无法导入panda包解决方法

在试图使用panda包进行数据分析时，发现导入包失败，通过以下方法尝试后解决

报错代码：

PS D:\DEMO\MathorCup\test> python py.py Traceback (most recent call last): File "py.py", line 1, in <module> import pandas as pd ModuleNotFoundError: No module named 'pandas'

使用cmd输入 以下命令
pip install pandas -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

弹出错误
Could not install packages due to an EnvironmentError: [WinError 5] 拒绝访问。: 'c:\\program files\\python\\lib\\site-packages\\pip-10.0.1.dist-info\\entry_points.txt' Consider using the --user option or check the permissions.

命令最后加上 --user
pip install pandas -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com --user

安装成功
