Running into this exact issue as well, trying to install [Jest](https://jestjs.io/docs/getting-started). ``` 42 verbose stack TypeError: Cannot set properties of null (setting 'peer') 42 verbose stack at visit (C:\Users\\AppData\Roaming\nvm\v16.15.1\node_modules\npm\node_modules\@npmcli\arborist\lib\calc-dep-flags.js:104:54) 42...
