Question

我有一个简单的nodejs字典应用程序，它使用webpack进行客户端模块管理和脚本连接。在我的本地机器上一切正常。现在我正在使用Azure中的CI进行一些实验。在使用来自visualstudio.com的CI的Azure连续交付选项的实验期间，我在执行webpack任务时遇到以下错误（我正在使用来自市场的webpack任务）。任何人都可以帮助我吗？

webpack构建任务特定的日志文件说：

以下是package.json

中的依赖项片段

"dependencies": {
    "async": "^2.5.0",
    "compression": "^1.7.0",
    "express": "^4.15.3",
    "inversify": "^4.2.0",
    "reflect-metadata": "^0.1.10",
    "request": "^2.81.0"
  },
  "devDependencies": {
    "@types/async": "^2.0.40",

    "jasmine-console-reporter": "^1.2.7",
    "typescript": "*",
    "typings": "^2.1.1",
    "webpack": "^3.0.0"
  }

可能有什么不对？

Answer 1

尝试安装reflect-metadata @types：https://www.npmjs.com/package/@types/reflect-metadata

npm i -D @types/reflect-metadata

也许你应该在tsconfig.json上添加它，取决于你当前的配置。

Answer 2

这更像是一个MS TFS问题。当我将Agent从“Hosted VS2017”更改为“Hosted Linux Preview”时，一切正常！

不确定幕后发生了什么。

Webpack在CI中返回错误 - TS2688：无法找到＆＃39; reflect-metadata＆＃39;
