Autoprefixer doesn't work out of the box #9903

Open xitanggg opened 4 years ago

Describe the bug

In the Create React App doc, it says

This project setup minifies your CSS and adds vendor prefixes to it automatically through Autoprefixer so you don’t need to worry about it.

This doesn't seem to be true however.

Steps to reproduce

npx create-react-app my-app
cd my-app
npm run build

When I inspect build/static/css/main.xxx.chunk.css, I expect to see

.App-header {
  display: -webkit-box;
  display: -ms-flexbox;
  display: flex;

but I get

.App-header {
  display: flex;

meet the same problem when using the latest CRA （react-scripts@4.0.1）

yarn build and the result CSS like below:

.wrapper{
    display: flex;
    justify-content: center;
    align-items: center;
}

and the value was not been computed:

.amd-form-item-default-label {
    flex-basis: 173 * 0.5 * 1px;
    margin-right: 24 * 0.5 * 1px;
}

Last, I made sure again that my configuration is correct in package.json: 

"browserslist": {
    "production": [
      "Android >= 5.0",
      "Chrome >= 60",
      "iOS >= 9"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
