javascript - Jest TypeError: Path must be a string. Received undefined

Question

Below settings for my package.json

If I run from command line npm test all jest test cases are executed properly. In case I use directly the command jest from command line I receive this error:

Test suite failed to run

TypeError: Path must be a string. Received undefined

  at assertPath (path.js:7:11)
  at Object.relative (path.js:538:5)

This happens on any test files.

Any idea what could be wrong and how to fix it?

 "scripts": {
        "test": "standard && jest",
        "format": "standard --fix",
        "start": "webpack-dev-server --config webpack.config.dev.js",
        "build": "webpack --config webpack.config.prod.js"
    },

I solved this issue using:

• npm uninstall -g jest
• npm install -g jest
• npm cache clean
• npm install
