pip install pandas報錯如下信息：
ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.
網上有建議是如下兩天命令解決：
python -m pip install --upgrade pip
python -m pip install --upgrade setuptools
然後再重新安裝：
pip install pandas
顯示如下：
~]# python -m pip install --upgrade pip
