我已经在一个Python 2.7项目中导入了MySQLdb，并创建了一个初始化函数来从数据库中获取数据，以验证传递给另一个函数的数据。下面的代码是我调用 init 时所破坏的：
def __init__(self, username, password):
print 'Initializing...'
self.db_conn = MySQLdb.connect(host="host", user=username, passwd=password, db = "db")
self.c = self.db_conn.cursor(MySQLdb.cursors.DictCursor)
self.make_map = self.getJsonMap('make')
self.model_map = self.getJsonMap('model')
self.color_map = self.getJsonMap('color')
self.getDBMakes()
self.getDBModels()
self.getDBColors()
我收到以下错误：
Traceback (most recent call last):
File "clean.py", line 114, in <module>
vc = ViolationCleaner('<user>', '<credential>')
File "/Users/taddeskorris/PP/Code/migration/import_violations/ViolationCleaner.py", line 53, in __init__
self.db_conn = MySQLdb.connect(host="host", user=username, passwd=password, db = "db")

遵循堆栈跟踪信息将导致源自包装的错误。我最近下载了MySQL社区服务器的另一个版本，并尝试对其进行调试。 MySQL版本为mysql Ver 8.0.16 for macos10.14 on x86_64 (MySQL Community Server - GPL)
我对MySQL软件包的PIP依赖关系是：
mysql 0.0.2
MySQL-python 1.2.5
mysqlclient 1.4.2.post1
无论我做什么，当我尝试运行需要MySQL连接的Python脚本时，都会遇到相同的错误。
