已安装模块时，获取flask-mysqldb的flask导入失败错误
提问于 2019-07-21 13:14:17
我试图从this教程中学习如何将flask与MySQL数据库链接起来。
我在我的虚拟环境中成功地安装了使用pip3的flask-mysqldb。
有一些答案，但他们都涵盖了fail to install flask-mysqldb，在我的情况下，安装本身是成功的，但我仍然在网页上得到错误。
当我使用flask run启动服务器并尝试将路由的URL localhost:5000/运行到浏览器中时，我收到了flask-mysqldb的导入错误。
这就是我得到的确切错误：
flask.cli.NoAppException: While importing "todo_app", an ImportError was raised:
File "/home/shubham/venv/lib/python3.6/site-packages/flask/cli.py", line 240, in locate_app

from . import _mysql
ImportError: libmysqlclient.so.18: cannot open shared object file: No such file or directory
During handling of the above exception, another exception occurred:

from . import _mysql
ImportError: libmysqlclient.so.18: cannot open shared object file: No such file or directoryvenv是python环境的名称
我不确定为什么会出现这个错误，因为我是在安装模块flask-mysqldb的相同python环境中运行服务器的。
另外，我在我的机器上安装了anaconda-navigator，命名为“base”的环境我尝试使用conda install flask-mysqldb安装模块，但没有显示模块错误。那么这个错误有没有可能是由于conda环境造成的呢？
请提出任何解决方案，从昨晚卡住了这一点。
编辑:我发现here安装MySQL-python应该可以解决这个问题，但我在安装MySQL-python时遇到了另一个错误

按相同的顺序尝试此操作
sudo apt install python3.6-dev libpython3.6-dev
sudo apt-get install mysql-server
virtualenv -p python3.6 venv
source venv/bin/activate
pip3 install flask
pip3 install flask-mysqldb然后创建app.py
from flask import Flask
app = Flask(__name__)
if __name__ == '__main__':
app.run()然后执行app模块
