This error indicates that the version of npm you're running is too old. Upgrade
by running:

```sh
npm install -g npm@latest
```

See the [following `node-gyp` issue](https://github.com/nodejs/node-gyp/issues/972) for more details.



### ```ModuleNotFoundError: No module named 'distutils'`

Your version of python is too recent for node-gyp to work;
Use a version <= 3.11 and it should work.
