ckan.plugins.core.PluginNotFoundException：pdf_view错误

问题描述

我在Ubuntu 16.04上从软件包中安装了CKAN 2.8.5。我激活了ckanext-pdfview。一切都好。但是，当我运行粘贴程序命令时，收到以下错误。

Traceback (most recent call last):

ckan.plugins.core.PluginNotFoundException: pdf_view

解决方法

我找到了解决方案。当我进入虚拟环境时，我运行带路径的pip命令。首先，我在虚拟环境中找到了pip命令所使用的路径，然后运行带有path的pip命令。
