claude-code - 💡(How to fix) Fix [Bug] VS Code extension crashes with "illegal hardware instruction" on Intel Mac (no AVX2) [1 comments, 2 participants]

Error Messages/Logs

TL;DR

The issue is likely due to the Claude Code VS Code extension requiring AVX2 instructions, which are not supported on the user's Intel Mac Pro 2013, and a workaround or update to a compatible version may be necessary.

Guidance

• The error message "illegal hardware instruction — AVX2 missing" suggests that the Claude Code extension is attempting to use AVX2 instructions, which are not available on the user's hardware.
• To verify the issue, try running the claude auth login command on a different machine with AVX2 support to see if the error persists.
• Consider checking the system requirements for the Claude Code extension to see if it explicitly requires AVX2 support.
• Look into potential workarounds, such as using a different version of the Claude Code extension that may not require AVX2 instructions.

Example

No code snippet is provided as the issue is related to hardware compatibility rather than code.

Notes

The user is using an older Mac Pro 2013, which may not support the latest instructions required by the Claude Code extension. The issue may be resolved by using a different version of the extension or updating to a newer machine with AVX2 support.

Recommendation

Apply workaround: The user should try to find a version of the Claude Code extension that does not require AVX2 instructions, or consider using a different machine with AVX2 support to run the extension.
