当我通过在 .bash_profile 中添加“export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/”来解决运行python manage.py syncdb 时出现“找不到图像”的问题后。问题来自python manage.py runserver 有谁知道如何解决 OSError(Errno 20)？

【解决方案1】：

我刚刚意识到我同时安装了 mysql-python 和 mysql-connector-python 软件包。通过将数据库 'ENGINE' 设置从 'django.db.backends.mysql' 更改为 'mysql.connector.django'，问题就解决了。

在这里学到的教训：我可能应该使用 virtualenv 来尝试不同的 python 包。
