我想将我的django应用程序从sqlite移植到mysql.
但是当我尝试安装mysql-python时,它给了我这个错误:错误:命令'/ usr/bin/clang'失败,退出状态为1
我环顾四周寻找线索并尝试了这个似乎适用于大多数人的解决方案:
sudo su export CFLAGS = -Qunused-arguments export CPPFLAGS = -Qunused-arguments pip install MySQL-python

我收到此错误:

我正在开发一个托管在 Heroku 上的 Django 应用程序。我可以使用我的用户名和密码登录到管理员。但是在每次单击（或几秒钟后的每次单击）时，它都会将我再次重定向到登录页面，并?next=/admin/model添加到 url。事实上，有时它会在让我查看管理控制台之前多次要求登录。此行为不会反映在本地部署中。管理员在本地工作得很好。
我尝试了这里提到的建议：https : //docs.djangoproject.com/en/1.8/faq/admin/#i-can-t-log-in-when-i-enter-a-valid-username-and- password-it-just-brings-up-the-login-page-again-with-no-error-messages。但这无济于事。
任何线索我可能做错了什么？
