npm uninstall -g @anthropic-ai/claude-code and reinstalling didn't resolve my problem

Lillian-Yo · 4 months ago

I switch the npm from homebrew to nvm and then install claude code @2.1.118，resolve the problem

Vrq · 4 months ago

So what's the solution? Happening on npm and uninstall doesn't help.

alishaevn · 4 months ago

After executing brew install --cask claude-code, it updated claude and it now works again.

``` bash
==> Upgrading 1 outdated package:
claude-code 2.0.8 -> 2.1.118
==> Fetching downloads for: claude-code
✔︎ Cask claude-code (2.1.118)
==> Upgrading claude-code
2.0.8 -> 2.1.118

Run the official claude code installer. If that doesn't work, run claude --version and you may find it's still stuck on something really old such as:

2.0.22 (Claude Code)

So to find out what's running here, say: which claude and it will print the path to the old version that you need to remove. Then rm <path> on that path, and then next time you start claude, it should be the latest version.
