我正在尝试将我的角度模块导出为单独的 npm 模块。

所以我试图用 npm ( "packagr": "ng-packagr -p ng-package.json"

一切顺利，直到“编译到 FESM15”：

我在下面粘贴日志：


ng-packagr -p ng-package.json

在我的 package.json 下面：

}

不知道为什么该软件包不想构建。当我正常构建模块（npm run build）或什至用于生产（npm run build -- --prod）时，一切似乎都可以正常工作。

谢谢。

我遇到过同样的问题。我通过将错误中提到的模块添加到ng-package.json. IE：

{
  "$schema": "./node_modules/ng-packagr/ng-package.schema.json",
  "lib": {
    "entryFile": "public_api.ts",
    "externals": {
        "jsdom": "jsdom",
        "tough-cookie": "tough-cookie"
        // etc (or maybe you can localize the module that is using
        // them and use that module instead)
    }
  }
}
