There is no cache on my CI and docs are built from scratch on every commit, but I'll try it in some hours.

[slorber]

I see Not in front of a computer atm but found your setup a bit weird. Why do you have docusaurus deps in 2 different packages Le sam. 1 mai 2021 à 10:49, MG. ***@***.***> a écrit :

The idea is to follow monorepo approach. There is one global package.json which has all the dependencies for all projects in the repo and they are installed on the root level.
docs are a project in the repo and the idea is that its package.json only describes desired dependencies and their versions (the same as in the global package.json), but all scripts use parent node_modules.

I'll try to play with scripts, maybe ../node_modules/.bin is the issue.

I am experiencing the same issue with

2.0.0-alpha.75 with i18n - https://pastebin.com/inhL60ap
2.0.0-alpha.74 with i18n - https://pastebin.com/GqYi0M8t

2.0.0-alpha.72 works but the i18n url breaks if there is a baseURL configured
as pointed out here: #3309

[slorber]

@wibed I don't understand how your problem is related to the current issue. This issue is a alpha 74 -> 75 upgrade problem.

Please open another issue with a repro repository that I can inspect. error building locale=en is a very generic message that will be printed whenever a site does not build. Will try to improve it to make this clearer

[wibed]

@slorber indeed it does not.

Ive mistakenly took the error, based on the message, for a similar problem.

Ive been able to fix my issue, by rebuilding on the new .75 version bit by bit.

[slorber]

This is not a problem in Docusaurus, but it is a problem in your repo @satanTime

After upgrading to alpha.75 (now on Webpack 5), you still end up with node_modules/webpack being Webpack 4, while Docusaurus needs Webpack 5.

It is your responsibility to not mess-up with the dependencies and ensure that Docusarus is able to use the Webpack version it needs, and I think your setup mess-up with the dependencies.

If you are not using npm/yarn workspaces and the hoisting features permitting multiple webpack versions to cohabit, you should then rather install docusaurus deps independently in the docs subfolder.

Eventually, you could try to add "webpack@5" at the root of your monorepo, it might permit Docusaurus to build, but it might break other things of your repo... this is not a solution I'd recommend.

This PR shows that your site can definitively build using latest Docusaurus: help-me-mom/ng-mocks#475

[satanTime]

Hi @slorber, thanks for the info... that is the thing I was afraid of. I tried webpack@5 in the global package.json but it didn't work out unfortunately.
I'll try to play with it more. Thanks for your help.

PS. Frankly speaking, I don't understand benefit of having a single package.json with all the deps... maybe one day... thanks again.
