Visual Studio 2017 errors on standard headers
我刚刚升级到 Visual Studio 2017 社区版，我无法加载标准 header 文件。我从各种 header 文件中收到 507 错误。以下是一些片段：

我在使用 Visual Studio 2015 社区版时从未遇到过这个问题。我是否缺少安装程序中的某些组件？任何帮助，将不胜感激。谢谢！
我通过安装 Windows Universal CRT SDK 组件消除了错误，该组件增加了对遗留 Windows SDK 的支持。您可以使用 Visual Studio 安装程序安装它：
如果问题依旧，你应该更换Visual Studio项目中的Target SDK：查看WindowsSDK版本是否为10.0.15063.0。
在：项目 -> 属性 -> 常规 -> Windows SDK 版本 -> select 10.0.15063.0.
然后errno.h和其他标准文件将被找到并编译。
如果以上回答没有解决问题，请检查WindowsSDK版本是否为10.0.15063.0.
项目 -> 属性 -> 常规 -> Windows SDK 版本 -> select 10.0.15063.0
在此之后重建解决方案。
我将 VS2017 从 15.2 版本升级到 15.8。对于 15.8 版，发生了以下情况：
项目 -> 属性 -> 常规 -> Windows SDK 版本 -> select 10.0.15063.0 不再适合我！我不得不将其更改为 10.0.17134.0，然后重新构建所有内容。升级后，没有进行此更改，我遇到了相同的头文件错误。
我会提交这个作为对其他答案之一的评论，但我还没有足够的声誉。
如果有人仍然坚持这个，我找到的最简单的解决方案是 "Retarget Solution"。
在我的例子中，项目是用 SDK 8.1 构建的，升级到 VS2017 带来了 SDK 10.0.xxx。
重定向解决方案：
项目->重定向解决方案->"Select whichever SDK you have installed"->确定
从那里您可以简单地 build/debug 您的解决方案。希望对你有帮助
如果您的单元测试项目的 C++ 版本与您要测试的项目不同，也可能会出现此问题。
示例：
- 明确启用 C++ 17 的 EXE
- 将 C++ 版本设置为“默认”的单元测试
解决方案：将单元测试也更改为 C++17。
如果安装 Windows 通用 CRT SDK 如已接受的答案中所述没有帮助。尝试检查一下：
如果目录 “C:\Program Files\Windows Kits”在您的系统上存在，请确保它包含“10/Include”和“10/Lib”子目录。如果没有，创建硬链接，选择出现在你的“C:\Program Files (x86)\Windows Kits
解释：
正如您从 C:\Program Files (x86)\Windows Kits\DesignTime\CommonConfiguration\Neutral\uCRT.props 中看到的，路径“C:\Program Files\Windows Kits”优于“C:\Program Files (x86)\Windows Kits”如果它存在！

我在使用 Visual Studio 2015 社区版时从未遇到过这个问题。我是否缺少安装程序中的某些组件？任何帮助，将不胜感激。谢谢！
我通过安装 Windows Universal CRT SDK 组件消除了错误，该组件增加了对遗留 Windows SDK 的支持。您可以使用 Visual Studio 安装程序安装它：
如果问题依旧，你应该更换Visual Studio项目中的Target SDK：查看WindowsSDK版本是否为10.0.15063.0。
在：项目 -> 属性 -> 常规 -> Windows SDK 版本 -> select 10.0.15063.0.
然后errno.h和其他标准文件将被找到并编译。
如果以上回答没有解决问题，请检查WindowsSDK版本是否为10.0.15063.0.
项目 -> 属性 -> 常规 -> Windows SDK 版本 -> select 10.0.15063.0
在此之后重建解决方案。
我将 VS2017 从 15.2 版本升级到 15.8。对于 15.8 版，发生了以下情况：
项目 -> 属性 -> 常规 -> Windows SDK 版本 -> select 10.0.15063.0 不再适合我！我不得不将其更改为 10.0.17134.0，然后重新构建所有内容。升级后，没有进行此更改，我遇到了相同的头文件错误。
我会提交这个作为对其他答案之一的评论，但我还没有足够的声誉。
如果有人仍然坚持这个，我找到的最简单的解决方案是 "Retarget Solution"。 在我的例子中，项目是用 SDK 8.1 构建的，升级到 VS2017 带来了 SDK 10.0.xxx。
重定向解决方案： 项目->重定向解决方案->"Select whichever SDK you have installed"->确定
从那里您可以简单地 build/debug 您的解决方案。希望对你有帮助
如果您的单元测试项目的 C++ 版本与您要测试的项目不同，也可能会出现此问题。
示例：
- 明确启用 C++ 17 的 EXE
- 将 C++ 版本设置为“默认”的单元测试
解决方案：将单元测试也更改为 C++17。
如果安装 Windows 通用 CRT SDK 如已接受的答案中所述没有帮助。尝试检查一下：
如果目录 “C:\Program Files\Windows Kits”在您的系统上存在，请确保它包含“10/Include”和“10/Lib”子目录。如果没有，创建硬链接，选择出现在你的“C:\Program Files (x86)\Windows Kits
解释： 正如您从 C:\Program Files (x86)\Windows Kits\DesignTime\CommonConfiguration\Neutral\uCRT.props 中看到的，路径“C:\Program Files\Windows Kits”优于“C:\Program Files (x86)\Windows Kits”如果它存在！
