【Error】Win10/Python3.9安装dlib报错：subprocess.CalledProcessError以及解决方法

解决方案

报错显示vs2022的c++安装安装boost和cmake配置cmake环境变量之前尝试过的方法

注意python3.9就选择cp39的dlib包，否则报错：
ERROR: dlib-19.7.0-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform.

    You must use Visual Studio to build a python extension on windows.  If you
    are getting this error it means you have not installed Visual C++.  Note
    that there are many flavors of Visual Studio, like Visual Studio for C#
    development.  You need to install Visual Studio for C++.

显示 我没有安装Vc++，但是我已经安装好了

官网下载免费社区版，并且进入D盘cl命令后，确认已经安装
命令行找到cd D:vs2022VCToolsMSVC14.31.31103binHostx64x64>输入cl

显示这个就是安装好了

pip3 install boost

pip3 install cmake
经常报错在cmake但是我确实是安装ok了的 迷惑

确认一下：

只要在命令行输入cmake

这样应该也是安装好了的

在Path中加上D:vs2022Common7IDECommonExtensionsMicrosoftCMakeCMakebin

打开vs的x64的窗口


无事发生，依然报错，只是这次的报错换了一个子进程报错；
我这次是打算按照网上说的 下载dlib官网上的包然后找到setup
再用python setup.py install 也报错：

subprocess.CalledProcessError: Command ‘[‘cmake’, ‘D:python3.9dlib-19.23toolspython’, ‘-DCMAKE_LIBRARY_OUTPUT_DIRECTORY=D:python3.9dlib-19.23buildlib.win-amd64-3.9’, ‘-DPYTHON_EXECUTABLE=D:python3.9python.exe’, ‘-DCMAKE_LIBRARY_OUTPUT_DIRECTORY_RELEASE=D:python3.9dlib-19.23buildlib.win-amd64-3.9’, ‘-A’, ‘x64’]’ returned non-zero exit status 1.

题主初学者 到现在还是没能知道问题出在哪里 还请评论帮忙看一下~但是直接运行编译好的cp39包就可以成功安装啦

确认一下：

记一次Win10环境python3.7安装dlib模块趟过的坑.
