Could not find plugin "proposal-numeric-separator"
The following steps work:
- Add the following line to
package.json
:
"resolutions": { "@babel/preset-env": "7.5.5" },
- Run the following command:
$ npx npm-force-resolutions
- Install dependencies:
$ npm install# or $ yarn
- Build your project:
$ yarn build
Take a look at this Github Issue
Try this, it works: npm i @babel/compat-data@7.8.0
I have just used it like 10 minutes ago, and it's working fine.
