extension to recognize newly installed libraries.

tip

This is a known limitation where the VS Code Rell extension doesn't automatically detect newly installed libraries until files are refreshed or caches are invalidated.
