无法确定VS Common Tools文件夹的位置

Question

我有一个批处理文件，它调用MSBuild并构建三个Visual Studio解决方案：

call "C:Program Files (x86)Microsoft Visual Studio 10.0VCvcvarsall.bat"
MSBuild solution0.sln  /property:Configuration=Release
MSBuild solution1.sln  /property:Configuration=Release  
MSBuild solution2.sln  /property:Configuration=Release

这很好用。但是，我想提示用户选择要构建的程序的版本。根据用户输入，我们构建了一组特定的解决方案。

我的问题是，如果在调用vcvarsall之后修改PATH变量，我将无法再调用MSBuild。

call "C:Program Files (x86)Microsoft Visual Studio 10.0VCvcvarsall.bat"
set /P version="Enter the version number [1] or [2]:"
IF %version% == 1 (
    set PATH="%PATH%;%PATH_TO_VERSION1_LIBS%"
    MSBuild solution0_v1.sln  /property:Configuration=Release
    MSBuild solution1_v1.sln  /property:Configuration=Release   
    MSBuild solution2_v1.sln  /property:Configuration=Release
)
IF %version% == 2 (
    set PATH="%PATH%;%PATH_TO_VERSION2_LIBS%"
    MSBuild solution0_v2.sln  /property:Configuration=Release
    MSBuild solution1_v2.sln  /property:Configuration=Release   
    MSBuild solution2_v2.sln  /property:Configuration=Release
)

我得到以下错误：

Setting environment for using Microsoft Visual Studio 2010 x86 tools.
ERROR: Cannot determine the location of the VS Common Tools folder.

这是令人费解的，因为环境变量VS100COMNTOOLS是被定义的。

这可能是一个解析错误，请尝试：

IF "%version%"=="1" set "PATH=%PATH%;%PATH_TO_VERSION1_LIBS%"
IF "%version%"=="1" (
    MSBuild solution0_v1.sln  /property:Configuration=Release
    MSBuild solution1_v1.sln  /property:Configuration=Release   
    MSBuild solution2_v1.sln  /property:Configuration=Release
)
IF "%version%"=="2" set "PATH=%PATH%;%PATH_TO_VERSION2_LIBS%"
IF "%version%"=="2" (
    MSBuild solution0_v2.sln  /property:Configuration=Release
    MSBuild solution1_v2.sln  /property:Configuration=Release   
    MSBuild solution2_v2.sln  /property:Configuration=Release
)
