生产env时Angular4 webpack会出错,但在dev env

我正在使用Angular4和.Net Core Mvc开发应用程序。

当我在package.json中运行dev bundle脚本时,它可以工作。脚本如下:

del-cli wwwroot/dist/js/app && webpack --config webpack.config.dev.js --progress --profile --watch

当我在package.json中运行prod bundle脚本时,它会给出以下错误:

  

app.module.ngfactory.ts ...'承诺'仅指类型,但在此处用作值

Prod脚本如下:

del-cli wwwroot/dist/js/app && ngc -p tsconfig.aot.json && ngc -p tsconfig.aot.json && webpack --config webpack.config.prod.js --progress --profile --bail && del-cli 'wwwroot/dist/js/app/**/*.js' 'wwwroot/dist/js/app/**/*.js.map' '!wwwroot/dist/js/app/bundle.js' '!wwwroot/dist/js/app/*.chunk.js' 'ClientApp/app/**/*.ngfactory.ts' 'ClientApp/app/**/*.shim.ts' 'ClientApp/app/**/*.ngsummary.json' 'ClientApp/app/**/*.ngstyle.ts'

我的tsconfig.aot.json文件如下:

"compilerOptions": {
    "module": "es2015",
    "target": "es5",
    "lib": [
      "es2015",
      "dom"
    ],
    "moduleResolution": "node",
    "noImplicitAny": false,
    "sourceMap": false,
    "removeComments": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "outDir": "./wwwroot/dist/js/app"
  },
  "types": [ "node", "lodash", "core-js" ], 
  "typeRoots": [
    "node_modules/@types"
  ],
  "angularCompilerOptions": {
    "skipMetadataEmit": true
  }

我无法处理错误,我尝试了很多东西。我尝试将es2016,es2017添加到tsconfig中的lib部分但是没有用。

package.json中的@ types / core-js版本也是0.9.39。

"@types/core-js": "^0.9.39",
"@types/lodash": "^4.14.59",
"@types/node": "^6.0.45",
"typescript": "^2.2.2"

你能帮助我吗?

提前致谢

我想捆绑aot但正常的tsconfig文件会影响aot bundle。所以我准备了正常的tsconfig文件,如下所示,问题解决了:

{
  "compileOnSave": false,
  "compilerOptions": {
    "module": "commonjs",
    "target": "es5",
    "lib": [ "es2016", "dom" ],
    "moduleResolution": "node",
    "noImplicitAny": false,
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "skipLibCheck": true
  },
  "exclude": [
    "node_modules",
    "wwwroot/dist/js"
  ]
}
