@DevGeorge Thanks for the detailed bug report. This is a known issue that occurs when the auto-update process is interrupted partway through (typically due to network errors or system interruptions), leaving Claude Code in a partially updated state where critical files like yoga.wasm are missing.

The team is aware of this problem and working on making the update process more robust. In the meantime, I'd recommend trying our new native binary installation method, which tends to be more reliable and doesn't have this particular issue:
https://docs.anthropic.com/en/docs/claude-code/setup#native-binary-installation-beta

The native installer handles dependencies better and avoids the yoga.wasm issues entirely.

If you prefer to stick with npm for now, a clean reinstall should fix it:

npm uninstall -g @anthropic-ai/claude-code
npm install -g @anthropic-ai/claude-code

I was about to submit another bug report with uninstalling it.

npm uninstall -g @anthropic-ai/claude-code

Even using the force option doesnt work.

npm uninstall -g @anthropic-ai/claude-code --force

This was how I had to force-uninstall

rm /Users/devgeorge/.nvm/versions/node/v20.10.0/bin/claude
rm -rf /Users/devgeorge/.nvm/versions/node/v20.10.0/lib/node_modules/@anthropic-ai/claude-code\n

After which a new install works... For a little bit anyways

You may want to try claude /migrate-installer or using our native installation https://docs.anthropic.com/en/docs/claude-code/setup#native-binary-installation-beta

FWIW, I'm seeing this happening on what I'm pretty sure is a native install (not sure how to tell which one I have). Uninstalling with the npm command does nothing. How do I reinstall a native installation?

EDIT: I tried simply rerunning the installation script (currently curl -fsSL https://claude.ai/install.sh | bash), and after reloading my shell, that worked. But it does look like the native installation is also susceptible to this problem.

I too am using a native installation because I've had this issue once with the npm installation, and I've just encountered the problem again.

This worked for me.

Having this problem too.

rossvz · 11 months ago

Ran into this today - seems to be related to leaving the claude session open for a while. Ended up uninstalling and reinstalling and that seemed to resolve
