Problem with dependency tree with npm 7

[seblejeune]

Hi,

I use npm 7, docusaurus 2.0.0-beta and your docusaurus-plugin-sass.

I have a problem with the peer dependencies. Actually you set "@docusaurus/core": "^2.0.0" but npm 7 does not install pre-release dependencies with a '^'.

This possible for you to change and put >2.0.0-beta by example ?

As long as the release version of docusaurus hasn't officially been released.

This my stack trace when I install your plugin :

I got the same installation error when upgrading the version of Docusaurus. It would be great if we could fix the bug.

npm install --save docusaurus-plugin-sass sass

I have the same issue. With docusaurus version 2.0.0-beta.3 everything works fine but we'd like to upgrade to beta.6

I got the same issue here.
I did test with @docusaurus/core@"2.0.0" and @docusaurus/core@"2.0.0-beta.6", and the dependency problem is the same.

I made another test and if I try using yarn, the problem of dependency not happens, but I need to install sass module before run yarn/npm start, because it's not installing the peerDependency for sass-1.30.0.

If I add sass module after run yarn install, it runs and load right.

For now you can get this to install using npm install --save docusaurus-plugin-sass sass --legacy-peer-deps
