Question

我正在尝试使用外部Ckan library来完成我的第一个python程序。我添加了库，它似乎正在工作，因为命令import ckanap并没有给我任何错误。但是当我尝试运行程序时，我收到此错误

pkg_resources.DistributionNotFound：ckanapi

完整的错误消息（如果需要）是这个

我在互联网上搜索过它，但错误并没有多大帮助，更不用说我是python的新手了。

顺便说一句，即使没有任何命令，我也会收到此错误，只需使用import语句

修改
输出命令python -c "import sys ; print( '\n'.join(sorted(sys.path)))"

我认为这是ckanapi的安装问题......

它似乎有很多依赖项：https://github.com/ckan/ckanapi/blob/master/requirements.txt

你是如何安装它的？你试过pip install ckanapi吗？

在外部lib上使用pydev的DistributionNotFound错误
