当安装pywin时遇到错误提示'python version 2.7 required,which was not found in the registry'，问题在于Python 2.7的路径未正确注册在系统注册表中。解决方案包括手动添加注册表项或运行Python脚本register.py，通过命令行执行'python register.py'来完成注册。" 81111071,7850730,MapReduce计算模型实战解析,"['大数据开发', 'MapReduce', '数据处理']

原因是安装Python时系统注册表没写一个PythonPath,具体路径如图：

这样再点开安装程序就能正常进行了，

如果嫌麻烦，可以写个.py文件：

    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()

保存至某个目录（如：D:\\register.py）,然后使用命令行进入D:\\,输入命令 python register.py 按Enter即可。
