我正在尝试在Windows环境中安装face_recognition，但在尝试安装dlib时显示错误。因此，我尝试使用
从命令提示符单独安装dlibpip install dlib
但它再次显示以下错误。我已经安装了cmake和boost但没有任何反应。

CMake Error at CMakeLists.txt:43 (message):
You have to use a version of Visual Studio that supports C++11. As of
December 2017, the only versions that have good enough C++11 support to
compile the dlib Pyhton API is a fully updated Visual Studio 2015 or a
fully updated Visual Studio 2017. Older versions of either of these
compilers have bad C++11 support and will fail to compile the Python
extension. ***SO UPDATE YOUR VISUAL STUDIO TO MAKE THIS ERROR GO AWAY***

好的，我只是通过更新Visual Studio找到了解决方案。早期的构建没有完整的C ++ 11支持，因此通过更新它，dlib被编译而没有任何错误。

所有您需要做的就是打开命令提示符，然后键入pip install dlib。如果这对您不起作用，请重新安装python，然后单击“环境变量”。这可能会解决问题。如果继续，请不要犹豫。
