我是新来的。在成功安装 ckan 后，当我使用一些 ckan 插件作为示例 ckan-basiccharts 时，我得到了 ValueError。经过一番研究，我知道它与网络资产有关。在 basicchart 文件夹中，我将 {%resource ....} 更改为 {%asset ..}

.html 文件中的 ckanext/basiccharts/theme/templates/basechart_view.html

但我仍然遇到同样的错误。谁能解释一下这个错误背后的逻辑以及摆脱这个错误的一些技巧？

要迁移到 webassets，您需要创建一个 assets 文件夹并将扩展文件.js和文件放在那里。.css此外，您需要在 应注册这些.js和文件的资产文件夹中创建 webassets.yml。.css此过程在此处和此处进行了描述。

但是您可以使用与当前 ckan 版本兼容的此版本的 ckanext-basiccharts。
