Django TemplateSyntaxError：找不到模板库bootstrap3

Question

我是新手，我安装了django-bootstrap3。 V5.3.1 添加＆＃34; bootstrap3＆＃34;到我的设置文件中的INSTALLED_APPS参数， 并开始在我的模板中引用{％load bootstrap3％}。我也重新启动了django。但是，我得到错误：有谁知道我怎么解决这个问题？

Answer 1

请重新检查＆＃34; bootstrap3＆＃34;在你的INSTALLED_APPS中并重新启动django。只有在重新启动后才会添加新的模板标签。

Answer 2

在我的情况下，问题是文件系统权限。

我在CentOS 7上以普通用户身份运行，但Apache以守护程序模式运行：apache group：apache。执行pip install bootstrap3后，我忘记执行sudo chown -R :apache /srv/python，其中/srv/python/.../site-packages位于WSGIDaemonProcess中配置的python路径上。使新加载的站点包可以按组读取：apache并重新启动httpd修复了问题。
