安装这个第三方库可能会遇到

Python version 2.7 required, which was not found in the registry

这个提示，一般python环境变量没设置好或者复制python包丢了registry文件导致的，最简单的办法是创建一个py文件（随便在什么位置），

然后运行下面的代码，再次安装就可以了！

import sysfrom _winreg import *# tweak as necessaryversion = sys.version[:3]installpath = sys.prefixregpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)installkey = "InstallPath"pythonkey = "PythonPath"pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (    installpath, installpath, installpath)def RegisterPy():    try:        reg = OpenKey(HKEY_CURRENT_USER, regpath)    except EnvironmentError as e:        try:            reg = CreateKey(HKEY_CURRENT_USER, regpath)            SetValue(reg, installkey, REG_SZ, installpath)            SetValue(reg, pythonkey, REG_SZ, pythonpath)            CloseKey(reg)        except:            print "*** Unable to register!"            return        print "--- Python", version, "is now registered!"        return    if (QueryValue(reg, installkey) == installpath and                QueryValue(reg, pythonkey) == pythonpath):        CloseKey(reg)        print "=== Python", version, "is already registered!"        return    CloseKey(reg)    print "*** Unable to register!"    print "*** You probably have another Python installation!"if __name__ == "__main__":    RegisterPy()
