Plugins 安装ckanext viewhelpers时发生PluginNotFoundException

我使用CKAN作为我的开放式数据门户，并尝试按照中的说明安装ckanext viewhelpers扩展

但是，在我的CKAN配置文件中添加ViewHelper后，我无法解决这个错误

    paster serve /etc/ckan/default/development.ini

我在安装其他扩展时也遇到了同样的PluginNotFoundException，尽管根据文档，我在virtualenv上安装了扩展并将其添加到配置文件中。如果有人能帮我解决问题，我将不胜感激。谢谢。

我认为：

您在安装插件时没有激活virtualenv，或者

当您使用粘贴服务运行CKAN时，您的VirtualNV未激活

如果为1，请激活virtualenv并重新安装插件

---

如果是2，请激活您的虚拟电视。

嗨，肖恩，谢谢您的回复。我已经更新了我在问题中遇到的错误。这是一个PluginNotFoundException:viewhelpers。我在安装其他扩展时也遇到了同样的错误，尽管我严格遵循了文档。希望你能告诉我我做错了什么。谢谢谢谢但同样的错误仍然存在。我不知道为什么。
