python - 如何将来自 xampp 的 MYSql 用于 python 3？

Question

当我尝试使用命令“pip3 install mysqlclient”安装 MySQL 客户端时出现以下错误。

Complete output from command python setup.py egg_info:
    /bin/sh: mysql_config: command not found
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/private/var/folders/l1/f1klm_s92g53c9v2p1vrdwg80000gn/T/pip-install-a0t6svmj/mysqlclient/setup.py", line 18, in <module>
        metadata, options = get_config()
      File "/private/var/folders/l1/f1klm_s92g53c9v2p1vrdwg80000gn/T/pip-install-a0t6svmj/mysqlclient/setup_posix.py", line 53, in get_config
        libs = mysql_config("libs_r")

        raise EnvironmentError("%s not found" % (mysql_config.path,))
    OSError: mysql_config not found

XAMPP 版本：- 7.2.3.0 Python：- 3.7

谁能帮我解决这个错误？谢谢

要安装 MySQL-python 包，请键入以下命令：

pip install MySQL-python

要安装 mysql-connector-python 包，请键入以下命令：

pip install mysql-connector-python

要安装 pymysql 包，请键入以下命令：

pip install pymysql

代码示例

hostname = 'localhost'
username = 'USERNAME'
password = 'PASSWORD'
database = 'DBNAME'
def doQuery( conn ) :
cur = conn.cursor()

cur.execute( "SELECT fname, lname FROM employee" )
for firstname, lastname in cur.fetchall() :
    print firstname, lastname
print "Using MySQLdb…"
import MySQLdb
myConnection = MySQLdb.connect( host=hostname, user=username, passwd=password, db=database )
doQuery( myConnection )
myConnection.close()
print "Using pymysql…"
import pymysql
myConnection = pymysql.connect( host=hostname, user=username, passwd=password, db=database )
doQuery( myConnection )
myConnection.close()
print "Using mysql.connector…"
import mysql.connector
myConnection = mysql.connector.connect( host=hostname, user=username, passwd=password, db=database )
doQuery( myConnection )
myConnection.close()
