Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Prerequisites

• I'm using the latest version of Docusaurus.
• I have tried the npm run clear or yarn clear command.
• I have tried rm -rf node_modules yarn.lock package-lock.json and re-installing packages.
• I have tried creating a repro with https://new.docusaurus.io.
• I have read the console error message carefully (if applicable).

Self-service

What...? We migrated away from wait-file two years ago! Could you try installing it locally?

[Josh-Cena]

Never mind, this file is corrupted somehow:

https://unpkg.com/browse/@docusaurus/[email protected]/lib/webpack/plugins/WaitPlugin.js

[johnnyreilly]

https://github.com/johnnyreilly/blog.johnnyreilly.com/actions/runs/2772875207

Adding it directly to the project fixes the build by the looks of it: yarn add wait-file -D

[Josh-Cena]

You shouldn't need to... that file is suddenly reverted to the 2-year-ago version

[johnnyreilly]

Super weird

[slorber]

fixed in 2.0.1

[johnnyreilly]

I think you can still republish - if I recall there's like a 48 window where you can do that with npm modules

[Josh-Cena]

Yes, that's what I remember too.

Also getting this error after upgrading to 2.0.0, just ran npm install on 2.0.0 10 minutes ago (so I guess the 2.0.0 packages haven't been patched retroactively yet?).
Is 2.0.1 available somewhere or how can I get the fixed version?

As a side note, GitHub still lists 2.0.0-rc1 as the latest release and the changelog for 2.0.0 is also missing: https://docusaurus.io/changelog
Let me know if I should open separate issues for these

[Josh-Cena]

2.0.1 was released more than 24 hours ago. See https://www.npmjs.com/package/@docusaurus/core?activeTab=versions

@slorber Could you update the GitHub release?

[rguldener]

Thanks for the swift reply @Josh-Cena, didn't check NPM and didn't realize 2.0.1 is out because the docs & everything else only mention 2.0.0. Should have checked NPM I guess :)

I actually followed the update guide and since that also mentioned putting 2.0.0 into package.json that is just what I did: https://docusaurus.io/docs/installation#updating-your-docusaurus-version
Just as a heads up, might be worth changing 2.0.0 to 2.0.1 (or whatever the latest patch is) at least there :)

[Josh-Cena]

Yes, we should rename the current version on the website to 2.0.1. @slorber WDYT?

[slorber]

will update the version name in #7922
