face_recognition是一個人臉識別庫。
1.C:\Users\xx\pip，新建文件pip.ini
2.文件里面輸入：
[global] index-url = https://pypi.tuna.tsinghua.edu.cn/simple [install] trusted-host=mirrors.aliyun.com 需要勾選c++那一項。
命令行輸入：
1.python -m pip install --upgrade pip
2.pip install cmake
3.pip install dlib
4.pip install face_recognition
1.pip install dlib出現：
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++. 說明沒有安裝Visual Studio
安裝vs2019，勾選c++那一項進行安裝即可解決。
2 . pip install dlib出現ERROR: CMake must be installed to build dlib
先進行pip install cmake再pip install dlib
mkdir ~/.pip // 創建隱藏的文件夾(注意用戶是root還是普通user) vim ~/.pip/pip.conf // 創建一個pip.conf文件 // 在pip.conf中粘貼進下面內容(豆瓣源) [global] index-url = http://pypi.douban.com/simple [install] trusted-host=pypi.douban.com // wq保存一下就行了 然后終端輸入：
