Question

请帮我理解这一点。在这里你可以看到我已经设置了PYTHONPATH（它来自我的.bashrc）

jean@klippie:~$ echo $PYTHONPATH 
:/home/jean/local/lib/python2.6/site-packages

但是，如果我尝试在我的本地站点包中启动某些内容，则会被忽略：

jean@klippie:~$ gtimelog
Traceback (most recent call last):
  File "/home/jean/bin/gtimelog", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 2671, in <module>
    working_set.require(__requires__)
  File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 654, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 552, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: gtimelog==0.5.0

现在，如果我手动将PYTHONPATH导出到上面显示的值echo，则不会忽略它：

jean@klippie:~$ export PYTHONPATH=:/home/jean/local/lib/python2.6/site-packages
jean@klippie:~$ gtimelog
# SUCCESS

有什么问题？

最有可能的是，您只在PYTHONPATH中设置了shell变量.bashrc，但是您没有将此变量导出到环境中。通过echo打印仅显示shell变量具有打印值。尝试

env | grep PYTHONPATH

查询PYTHONPATH是否真的在环境中，并确保你export中确实.bashrc。

PYTHONPATH从环境中消失
