我之前能够使用VS2013 CE的工具集使用SCons构建此项目 从那时到现在，我所做的就是安装然后卸载TDM-GCC，msys和MinGW。
之后，每当我尝试运行SCons时，都会收到此错误：
D:\Projects>cd xsngine/src
D:\Projects\xsngine\src>scons -Q
The system cannot find the path specified.
IOError: The system cannot find the path specified.

我还尝试在各种版本和32/64位重新安装Python + SCons + PyWin32，但没有配置有效。 我也尝试卸载然后重新安装VS2013 CE，没有运气。
什么可能导致SCons没有检测到任何工具？
如果我从该错误行打印出变量，它会显示唯一可用的工具是'default'和None
我的SConstruct可以找到here
编辑：使用SCONS_MSCOMMON_DEBUG设置运行SCons：
