yarn build failed with a fresh created react ts app

[mielune]

Describe the bug

After creating a fresh new app using yarn create react-app my-app --template typescript the build process failed with an error from my_project/node_modules/react-scripts/config/webpack.config.js:664

Based on last releases of all componants inside node 16.13.0

Error is:

yarn build

I had the same error using npm.

Here is my package.json

{
  "name": "personal-website",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^5.16.1",
    "@testing-library/react": "^12.1.2",
    "@testing-library/user-event": "^13.5.0",
    "react": "^17.0.2",
    "react-dom": "^17.0.2",
    "react-scripts": "5.0.0",
    "web-vitals": "^2.1.3"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

And here is the error:

Problem is a change in the api coming from mini-css-extract-plugin which is versioned at ^2.4.5 in the react-scripts package. It resolves to 2.5.0 at react-scripts install time which isn't good. You can patch around this with this in your package.json temporarily.

{ "resolutions": { "mini-css-extract-plugin": "2.4.5" } }

I suspect mini-css-extract-plugin should have major-version-bumped if they're going to change their api that much.

... you do need to do a 'yarn install' or the like to re-resolve and make sure that the current jq .version < node_modules/mini-css-extract-plugin/package.json is 2.4.5 before the error will disappear.

Just try to edit /node_modules/react-scripts/config/webpack.config.js in line 19:
const MiniCssExtractPlugin = require('mini-css-extract-plugin').default;

It works for me :)

You're not wrong, but you're also hacking edits into node_modules which is not a sustainable path for deployable software.

Easy fix if you are a new developer, or just not very good with node_modules or if you're like me and just don't get the lango the others are speaking:

Delete "mini-css-extract-plugin" from your node_modules folder.
Run the command: npm install mini-css-extract-plugin@2.4.5
Try building again and it should work.

This seems to be the best fix right now. Thanks, guys!

Thank's it is working for me (I tried with 2.4.7 too).

Good workaround, waiting for a fix.

It may be good thing to temporary lock the release of mini-css between 2.4.5 and 2.5 in the react-scripts package.json.
