Babel Error on start - clean app

[skoliver89]

Describe the bug

I created a new/clean react app and on first run of the start script with no edits I get a Babel Error.
See below for my CLI outout.

$ npx create-react-app price-grid

Initialized a git repository.

Success! Created price-grid at C:\Users\soliver\Documents\react_module_dev\price-grid
Inside that directory, you can run several commands:

  npm start
    Starts the development server.

  npm run build
    Bundles the app into static files for production.

  npm test
    Starts the test runner.

  npm run eject
    Removes this tool and copies build dependencies, configuration files
    and scripts into the app directory. If you do this, you can’t go back!

We suggest that you begin by typing:

  cd price-grid
  npm start

Happy hacking!

Reproducible demo

I didn't change anything from what is provide immediately after running create-react-app

[NielXu]

I have the same issue

[im-stuart]

I experience the same issue. Worked fine a week ago.

[CRHarding]

Same issue for all 25 of my students.

[Oswirrex]

Same

[oohwooh]

This is happening to me as well

[bourdakos1]

Same for me, was working fine 2 hours ago

[lfernando-silva]

react-scripts stoped to work for me by this error (as I cleaned the node_modules)

[nicolairhs]

Same here.

[oohwooh]

Looks like it's because the npm cache hasn't been updated yet, it's a bug in core-js-compat zloirock/core-js#713

should fix itself soon?

[nicolo-ribaudo]

The fix has been released 1 hour ago but it isn't downloaded by npm: npm/cli#545
Please 👍 that issue.

[skoliver89]

Well... isn't that niffty. Thanks for the heads up!

[jawee]

If you need it to work now and you cant wait for npm to be updated, you can run this:
npm install core-js-compat@3.4.7
It made it work for me at least.

[oohwooh]

if you run npm i -D core-js-compat@3.4.7 it should resolve the problem. Worked for me. parcel-bundler/parcel#3864 (comment)

[skoliver89]

Sounds like we this issue is out to the hands of this team.
We also have interim fixes provided by @jawee and @DragonBallZeke
Therefore, I am going to close my issue.

Thanks for all of the support my dudes! 😄

[skoliver89]

just as an update:

Looks like npm got their stuff fixed. It should work now as intended. (I just verified it on my machine)

npm steps:

1. delete node_modules & package-lock
2. remove core-js-compat from package.json dependencies if you installed it
3. run npm install

As the create react app team likes to say... "Happy Hacking!" 😄
