通过MSBuild构建Visual Studio 2015 C ++项目（v140）失败-无法找到v140

我同时安装了Visual Studio 2013和2015。我刚刚将组合解决方案（C＃，C ++，C ++ / CLI）升级到了2015年，并将Platform Toolset设置为v140。

从Visual Studio生成的工作正常，但不能从MSBuild进行编译。我使用MSBuild 14，MSBuild抱怨找不到v140，但这是无稽之谈，因为在计算机“ c：\ Program Files（x86）\ MSBuild \ Microsoft.Cpp \ v4.0 \ V140”中安装了v140。

无法完成有关升级解决方案的建议，因为解决方案已经升级，并且解决方案上下文菜单中没有此类项目。

如果我将项目的平台工具切换到v120，则可以使用。

更新：

• 从Debug X86跳过了一些项目。这是故意的。
• 该项目最初是在VS2008中创建的，然后升级到VS2013，然后升级到VS2015。
• 此计算机上安装了两个Visual Studio（2013社区和2015社区）。首先安装2013，之后安装2015。

注册表设置如下所示：

UPDATE2： 最小，完整和可验证的示例

我在Visual Studio 2015中创建了空的C ++控制台应用程序：

https://dl.dropboxusercontent.com/u/53387801/ConsoleApplication_v140.zip

#include "stdafx.h"

int main()
{
    return 0;
}

我可以在Visual Studio中构建它，但是在MSBuild中会遇到相同的问题：

解决了：

环境变量VisualStudioVersion设置为12.0而不是14.0将该值更改为14.0解决了该问题。

The simple console application started to work immediately after the Environment variable VisualStudioVersion changed and after windows logout, login.

The original project still couldn't be build after changing environment variable VisualStudioVersion. A retarget solution context menu appeared in Visual Studio 2015. So I retarget the solution. After retargeting the solution still couldn't be compiled (v140 not found). Finally I changed the platform toolset from v140 (not installed) to Visual Studio 2015 (v140). Now the solution can be compiled from Visual Studio and MSBuild as well.
