Answer 2

It appears the node version you're using isn't compatible. Can you try using node 10 or 12? I suggest using nvm to manage the different node versions.

Many packages define an explicit node version in their package.json . For example, in @babel/core :

"engines": {
  "node": ">=6.9.0"
},

It seems your node version: 13.0.0-nightly20190802452b393c1f isn't valud for these requirements.

You can see the source in yarn that handles this.

You can see here that it appears the semver package does not handle this:

import semver from "semver";

console.log(semver.satisfies("13.0.0", ">=6.9.0")); // true
console.log(semver.satisfies("13.0.0-nightly20190802452b393c1f", ">=6.9.0")); // false
