Steps tried: I thought the issue is missing proposal-numeric-separator module, so installed the module via below command
npm i @babel/plugin-proposal-numeric-separator
Still the issue did not resolved, so tried the answer given in the similar issue, still same error occurred.
How to fix this issue?
Thanks to nicolo-ribaudo from issue8680
Adding the dependency @babel/compat-data": "7.8.0" fixed the issue for me.
vi package.json
"dependencies": {
"@babel/compat-data": "7.8.0",
...
}
npm install
ng build --prod
It work's for me
Step 1: add in in your devDependencies: "@babel/compat-data": "7.8.0"
Step 2: run - npm install
