[BUG] CC crashes with new release of Nodejs v25

Open arimxyer opened this issue 2 months ago • 7 comments

Preflight Checklist

  • [x] I have searched existing issues and this hasn't been reported yet
  • [x] This is a single bug report (please file separate reports for different bugs)
  • [x] I am using the latest version of Claude Code

What's Wrong?

Error reads: TypeError: Cannot read properties of undefined (reading 'prototype').

CC's dependency chain includes packages that rely on the deprecated SlowBuffer API, which has been removed (marked as "End-of-Life") in Node.js v25.0.0 per DEP0030.

Node.js Reference: • Official Deprecation Doc: DEP0030 • Node.js v25.0.0 just released (October 15, 2025)

What Should Happen?

It should launch :)

Additional Information

NodeJS offers a fix - not sure if it's a drop-in replacement, I'd imagine not. (https://nodejs.org/api/deprecations.html#DEP0030).

This might also be a fix?

  • Update transitive dependencies (particularly buffer-equal-constant-time in the JWT authentication chain) to use crypto.timingSafeEqual() instead of SlowBuffer.prototype.equal.

Sorry about this, but it looks like we are stuck waiting on some dependency updates here We are switching to recommending our native builds soon: https://docs.claude.com/en/docs/claude-code/setup#native-binary-installation-beta

  1. ✅ jwa - Already fixed in v1.4.2 and v2.0.1
  2. ❌ jws - Needs to release v3.2.3 with jwa@^1.4.2 (or users need to use v4.0.0)
  3. ❌ jsonwebtoken - Needs to update to [email protected] or [email protected]
  4. ❌ @azure/msal-node - Will automatically get the fix once jsonwebtoken updates
