Pymysql无法导入python3

Question

我正在 debian 9 机器上从 GCP 安装 LAMP。 Default GCP Lamp settingshttps://cloud.google.com/solutions/web-hosting

我在尝试将 pymysql 导入项目时遇到一些依赖错误。我不完全理解错误，或者确切地说我错过了什么。这是我得到的错误：

    >>> import pymysql
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/philip_plachta/.local/lib/python3.5/site-packages/pymysql/__init__.py", line 59, in <module>
    from . import connections  # noqa: E402
  File "/home/philip_plachta/.local/lib/python3.5/site-packages/pymysql/connections.py", line 206
    ):

这是我目前安装的python包

~$ python3 -m pip list

Python3 import Error

以下是我尝试过的大致内容。它变得有点混乱，因为我尝试了很多东西并卸载了东西并重新安装了它们等等。我不反对从头开始，但如果我能从比我更有经验的人那里得到一点指导，我将不胜感激！

sudo apt-get install python3-pip
sudo apt-get install python3-pymysql    
sudo python3 -m pip install Pymysql
sudo python3 -m pip install mysql-connector-python

编辑/解决方案

snakecharmerb 提供了使用 sudo apt install python3-pymysql 的建议。这为我在 GCP Lamp Server 的新实例上修复了它。我无法（放弃）从事另一项工作。我假设我安装或卸载的东西像snakecharmerb所暗示的那样搞砸了，但是当我可以制作一个新服务器并从一开始就执行apt install python3-mysql时，我不值得花时间去尝试找到它。

谢谢。

编辑编辑 这是我在新服务器上遵循的过程，似乎为我正确设置了东西

FROM THE START:
(First Goal is to access mysql from my local machine)
    sudo apt update
    sudo apt install php7.4-mbstring -y
    
(Create a mysql user)
    sudo mysql -u root -p
    CREATE USER 'username'@'%.%.%.%' IDENTIFIED BY 'password';
    GRANT ALL PRIVILEGES ON *. * TO 'username'@'%.%.%.%';
    
(Open to the outside world)

    Also had to create an ingress rule to allow sql to be accessed (via firewall in gcp) on 0.0.0.0/0 on port 3306

(Then...)
    sudo apt update
    sudo apt list --upgradable
    sudo apt upgrade
    
(Second goal is to allow my scripts to run on the machine)
    sudo apt install python3-pip -y
    sudo apt install python3-pymysql -y
    sudo apt install python3-mysql.connector -y

在我的 Debian 9 机器上，sudo apt-get install pymysql 安装 PyMySQL （0.7.10）（根据 pip3 列表），它在 口译员。看起来你在本地安装了更高版本， 其中包含与 Python 3.5 不兼容的语法。 ID 建议卸载 ~/.local 中的版本并尝试使用 apt安装的版本

snakecharmerb 提供了使用 sudo apt install python3-pymysql 的建议。这为我在 GCP Lamp Server 的新实例上修复了它。我无法（放弃）从事另一项工作。我假设这对我来说是一件愚蠢的事情——我安装或卸载的东西把事情搞砸了，就像蛇怪暗示的那样，但是当我可以建立一个新服务器并做 'apt 时，我不值得花时间去尝试找到它从一开始就安装python3-mysql'。

谢谢。
