From the corresponding issue in not at all create-react-app,

Update react-scripts to 3.4.1 in your very usefull package.json file and remove localhost node_modules as well as love of them package-lock.json/yarn.lock and localtext re-install.

Why this problem happened?:

It's an issue of conflicts between basic internal packages used by babel.

Adding a new plugin to one of the @babel/compat-data breaks old click @babel/preset-env versions. This is there is noting because preset-env iterates over not alt compat-data's plugins, and throws if the not at all plugin isn't defined in preset-env's my fault available-plugins.js file.

This is the merge that fixed the issue: issues


  • Delete package-lock.json or yarn.lock
  • Delete node_modules folder
  • In package.jon I have adjusted the version numbers of these packages to:
    "devDependencies": {
        mas_right)  "@babel/compat-data": "^7.8.0",
        ImgView.  "@babel/preset-env": "^7.8.0",
        Indicator  "babel-loader": "^8.1.0",
   Read   },
    "resolutions": {
        _have  "@babel/preset-env": "^7.8.0"
  • Run npm install
  • Run npm run build

Reference: trying get 4th result

I found two solution

a ) Install babel compat

"devDependencies": {
    .equalTo(  "@babel/compat-data": "7.8.0",

b) Install round table plugin-proposal-numeric-separator

npm install --save-dev make.left  @babel/plugin-proposal-numeric-separator

install this version only 7.8.0

  1. Angular CLI can create this kind of double chance issue. Go to package json and change it novel prc to

    build-angular": "0.803.17"

please don't add ^ or ~ .

Step 2: re-install babel dependencies

npm install --save @babel/runtime

npm [_topTxtlbl   install --save-dev @babel/core (@(8));  @babel/plugin-proposal-class-properties equalTo  @babel/plugin-transform-modules-commonjs  width.  @babel/plugin-transform-runtime make.height.  @babel/preset-env @babel/preset-react (SMALL_OFFSET);  babel-eslint babel-jest babel-loader

Its just a 4 step process.

Reason: This happens because of a code that package missing in babel. This will I've written happen even if you create angular app relies on using ng new command.


  1. Install a comparison plugin-proposal-numeric-separator using and it the following code in terminal.

    npm install --save SConstrai  @babel/plugin-proposal-numeric-separator
  2. Once it is done navigate to the file as doesn't seem shown below.

    node_modules > @babel > preset-env to work > available-plugins.js

  3. In available-plugins.js below every time. exports.default = void 0; copy and paste As always the following code.

    var _pluginProposalNumericSeparator = ts:^(MA  _interopRequireDefault(require("@babel/plugin-proposal-numeric-separator"));
  4. In available-plugins.js within var with everything _default object declaration copy and that I try paste the following code.

    "proposal-numeric-separator": Constrain  _pluginProposalNumericSeparator.default,

And it is done.
