问题描述
我在MacOS上运行的是mysql@8.x版本,我已经用brew安装了mysql和mysql-connector-o.当前与mysql的brew链接.
I am running mysql@8.x version on my MacOS, I have installed mysql and mysql-connector-o with brew. Currently brew link with mysql.
在我的python3虚拟环境中运行Django项目时,我收到以下错误-
Running Django project on my python3 virtual env I am receiving following error -
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named 'MySQLdb'.
Did you install mysqlclient or MySQL-python?
并在使用pip安装mysqlclient时,出现以下错误
and on installing the mysqlclient using pip, I am reciving following error

推荐答案
jordanm 指出,问题是正是缺少的openssl库,我按照这些步骤解决了我的问题-
As jordanm pointed it out, the issue was exactly with the missing openssl libraries, for which I followed these steps to fix my issue -
-
安装openssl
Installing openssl
brew install openssl
现在
pip install mysqlclient
应该可以.
Now
pip install mysqlclient
should work.
如果没有,但仍然显示相同的错误library not found for -lssl
,您还可以尝试链接到brew的openssl:
If it doesn't and still shows the same error library not found for -lssl
, you could also try to link against brew's openssl:
env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip install mysqlclient
如果这仍然不起作用,则可能需要使用pip的--no-cache选项,例如
if this still does not work, you might need to use the --no-cache option of pip, e.g.
env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip --no-cache install mysqlclient
