python安装dlib模块出错

使用python -m pip install dlib
出错原因如下:
python -m pip install dlib

以前安装过python2和python3,现在已经把python3卸载了。
使用pip install XXX会出现错误,所以才用python -m pip install dlib

windows下安装dlib需要CMake, 需要一个C++编译器(g++, VS 都可以), 需要boost库,并且需要在环境变量path中添加这些东西.
然后就可以直接用pip安装 (或者进入到源码 py -2 setup.py install)了

主要麻烦在windows
很关键的一点是,像Python2和Python3是2个语言一样,dlib18和dlib19本身就是两个包。最简单的就是在python2的基础上装dlib18
装dlib18很简单,装Python2.7.15,然后用pip命令
pip install cmake==3.12.0 -i https://mirrors.ustc.edu.cn/pypi/web/simple
pip install boost==0.1 -i https://mirrors.ustc.edu.cn/pypi/web/simple
pip install opencv-python==3.4.2.17 -i https://mirrors.ustc.edu.cn/pypi/web/simple
pip install dlib==18.17.100 -i https://mirrors.ustc.edu.cn/pypi/web/simple

小白在努力中 您好,我用了您的命令成功装上了dlib,但是如果是安装最新的19.17.0版本的命令是怎么样的呢?因为我像安装一个人脸识别的库要省级到最新的版本,否则还是提示相面的错误信息

你需要先在系统上安装cmake
