在搭建python基本环境后，安装pandas出现无法安装的情况，如下报错
pip install pandas -i https://pypi.tuna.tsinghua.edu.cn/simple

Complete output from command python setup.py egg_info:
Traceback (most recent call last):

ModuleNotFoundError: No module named 'numpy'
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-kn6n2nu5/pandas/这时如果根据提示安装缺少的包，可能会很慢，而且最后也无法安装所有需要的包，不是提示网络连接超市，就是安装时报告一些莫名其妙的错误。其实解决方法很简单，只要升级pip版本就可以直接安装pandas相应的所有包了，具体方法如下
pip install --upgrade pip -i https://pypi.tuna.tsinghua.edu.cn/simple
