Here is the full error output:

Test suite failed to run

    TypeError: Cannot read properties of undefined (reading 'read')

      2 | const { default: axios } = require('axios');
      3 | const fs = require('fs');
    > 4 | const mockFs = require('mock-fs');

The module mock-fs is definitely installed, and I have deleted node_modules and reinstalled...

I am using VSCode on WSL1.

How do I import mock-fs?
