Cannot read property 'env' of undefined

I am unable to start my app unless I failed to follow instructions. The error is: context.env === "production" ? sassRule.loader : sassRule.use;

package.json:

  "dependencies": {
    "@craco/craco": "^2.4.0",
    "antd": "^3.11.0",
    "craco-antd": "^1.5.0",
    "react": "^16.6.3",
    "react-dom": "^16.6.3",
    "react-scripts": "^2.1.1"
  },
  "scripts": {
    "start": "craco start",
    "build": "craco build",
    "test": "craco test"
  },

craco.config.js

const CracoAntDesignPlugin = require("craco-antd");

module.exports = {
  plugins: [{ plugin: CracoAntDesignPlugin }]
};

Any ideas?

When running running craco start with NODE_ENV set to production, the process prints out this exception. The problem was actually me trying to run craco in production mode. You should not run craco in production, you should run craco build. My suggestion is that craco exits with a polite error message telling you not to run craco in production mode.

$ NODE_ENV=production npm start

> sosialhjelp-innsyn@0.1.0 start /Users/thomasfl/workspace/sosialhjelp-innsyn

Awesome, and thanks for the tip! I didn’t realize Travis CI supported Windows now, so that’s awesome! I’ll try to get the tests running on Windows as well.
