This is caused by new npm@7 (shipped with nod@15) is installing peer dependencies by default and a dependency we use (mobx-react) specifies the wrong peer dependency:

mobx@"^5.15.4 || ^4.15.4" from [email protected]

As a workaround use the LTS version of node.js.

I will open a pr aginst mobx-react later.
