Sass在create-react-app中不起作用

Question

Sass does not compiling in create-react-app. The current package.json structure is

{
  "name": "create-app",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.3.1",
    "react-dom": "^16.3.1",

Answer 1

It is working fine, npm start watch your .scss files and output .css files as expected.

Make sure to require the .css files in your components.

Since src/App.js still imports src/App.css , the styles become a part of your application. You can now edit src/App.scss , and src/App.css will be regenerated.

Also since .css files are now generated, you should remove them from your SCM.

At this point you might want to remove all CSS files from the source control, and add src/**/*.css to your .gitignore file.

The 2. version of create-react-app supports Sass now. Install node-sass (eg npm install node-sass) to enable it. Checkout this application's Navigation component .
