node.js - 创建 ionic 项目失败？

Question

当我要创建项目时发生此错误。

C:\Users\Tareque\Desktop\ionic apps\app\node_modules\node-sass\build\src\libsass.vcxproj(20,3): error MSB4019: The imported project "C:\Microsoft.Cpp.Default.props" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk.

 PS C:\Users\Tareque\Desktop\ionic apps> ionic start app blank
√ Creating directory .\app - done!
√ Downloading and extracting blank starter - done!

? Would you like to integrate your new app with Cordova to target native iOS and Android? Yes
√ Personalizing ionic.config.json and package.json - done!
> ionic integrations enable cordova --quiet
√ Downloading integration cordova - done!
√ Copying integrations files to project - done!
[OK] Added cordova integration!

Installing dependencies may take several minutes.

在错误开始发生后，我多次更改了环境变量。然后我安装 python 并设置环境变量并安装 Visual Studio 来解决 Windows 构建错误。现在一切正常..
