Ubuntu1804python install mysqlclient module error solution

Today, I installed the python module on ubuntu1804, mysqlclient reported an error, and recorded the solution

What is mysqlclient

1. mysqlclient is a database driver for python to connect to MySQL, written in c language.
2. Python also has a pymysql that is also connected to mysql data. These two modules are the same author. Why should I write two?
3. Comparison of advantages and disadvantages of pymysql and mysqlclient
   • One, pymysql
     • 1) Realized by pure Python, simple installation (direct pip installation)
     • 2) Due to the pure Python implementation, it can be well combined with the gevent framework
   • Second, mysqlclient
     • 1) It is a C extension module, compilation and installation may lead to various errors, obviously not convenient for pymysql
     • 2) Fast speed; database driver recommended by python3
   • 3. Current status
     • Because of the trouble, there are more domestic pymysql.
     • The problem that gevent cannot use mysqlclient, it is also said that you can use mysqlclient through gevent.hub
     • Django is recommended to use mysqlclient, to maintain high efficiency

Error review

Installing mysqlclient under ubuntu really gave an error.

python3 -m pip install mysqlclient

The error content is as follows: EnvironmentError: mysql_config not found

Resolve errors

1. Install missing libraries

sudo apt install libmysqlclient-dev
#centos下面使用，yum -y install mysql-devel 

Then go back and install it.

2. Direct apt installation When
   apt installation, automatically install related dependent packages

#Debian and Ubuntu use it to provide both python-mysqldb andpython3-mysqldb packages.
sudo apt install python-mysqldb    #python2
sudo apt install python3-mysqldb    #python3
