我想创建一个小型C ++库并使用Boost :: Python for Python接口。它应该支持两个版本的Python：2和3。
如this问题中所述，我在user-config.jam中创建了boost\tools\build\src文件，其内容如下：
using python : 2.7 : C:\\Python27amd64 ;
using python : 3.6 : "C:\\Program Files (x86)\\Microsoft Visual Studio\\Shared\\Python36_64" ;
然后我运行了bootstrap和.\b2 python=3.6,2.7。
我收到此错误：
C:/boost/tools/build/src/build\feature.jam:491: in feature.validate-value-string from module feature
error: "3.6" is not a known value of feature <python>
error: legal values: "2.7"
C:/boost/tools/build/src/build\property.jam:341: in validate1 from module property

C:\boost\tools\build\src/kernel/bootstrap.jam:139: in boost-build from module
C:\boost\boost-build.jam:17: in module scope from module
我该如何解决？
