Cannot find module 'error/typed'

Recently I ran into following cryptic error:

❯ yarn start
yarn run v1.22.17
$ ember serve
Cannot find module 'error/typed'

No good results on Google and weird behaviour when even rolling back to previous (working) commit did not help made me experiment and conclude that there are only two things that could help.

How to fix

Using yarn-deduplicate

Often times the cruft accumulated in yarn.lock makes the whole project go boom. yarn-deduplicate can potentially help with this. Seen this in few instances, but(!) this did not fix the problem in my case.

❯ trash node_modules
❯ yarn global add yarn-deduplicate
❯ yarn-deduplicate
❯ yarn
❯ yarn start
yarn run v1.22.17
$ ember serve

Build successful (19933ms) – Serving on http://localhost:4200/
Enter fullscreen mode Exit fullscreen mode

Regenerate yarn.lock

This method worked for me.

❯ trash node_modules
❯ trash yarn.lock
❯ yarn
❯ yarn start
yarn run v1.22.17
$ ember serve

Build successful (19933ms) – Serving on http://localhost:4200/
Enter fullscreen mode Exit fullscreen mode

Notes

The trash command is an OSX utility for moving files or folder to the trash and you can replace it by calling rm -rf.
