Node.js v14 Warning: Accessing non-existent property ___ of module exports inside circular dependency

[fishcharlie]

🐛 Bug Report

On Node.js v14 there are a lot of warnings when using docusaurus v2. These warnings do not occur when running Node.js v13.13.0.

Have you read the Contributing Guidelines on issues?

Yes

To Reproduce

1. Install Node.js v14.0.0
2. Run npm start on a docusaurus v2 project (looks like it occurs on npm run build as well, maybe others)

Expected behavior

No warnings or errors to occur in Node.js v14.0.0 (ie. same behavior as Node.js v13.13.0)

Actual Behavior

Lots of warnings displayed (see logs below).

It looks like this is related to nodejs/node#32987.

[lex111]

It seems that this is due to one of the dependencies we use. We will wait for patch version shelljs/shelljs#991

Coincidentally, the same question to me. When i change the NodeJs's version to 13.13.0, the problem disappear.
