Question

我遇到以下错误：

./src/index.js中的
ERROR模块构建失败（来自 ./node_modules/babel-loader/lib/index.js）：ReferenceError：[BABEL] /home/pedro/Documents/workana/gobots-app/react-app-master/react-app-webpack-rollback/react-app-webpack/src/index.js：未知选项：.0。查看 https://babeljs.io/docs/en/babel-core/#options了解更多信息关于选项。在throwUnknownError（/ home / pedro / Documents / workana / gobots-app / react-app-master / react-app-webpack-rollback / react-app-webpack / node_modules / @ babel / core / lib / config / validation / options处.js：123：11）在Object.keys.forEach.key（/ home / pedro / Documents / workana / gobots-app / react-app-master / react-app-webpack-rollback / react-app-webpack / node_modules / @ babel / core / lib中/config/validation/options.js:107:5）在Array.forEach（）在validateNested（/ home / pedro / Documents / workana / gobots-app / react-app-master / react-app-webpack-rollback / react-app-webpack / node_modules / @ babel / core / lib / config / validation / options中.js：83：21）在验证时（/ home / pedro / Documents / workana / gobots-app / react-app-master / react-app-webpack-rollback / react-app-webpack / node_modules / @ babel / core / lib / config / validation / options .js：74：10）在实例化预设（/home/pedro/Documents/workana/gobots-app/react-app-master/react-app-webpack-rollback/react-app-webpack/node_modules/@babel/core/lib/config/full.js ：268：36）在cachedFunction（/home/pedro/Documents/workana/gobots-app/react-app-master/react-app-webpack-rollback/react-app-webpack/node_modules/@babel/core/lib/config/caching.js中：33：19）在loadPresetDescriptor（/home/pedro/Documents/workana/gobots-app/react-app-master/react-app-webpack-rollback/react-app-webpack/node_modules/@babel/core/lib/config/full.js中：257：18）在config.presets.reduce（/ home / pedro / Documents / workana / gobots-app / react-app-master / react-app-webpack-rollback / react-app-webpack / node_modules / @ babel / core / lib / config中/full.js:79:21）在Array.reduce（）

尝试以这种方式配置babel.rc时，请使用react：

{
  "presets": [
    [ "@babel/preset-env","es2015", "stage-0", {
      "modules": false,
      "targets": {
        "browsers": [
          "last 2 Chrome versions",
          "last 2 Firefox versions",
          "last 2 Safari versions",
          "last 2 iOS versions",
          "last 1 Android version",
          "last 1 ChromeAndroid version",
          "ie 11"
        ]
      }
    } ],
    "@babel/preset-react"
  ],
  "plugins": [ "@babel/plugin-proposal-class-properties" ]
}

我的原始babel.rc文件是：

{
  "presets": [
    [ "@babel/preset-env", {
      "modules": false,
      "targets": {
        "browsers": [
          "last 2 Chrome versions",
          "last 2 Firefox versions",
          "last 2 Safari versions",
          "last 2 iOS versions",
          "last 1 Android version",
          "last 1 ChromeAndroid version",
          "ie 11"
        ]
      }
    } ],
    "@babel/preset-react"
  ],
  "plugins": [ "@babel/plugin-proposal-class-properties" ]
}

我正在按照以下问题的答案来纠正我的React项目：regeneratorRuntime is not defined

有什么问题吗？

尝试配置babel.rc时出错-尝试配置预设参数
