Make sure that you're working with the version of Python that think you are. Within Python run
import sysandprint(sys.version).Select the correct package manager to install pymysql with:
- For Python 2.x
sudo pip install pymysql. - For Python 3.x
sudo pip3 install pymysql. - For either running on Anaconda:
sudo conda install pymysql. - If that didn't work try APT:
sudo apt-get install pymysql.
- For Python 2.x
If all else fails, install the package directly:
- Go to the PyMySQL pageand download the zip file.
- Then, via the terminal, cd to your Downloads folder and extract the folder.
- cd into the newly extracted folder.
- Install the setup.py file with:
sudo python3 setup.py install.
确保您使用的是您认为的 Python 版本。在 Python 中运行
import sys和print(sys.version).选择正确的包管理器来安装 pymysql：
- 对于 Python 2.x
sudo pip install pymysql。 - 对于 Python 3.x
sudo pip3 install pymysql。 - 有关蟒蛇处于运行：
sudo conda install pymysql。 - 如果这不起作用，请尝试 APT:
sudo apt-get install pymysql。
- 对于 Python 2.x
如果所有其他方法都失败，请直接安装软件包：
- 转到PyMySQL 页面并下载 zip 文件。
- 然后，通过终端，cd 到您的下载文件夹并解压缩该文件夹。
- cd 进入新解压的文件夹。
- 与安装setup.py文件：
sudo python3 setup.py install。

I had this same problem just now, and found the reason was my editor (Visual Studio Code) was running against the wrong instance of python; I had it set to run again python bundled with tensorflow, I changed it to my Anaconda python and it worked.
我刚才也遇到了同样的问题，发现原因是我的编辑器（Visual Studio Code）运行的是错误的 python 实例；我将它设置为再次运行与 tensorflow 捆绑在一起的 python，我将其更改为我的 Anaconda python 并且它起作用了。

I ran into the same problem earlier, but solved it in a way slightly different from what we have here. So, I thought I'd add my way as well. Hopefully, it will help someone!
我之前遇到过同样的问题，但解决的方法与我们这里的方法略有不同。所以，我想我也会添加我的方式。希望它会帮助某人！
sudo apt-get install mysql-clientdidn't work for me. However, I have Homebrew already installed. So, instead, I tried:
sudo apt-get install mysql-client对我不起作用。但是，我已经安装了 Homebrew。所以，相反，我尝试：
brew install mysql-client
Now, I don't get the error any more.
现在，我不再收到错误消息。
Good luck!
祝你好运！
