在执行“ npm install”时收到很多错误

• 问答

我正在使用Angular开发ASP.NET Core Web应用程序（我在Windows 10上安装了VS2019 Enterprise），它工作正常，并且一切正常，但是当我尝试将其发布到Azure App Service时。 npm i步骤中出现很多错误。

我尝试了所有可以找到的解决方案：

  • 安装 windows-build-tools
  • 更新Visual Studio并安装桌面构建工具
  • 安装 node-gyp
  • 修改node_modules中node-gyp的 configure.js
  • 卸载节点并重新安装最新版本

我仍然无法使其正常工作。

我得到的最新错误是：

我怀疑node-gyp有问题。从您的错误日志中，我可以看到该版本不是旧的[3.x]，您应该将其更新为最新版本。

如果您使用的是MacOS，则可以使用以下命令将node-gyp更新到最新版本：

$ [sudo] npm explore npm -g -- npm install node-gyp@latest

上面的sudo是可选的。仅在必要时使用它。

如果您使用的是Windows，则可以将node-gyp的版本更新为文档here之后的最新版本

如果这可以解决您的问题，并且您对node-gyp感到好奇，则可以随时阅读here

,

您可以尝试删除package-lock.json并重新启动body { background-image: url("https://www.rafflesmedicalgroup.com/images/default-source/default-album/wuhan-virus-background.jpg?sfvrsn=2"); background-size: cover; background-position: center; }
它对我有用，这要感谢https://github.com/sass/node-sass/issues/2773#issuecomment-559399501
