I am trying installing it manually, but cannot solve. Someone can help me, please? Thank you!

After launching npm install --legacy-peer-deps now is working, but what was the problem?

NPM is not handling the deps in the best way. We are still looking for a workaround. In our V3 branch this problem is probably gone.
