没有效果啊 打出来的包还是很大

[xiao-ben]

 "scripts": {
    "analyze": "source-map-explorer 'build/static/js/*.js'",
    "start": "react-app-rewired start",
    "build": "react-app-rewired build",
    "test": "react-app-rewired test",
    "eject": "react-app-rewired eject"
  },

用这个 打包是

318.02 KB  build/static/js/2.4b1709c5.chunk.js
  24.66 KB   build/static/css/2.a3a7d6af.chunk.css
  886 B      build/static/js/main.070194f8.chunk.js
  761 B      build/static/js/runtime~main.fdfcfda2.js
  540 B      build/static/css/main.bc5faf9d.chunk.css

然后我用正常的方式进行打包 结果如下

 "scripts": {
    "analyze": "source-map-explorer 'build/static/js/*.js'",
    "start": "react-app-rewired start",
    "build": "react-scripts build",
    "test": "react-app-rewired test",
    "eject": "react-app-rewired eject"
  },

这样打包之后是
