windows 10 下pip install 报错【PermissionError: [WinError 32] 另一个程序正在使用此文件，进程无法访问。】
C:UsershaseePython36Libsite-packagespipcompat_init_.py
第75行改为 return s.decode('cp936')
原因：
编码问题，虽然py3统一用utf-8了。但win下的终端显示用的还是gbk编码。
CP936其实就是GBK，IBM在发明Code Page的时候将GBK放在第936页，所以叫CP936。
下载whl包后安装
下载对应python、tesseract版本的teserocr包：
https://github.com/simonflueckiger/tesserocr-windows_build/releases
pip install XXX.whl 安装下载包
