当我运行msbuild来构建一个vc2010项目时,我收到以下错误:

error MSB4019: The imported project "C:\Microsoft.Cpp.Default.props" was not found. 
Confirm that the path in the <Import> declaration is correct, and that the file exists 
on disk.

• msbuild位于c:\ Program File(x86)\ MSBuild
• HKLM\SOFTWARE\Wow6432Node\Microsoft\MSBuild\ToolVersions\V4.0 VCTargetsPath设置为$(MSBuildExtensionsPath32)\ Microsoft.Cpp\v4.0 \
• 运行msbuild/verbosity时:diag作为良好的系统显示MSBuildExtensionsPath32,MSBuildExtensionsPath64,MSBuildExtensionsPath 在构建开始时设置为Environment
• 将MSBuildExtensionsPath32,MSBuildExtensionsPath64,MSBuildExtensionsPath设置为shell中的环境变量不会导致它们在构建开始时显示为Environment

修复已尝试

• 卸载.net 4.5,修复.net 4.0
• 在系统变量中设置MSBuildExtensionsPath32,MSBuildExtensionsPath64,MSBuildExtensionsPath.

似乎没有正确设置MSBuildExtensionsPath32并且设置MSBuildExtensionsPath没有帮助

SET MSBuildExtensionsPath="C:\Program Files\MSBuild"

如果您有任何想法阻止正确设置此变量,请告诉我.

我正试图从我的桌面启动Visual Studio 2010,我只是弹出这个错误框说"未知错误"...

任何人都知道为什么会发生这种情况？
