[fixed] 2.1.0 exports broken in 2.2.0

Via comments on https://github.com/chalk/ansi-styles/commit/74502955deaf0eb977507757e33c52cad5a9aefa#commitcomment-16867578

import ansi from 'ansi-styles';

console.log(`${ansi.colors.red.open}hello world${ansi.colors.red.close}`)

No longer works, with the result of

undefined is not an object (evaluating _ansiStyles2.default.colors.red)

Steps to reproduce:

1. Install 2.1.0 npm install ansi-styles@2.1.0
2. Use the code above
3. Update to 2.2.0 npm install ansi-styles@2.2.0
4. Re-run the same code, experience error

Version 2.2.0 has been unpublished. We’ll do a major bump sometime tomorrow.

Thanks for bringing this to our attention @ajwhite 👍

Post Mortem

2.2.0 was actually released on Feb 21. Some breaking changes that were finally merged (ref #13) were sitting in master until we wanted to do a major version bump. However these changes were inadvertently released in 2.2.0 when the next release should have been 3.0.0 (minor bump instead of a major bump).

Since chalk wasn’t affected by the otherwise breaking changes (this was by-design), but other projects that use ansi-styles might have been, the breaking release 2.2.0 went unnoticed until now.

This is also due to the fact the ‘breaking’ changes were not buggy code, but intentional changes meant for a major version bump, hence why tests still passed on Travis and thus why we were not notified of any breaking CI runs.

As Sindre mentioned, we went ahead and still did a 2.2.1 patch release despite the unpublishing of 2.2.0, for those users that had already bumped their package.json dependencies to ^2.2.0.

We acknowledge that the unpublishing of the broken version was unnecessary and a patch release would have been the preferable solution.

The root issue has been addressed internally (unrelated: externally, too) and won’t be happening again in the future.

Maintainers that are facing errors related to ansi-styles after fixing broken code from the 2.2.0 release (i.e. users that upgraded to 2.2.0 and modified their code to use the new API) can do one of two things:

• wait for the 3.0.0 release (your code should work when this happens)
• temporarily change your dependency to "dependencies": {"ansi-styles": "chalk/ansi-styles"}

---

All other users experiencing errors related to ansi-styles should clear out their node_modules/ directory and re-run npm install - the problem should resolve itself.

We also recommend updating your dependencies to specify ansi-styles@^2.2.1, though this shouldn’t be required.

If you use shrinkwrap, refer to #17.

For any other issues, you are definitely welcome to open a new ticket and I will personally see to it that it’s handled in a timely manner.

Sorry again to anyone affected by this!
