On ARM, Homebrew installs into /opt/homebrew instead. Is it<br>possible that your Homebrew installation was migrated from a previous<br>x86_64 machine? You might consider removing and reinstalling Homebrew<br>so you have native ARM binaries. That should also fix the error<br>you're seeing.<br><br>--Benjamin Gilbert<br></div></div></blockquote></div><br></div></body></html>
