目前在使用python 3.7的macOS 10.15上，安装了MySQL 8.0.19。使用虚拟环境设置在VScode中进行开发。我也在phpmyadmin中创建了一个本地数据库。我想一直连接到它。脚本：
import pymysql
print("Before")
connection = pymysql.connect(host='localhost',
user='myUserName', password='myPassword', db='db_name', charset='utf8mb4',
cursorclass=pymysql.cursors.DictCursor)
print("After")
当我运行脚本时，执行将无限期挂起。打印“ After”之后，我必须退出执行。引用是：
Traceback (most recent call last):
File "connect.py", line 5, in <module>
user='myUserName', password='myPassword', db='db_name', charset='utf8mb4',

return self._sock.recv_into(b)
KeyboardInterrupt
不知道为什么会这样。这是怎么回事 我搜索了很多有关堆栈溢出的问题，但没有一个帮助我。
通过在pymysql connect函数中添加“ unix_socket”参数解决了问题。在此处查看答案：在此处输入链接说明
import pymysql
print("Before")
conn = pymysql.connect(db='w_dev', user='root', passwd='celebrate',
unix_socket="/tmp/mysql.sock")
print("After")
该脚本有效。
