FAQ

  • Q: I get an error running vyper on my macbook with M1/M2 chipset.
  • A: The extension executes the vyper compiler in a /bin/sh shell that may not have all the customizations you are using in your day-to-day shell/terminal. As a workaround, I suggest to set the setting:vyper.command to arch -x86_64 vyper. see #18

Developer Notes

  • install vyper pip3 install vyper
  • use the script in ./scripts/fetch_vyper_language_spec.py or run npm run fetchGrammar to merge the python tmlanguage spec with vyper language specifics.
