Could not find/install babel plugin 'proposal-decorators':

Hi devs,

I’ve tried to deploy my react project on CodeSandBox, but it receives this error: Could not find/install babel plugin ‘proposal-decorators’.

I’ve tried a lot of ways, including adding this plugin dependencies, but still invalid.
My project runs fine on local host, but not shown up on CodeSandBox.

Please support if you know the answer. Thank you!

I would start over, push your code to Github and create a new CodeSandbox using the import from Github.

You are not using decorators and CRA doesn’t support decorators. If you did I’m guessing you’d have to eject to add the support.
