vue-cli项目升级webpack4之后如何配置?

Question

项目原来是vue-cli生成的,今天更新webpack-dev-server之后要求要webpack升级到4,升级之后进行了一系列的配置,在升级babel的时候,不知道该如何配置解决了,现在跑不起来了.

"devDependencies": {
    "@babel/core": "^7.3.4",
    "@babel/preset-env": "^7.3.4",
    "acorn": "^6.1.1",
    "autoprefixer": "^7.1.2",
    "babel-eslint": "^8.2.1",
    "babel-helper-vue-jsx-merge-props": "^2.0.3",
    "babel-loader": "^8.0.5",
    "babel-plugin-syntax-jsx": "^6.18.0",
    "babel-plugin-transform-runtime": "^6.22.0",
    "babel-plugin-transform-vue-jsx": "^3.5.0",
    "babel-preset-env": "^1.3.2",
    "babel-preset-stage-2": "^6.22.0",
    "chalk": "^2.0.1",
    "copy-webpack-plugin": "^4.0.1",
    "css-loader": "^0.28.0",

.babelrc

{
  "presets": [
    ["@babel/preset-env", {
      "modules": false,
      "targets": {
        "browsers": ["> 1%", "last 2 versions", "not ie <= 8"]
      }
    }],
    "stage-2"
  ],
  "plugins": ["transform-vue-jsx", "transform-runtime"]
}
