Angular Production Build Could Not Find Plugin "proposal-numeric-separator"

Viewed 880

When taking production build I am getting error like Could not find plugin "proposal-numeric-separator". Ensure there is an entry in ./available-plugins.js for it. Here I have attached my error screenshot. We have added "@babel/preset-env": "^7.8.7", in dependencies as well.

Had the same issue during angular 8 PROD build. Following has fixed in dev dependencies:

"@angular-devkit/build-angular": "^0.803.23"    
"@babel/compat-data": "^7.8.0"

Hope it helps.
