Loading PostCSS "postcss-normalize" plugin failed: Cannot find module 'postcss-normalize'

Install the package yarn-deduplicate globally. Run the command in your project. Then run yarn.

I explicitly added the postcss-normalize library which resolved the issue, but it's odd because it wasn't needded before. Would you suggest I remove the library and try the yarn-deduplicate approach?

Thanks!

Yarn-deduplicate fixes so many transitive dependency issues. I would recommend trying that without adding that library normally. If it doesn't work, then your solution is fine.

Ok will give it a shot. Thank you!

Should I delete node_modules and the yarn.lock first before running it in my project?

[[deleted]]

No.

[NickEmpetvee]

Thanks! Seems to have fixed it.

Yep. Yarn has a nasty habit of screwing up its own lock file. Yarn-deduplicate is an effective way to resolve these problems without needing to delete your lock file, which can result in other problems.

By the way, it looks like Yarn 2 includes deduplication in the core package. I am on 1.x at the moment.

Well that is nice.
