此修复程序位于https://github.com/angular/angular.io/pull/3233/commits/8e886fc2710acadd749139c2172519de254b849c

你必须修改webpack.common.js

答案 1 :(得分：2)

  1. 由于您正在使用Angular 2，因此您的案例中唯一可行的解​​决方案是将@types/jasmine版本冻结为2.5.41。

    请参阅：https://stackoverflow.com/a/42182400/3472184

  2. 此外，您似乎在tsconfig.json中没有 ES6 支持。

    请参阅：https://stackoverflow.com/a/38212418/3472184。请注意lib和target属性。

答案 2 :(得分：1)

  1. 将tsconfig.json移至./src folder。请参阅config/webpack.common.js第7行：

    options: {
  configFileName: helpers.root('src', 'tsconfig.json')
}

  2. 将tsconfig.json更改为：

    {
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": ["es2015", "dom"],
    "noImplicitAny": true,
    "suppressImplicitAnyIndexErrors": true,
    "types" : ["node"]
  }
}

答案 3 :(得分：0)

@ user2995358为您的TS1219：设置实验设备＆＃39;删除此警告的选项。

将tsconfig.json从root

移到src文件夹
