    import sys  
    
    from _winreg import *  
    
    # tweak as necessary   
    version = sys.version[:3]  
    installpath = sys.prefix  
    
    regpath = "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()  
  4. 双击执行 register.py

  5. 安装 pywin32-220.win-amd64-py2.7.exe

  6. 双击执行 get-pip.py
    打开命令行窗口,确认 pip 被正确安装:pip --version
