windows下pip安装python模块时报错解决方法

1.使用pip安装python模块时报错如下
Exception:
Traceback (most recent call last):
File “C:\Program Files\Python36\lib\shutil.py”, line 544, in move
os.rename(src, real_dst)
PermissionError: [WinError 5] 拒绝访问。: ‘c:\program files\python36\lib\site-packages\pip-9.0.3.dist-info\description.rst’ -> ‘C:\Users\admin\AppData\Local\Temp\pip-w3lb4uc3-uninstall\program files\python36\lib\site-packages\pip-9.0.3.dist-info\description.rst’

During handling of the above exception, another exception occurred:

You are using pip version 9.0.3, however version 18.1 is available.
You should consider upgrading via the ‘python -m pip install --upgrade pip’ command.

2.该报错系权限问题
1 首先切换到c:\program files\目录下，
2 我们鼠标右击python35这个目录，点击 属性 ，
3 首先切换到 安全 这个大标题下面，选中当前登陆的用户，然后再点击编辑，编辑完以后不要忘记点击应用，

4.再次输入pip安装python模块完全没问题的。
