没有。没有帮助。 - user2995358

是的，问题出在tsconfig.json和webpack.common.js配置文件的位置上，正如Irfan Syed和Lamer所提到的。这是正确的，因为tsconfig.json的标准位置是根目录。按照链接修改了webpack.common.js，它运行得很好！谢谢。 - user2995358
我必须撤销那个拉取请求才能使我的工作。Typescript没有使用/找到tsconfig。按照Typescript文档中描述的添加configFileName选项后它才能工作。 - gwest7

有了以上68个错误都消失了！但是，我仍然得到以下警告： TS1219: <snip>设置“experimentalDecorators”选项以消除此警告。 我的tsconfig.json如下所示： ` { "compilerOptions": { "target": "es5", "module": "commonjs", "moduleResolution": "node", "sourceMap": true, "emitDecoratorMetadata": true, "experimentalDecorators": true, "lib": ["es5", "es2015.promise"], "noImplicitAny": true, "suppressImplicitAnyIndexErrors": true }, "include": [ "src/**/*.ts" ], "exclude": [ "node_modules" ] }` - user2995358

  1. Move the tsconfig.json to ./src folder. Please see config/webpack.common.js line 7:

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

  2. change tsconfig.json to:

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

@user2995358 针对您的TS1219警告，请将“experimentalDecorators”选项设置为删除此警告。

将tsconfig.json从根目录移动到src文件夹中
