You need to install pandaswith:

您需要安装pandas：

pip install pandas

pip install pandas

If you run into issues with privileges, you may need to run:

如果您遇到权限问题，您可能需要运行：

sudo pip install pandas

sudo pip install pandas

It is also possible on Python 3 that you may need to run:

您也可能需要在 Python 3 上运行：

pip3 install pandas(although pipmay be pointing to pip3already). You can read about differences between pip versions on this SO post.

pip3 install pandas（虽然pip可能pip3已经指向）。您可以在此 SO post上阅读 pip 版本之间的差异。

If you don't have pipinstalled, see herefor installation.

如果您还没有pip安装，请参阅此处进行安装。

Check pandas package path from your env with:
jupyter kernelspec list

从您的 env 中检查 pandas 包路径：
jupyter kernelspec list

If you see the path: /Users/yourname/Library/Jupyter/kernels/yourenv

如果您看到路径： /Users/yourname/Library/Jupyter/kernels/yourenv

Delete that Jupyterfolder from Libraryand run again.

Jupyter从中删除该文件夹Library并再次运行。

if you see such thisin your IDE and the error "no module named pandas" when you run your code, it means that pandas has not been installed although you have done "pip install pandas" or whatever.

如果您在 IDE 中看到这样的信息，并且在运行代码时出现错误“没有名为 pandas 的模块”，则意味着尽管您已经完成了“pip install pandas”或其他任何操作，但尚未安装 pandas。

Go to file > settings > project interpreterand see if pandas is available in the list of packages. if not simply click + (plus), choose pandas and install it in your project environment .
see picturethen wait for you IDE update your project skeletons ... voila , the error disappears !

转到文件 > 设置 > 项目解释器，然后查看包列表中是否有 pandas 可用。如果不是简单地单击 +（加号），请选择 pandas 并将其安装在您的项目环境中。
看图片然后等你 IDE 更新你的项目骨架......瞧，错误消失了！

When entering the command to run your file, make sure you specify which version of python you're using. For example, instead of python filename.py, use python3 filename.pyor python2 filename.py

输入命令以运行文件时，请确保指定您使用的 Python 版本。例如，代替 python filename.py，使用python3 filename.py或python2 filename.py

your pandas is installed in python3 (3.7):

您的Pandas安装在 python3 (3.7) 中：

Requirement already satisfied: pandas in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (0.24.0)

but you are running python2.7 and pandas isn't in your path 2.7:

但是您正在运行 python2.7 并且 Pandas 不在您的路径 2.7 中：

['/Users/thibaultmonsel/Desktop/ML_folder', 
'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip', 
'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7', 
'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', 
'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', 
'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', 
'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', 
'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old', 
'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', 
'/Library/Python/2.7/site-packages', 
'/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python', 
'/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC']

try to simply run your script using python3:

尝试使用 python3 简单地运行您的脚本：

python3 help1.py

or add python3 header, example:

或添加 python3 标头，例如：

#!/usr/bin/env python3

or 

#!/usr/local/bin/python3

and if that doesn't work (like I had the same problem because I was importing pandas from jupyter notebook, macos), you can ultimately import from your --user path, example:

如果这不起作用（就像我遇到了同样的问题，因为我从 jupyter notebook、macos 导入Pandas），您最终可以从您的 --user 路径导入，例如：

sys.path.append("/Users/<USER>/Library/Python/3.7/lib/python/site-packages")

but make sure you have pandas installed there (..python/site-packages/pandas) using

但请确保您在那里安装了Pandas (..python/site-packages/pandas) 使用

pip3 install pandas --user

pip3 安装Pandas --user
