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 issue is that pandasis not installed locally on your computer. Luckily, this is a simple task to accomplish by opening up either a Terminal or Command Prompt (depending on your OS), and typing in the command pip install pandas. This will install pandas and you will be good to go!
您的问题是pandas未在您的计算机上本地安装。幸运的是，这是一项简单的任务，只需打开终端或命令提示符（取决于您的操作系统），然后输入命令pip install pandas. 这将安装Pandas，你会很高兴！

The issue is that Anaconda installs a Python version of its own, and likely the Python version is Python 3. When you use PyCharm IDE as your editor, you are using another version of Python (Python2). For my Mac, Anaconda's Python is installed under /anaconda3/binand my default Python is installed under /usr/bin/python.
问题是 Anaconda 安装了自己的 Python 版本，并且 Python 版本可能是 Python 3。当您使用 PyCharm IDE 作为编辑器时，您正在使用另一个版本的 Python (Python2)。对于我的 Mac，Anaconda 的 Python/anaconda3/bin安装在/usr/bin/python.
I recommend you either config PyCharm to use Anaconda's Python, or use Anaconda's Jupyter your project. Jupyter is arguably a stronger tool considering that you are doing data analytics task.
我建议您将 PyCharm 配置为使用 Anaconda 的 Python，或者在您的项目中使用 Anaconda 的 Jupyter。考虑到您正在执行数据分析任务，Jupyter 可以说是一个更强大的工具。
Also, for Anaconda's python, you shoud use conda install pandasinstead of pip install pandasto install additional packages. This is not necessary this time since it's already installed.
此外，对于 Anaconda 的 python，您应该使用conda install pandas而不是pip install pandas安装其他软件包。这次没有必要，因为它已经安装了。
