安装pandas时我遇到的问题

一、命名问题
py的文件格式不能用pandas命名

二、

ERROR: THESE PACKAGES DO NOT MATCH THE HASHES FROM THE REQUIREMENTS FILE. If you have updated the package versions, please update the hashes. Otherwise, examine the package contents carefully; someone may have tampered with them.

这里我输入了

pip --default-timeout=1000 install pandas

于是乎

我成功了
