我刚刚在pycharm上下载了熊猫，就像通常下载模块一样。运行代码s=df.stack().sort_index(level=1).to_frame(0).T
s.columns=s.columns.map('{0[1]}{0[0]}'.format)
s
A0 A1 A2 B0 B1 B2
0 1 2 3 11 12 13
时，我仅收到以下错误
import pandas我也尝试过使用Traceback (most recent call last):

ImportError: cannot import name QUOTE_MINIMAL
将其安装在终端中，但后来我得到了：
pip install pandas可能是什么问题？我是熊猫的新手，但从来没有在pycharm上安装模块的问题。
