【问题描述】：

我使用 anaconda 提示符安装了 pandas。 使用以下命令：-

pip install pandas

并得到以下消息：-

Requirement already satisfied: pandas in c:\users\maini_\anaconda3\lib\site-packages (1.0.3)
Requirement already satisfied: numpy>=1.13.3 in c:\users\maini_\anaconda3\lib\site-packages (from pandas) (1.18.1)
Requirement already satisfied: pytz>=2017.2 in c:\users\maini_\anaconda3\lib\site-packages (from pandas) (2020.1)
Requirement already satisfied: python-dateutil>=2.6.1 in c:\users\maini_\anaconda3\lib\site-packages (from pandas) (2.8.1)
Requirement already satisfied: six>=1.5 in c:\users\maini_\anaconda3\lib\site-packages (from python-dateutil>=2.6.1->pandas) (1.15.0)

但是当我使用以下命令将其导入 Jupiter 笔记本时：-

import pandas as pd

我收到以下错误：-

我也试过这个命令

python -m pip install pandas

并收到以下消息

请帮助我。提前谢谢你。

【问题讨论】：

在 Windows 计算机上的 anaconda 环境中安装 pandas 的最简单方法可以说是pip uninstall pandas，然后是conda install pandas。如果你正在使用带有 anaconda 的 notebook，我也可以推荐在 notebook 中使用%conda install <pkg-name>。

是的，它奏效了。谢谢！！

【参考方案1】：

由于你使用的是 Anaconda，最好的方法是使用 anaconda 提示符：

conda install pandas
