如何创建 CKAN example_theme - 它不起作用

Question

我正在按照 http://docs.ckan.org/en/ckan-2.6.2/theming/templates.html 的教程进行操作

当然，我安装了此版本2.6.2并成功完成了默认设置。

步骤6(当我运行命令来服务时：paster serve --reload/etc/ckan/default/development.ini

我收到以下错误：

导入错误：没有名为插件的模块

我看到很多人遇到同样的错误，一定是有原因的。 请参阅链接： https://github.com/ckan/ckan/issues/3146， ckan 2.3 添加example_template插件的问题

有人对此有解决方案吗？

提前致谢

Answer 1

问题是主 ckan 存储库也有一个 ckanext/example_theme(在其测试中使用(，并且它正在找到那个。那个在通常的地方没有 plugin.py，因此错误。

解决方案是使用与"example_theme"不同的名称。

有两种解决方案：

1. 若要转换现有扩展，需要重命名其"example_theme"目录，在安装程序.py entry_points中编辑其路径，然后再次运行python setup.py develop。

2. 升级到 CKAN 2.7.X(或更高版本(并再次重新创建扩展。如果扩展目录中有任何 .pyc 文件，请将其删除。重新启动 CKAN。
