 问题现象

  新安装python3.6版本后使用pip安装第三方模块失败，报错信息如下：

问题分析

  提示错误很明显报错的是PermissionError，应该是权限不足。查找了下资料，确认使用登录账号为普通用户，需要使用administrator权限运行cmd。提供一种简单易操作的方法以administrator权限执行cmd，如下

(1) 查找cmd运行绝对路径

C:\Users\shiyanan>where cmd
C:\Windows\System32\cmd.exe

(2) 到C:\Windows\System32目录下，右键单击cmd.exe文件以管理员身份运行。如下

可以发现路径名变成了C:\Windows\system32>

(3) 重新执行pip install lxml,结果如下

C:\Windows\system32>pip install lxml
Collecting lxml

(4) 结束
