c# - EPERM : Operation not permitted - NPM Angular 7 on IIS with backend . 网络核心 2.1

Question

大家好，我用 Visual Studio 2017 制作了一个 Angular 7 应用程序。所以我在 Windows 10 上使用 IIS 获得了 AWS 机器。

当我加载应用程序时，出现此错误:

AggregateException: One or more errors occurred. (One or more errors occurred. (The NPM script 'start' exited without indicating that the Angular CLI was listening for requests. The error output was: Error: EPERM: operation not permitted, mkdir 'C:\Windows\system32\config\systemprofile\AppData\Roaming\npm'

TypeError: Cannot read property 'get' of undefined

因此，带有iis错误的图像返回:

完整文本错误:

我已经在服务器上安装了最新的nodejs版本。我哪里错了？

尝试将您的环境设置为生产环境。我认为这与尝试进行 NPM 启动有关

<environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Production" />
