Additional Information

  1. claude doctor assumes Claude Code was installed via the standalone Windows installer and hardcodes C:\Program Files\ClaudeCode\ as the expected path
  2. When installed via npm/nvm, that directory doesn't exist
  3. Instead of detecting this and printing something like "not installed via standalone installer, skipping auto-updater check", it segfaults

That's a clear bug — a missing directory should never cause a crash. It should be handled gracefully.

You can report it at https://github.com/anthropics/claude-code/issues with these details:

  • Claude Code version: 2.1.119
  • Install method: npm via nvm (/c/nvm4w/nodejs/node_modules/@anthropic-ai/claude-code/)
  • OS: Windows 11 Pro (arm64)
  • Repro: claude doctor → exit code 139 (segfault)
  • Root cause: C:\Program Files\ClaudeCode\ does not exist (npm install, not standalone installer)

※ recap: We diagnosed errors in Claude Code's debug logs. The one open action is filing a bug report at github.com/anthropics/claude-code/issues for the claude doctor segfault when Claude Code is installed via nvm. (disable recaps in /config)

extent analysis

TL;DR

The most likely fix is to modify the claude doctor command to handle the case where Claude Code is installed via npm/nvm and the expected directory C:\Program Files\ClaudeCode\ does not exist.

Guidance

  • Verify that the issue is indeed caused by the missing directory by checking the installation method and the presence of the C:\Program Files\ClaudeCode\ directory.
  • Consider modifying the claude doctor command to detect the installation method and print a warning message instead of crashing when the directory is not found.
  • Check the Claude Code documentation to see if there are any known workarounds or fixes for this issue.
  • File a bug report at https://github.com/anthropics/claude-code/issues with the provided details to request a fix.

Example

No code snippet is provided as the issue does not contain sufficient information to create a concrete example.

Notes

The issue seems to be specific to the Windows platform and the installation method via npm/nvm. The fix may not be applicable to other platforms or installation methods.

Recommendation

Apply workaround: Modify the claude doctor command to handle the case where Claude Code is installed via npm/nvm and the expected directory C:\Program Files\ClaudeCode\ does not exist, as this is a known bug that causes a segfault.
