Eclipse / PyDev 运行 pyramid development.ini 问题 "pkg_resources.DistributionNotFound:

Question

我刚开始学习Pyramid框架，想在Eclipse里运行这个程序。

我的运行配置是：

主模块： /home/ben/env/bin/paster

程序参数： serve /home/ben/dev/python/pyramid/firstPyramid/first/development.ini

这个虚拟环境里的paster在命令行下可以正常运行development.ini。但是在Eclipse里运行时却出现了：

[Invalid file specified for console output: ]

我还在使用PyDev，并且设置了虚拟环境的Python解释器。

有没有人知道可能是什么问题呢？

这里有个截图：

我通过在pydev中修改PYTHONPATH的设置，让它也包含env/bin这个路径，解决了这个问题。
