pymysql停止工作:NameError:未定义名称"byte2int"

Question

我在Python中使用pymysql连接到数据库.它工作正常,但现在我得到了以下error:

Traceback(最近一次调用最后一次):

  File "/Users/njethani/Desktop/venv/lib/python3.6/site-packages/pymysql/__init__.py", line 94, in Connect
    return Connection(*args, **kwargs)

  File "/Users/njethani/Desktop/venv/lib/python3.6/site-packages/pymysql/_auth.py", line 72, in scramble_old_password
    hash_pass = _hash_password_323(password)

    for c in [byte2int(x) for x in password if x not in (' ', '\t', 32, 9)]:

    for c in [byte2int(x) for x in password if x not in (' ', '\t', 32, 9)]:
NameError: name 'byte2int' is not defined

我使用以下行连接到我的数据库(连接字符串):

conn = pymysql.Connect(host='hostname', port=3306, user='username', passwd='password', db='mysql')

Answer 1

由于 pymysql 维护者拒绝发布修复程序，解决方案只是安装旧版本的软件包：

pip3 install --user 'pymysql<0.9'

Answer 2

我遇到了同样的错误，看起来 _auth.py 无法找到 byte2int 的引用。我添加了以下行来修改 _auth.py 以使其正常工作。

从 util 导入 byte2int,int2byte

请注意 util.py 是 pymysql 的，因为其他包中也会有 util.py 文件。
