Hi @btroncone and @toddmotto. Just started your RxJS course and the material gave me a bit of trouble.

Related: parcel-bundler/parcel#5943

I got through npm start by removing node_modules and package-lock.json and then using modified package.json as follows:

Modify:

  "dependencies": {
    "parcel-bundler": "1.12.3",
    "rxjs": "^6.5.3"
  },

Add:

  "resolutions": {
    "@babel/preset-env": "7.13.8"
  },

Now npm install and npm start and it works again.

The actual error:

$ npm start
