我似乎不能导入Pandas包。我使用Visual Studio代码编码。我使用Mac电脑，并有osX 10.14 Majove。
我尝试编译的代码是：
import numpy as np
import matplotlib.pyplot as plt
import pandas as pd
house_data = pd.read_csv('house.csv')
plt.plot(house_data['surface'], house_data['loyer'], 'ro', markersize=4)
plt.show()当我尝试使用pip install pandas时，我在终端上看到：
(base) pip install pandas

Uninstalling pandas-0.24.0:
Successfully uninstalled pandas-0.24.0

最后，当我尝试pip3 install pandas时，我得到：

我还做了一个import.sys，如果有帮助的话：

您需要安装
pandas和：pip install pandas如果遇到权限问题，可能需要运行：
sudo pip install pandas在Python 3上也可能需要运行：
pip3 install pandas（尽管pip可能已经指向pip3）.您可以在this SO post上阅读pip版本之间的差异。如果您没有安装
pip，请参阅here进行安装。yws3nbqq2#
使用以下命令从您的环境中检查panda包路径：
jupyter kernelspec list如果看到路径：
/Users/yourname/Library/Jupyter/kernels/yourenv从
Library中删除该Jupyter文件夹，然后再次运行。gzjq41n43#
如果您在IDE中看到such this，并且在运行代码时看到错误“no module named panda”，则意味着尽管您已经执行了“pip install panda”或其他操作，但尚未安装panda。
转到文件〉设置〉项目解释器，看看包列表中是否有panda。如果没有，只需点击+（加号），选择panda并将其安装到您的项目环境中。
see picture然后等待您的IDE更新您的项目框架...瞧，错误消失了！

输入命令运行文件时，请确保指定所使用的python版本。例如，使用
python3 filename.py或python2 filename.py代替pythonfilename.pycgh8pdjw5#
你的Pandas安装在python3（3.7）：
但是你正在运行python2.7而Pandas不在你的路径上2.7：
尝试使用python3运行脚本：
或添加python3头文件，例如：
如果这不起作用（就像我从jupyter notebook，macos导入Pandas时遇到了同样的问题），你可以最终从你的--用户路径导入，例如：
但是要确保你在那里安装了panda（.. python/site-packages/panda）

检查您的虚拟环境（您可以在VS代码的左下角看到它）并在您的虚拟环境中安装软件包（例如panda），如下所示：

安装Pandas以外的项目，我想下载它只为一个env环境，但我得到了同样的错误，所以我这样做，从外面。
