我正在使用virtualenv运行django。由于某些原因，django在/usr/share/qgis/python/httplib2...中调用httplib2，因为某些原因有语法错误。在我从arch的AUR安装qgis库之前，这种情况从未发生过。
我不明白为什么要调用qgis中的库?我在virtualenv和文件系统(在错误弹出后安装)中也有相同的库:
[root@arch http]# pacman -Ql | grep httplib2
...
python-httplib2 /usr/lib/python3.4/site-packages/httplib2/
...
这是关于我的虚拟环境的信息:
(app)[jenia@arch merging_map_]$ python --version
Python 3.4.1
(app)[jenia@arch merging_map_]$ pip freeze
Django==1.6.5
Pillow==2.5.1
django-simple-captcha==0.4.2
gunicorn==18.0
httplib2==0.9 <-------------- I installed this after finding the error.
ipython==2.1.0
oauthlib==0.6.3
psycopg2==2.5.3
python-social-auth==0.1.26
python3-openid==3.0.4
requests==2.3.0
requests-oauthlib==0.3.1
six==1.7.3
这是回溯。它有点长，我认为最有趣的是最后几行(堆栈的顶部)。它说django试图使用一个库在/usr/share/qgis...

那么我该如何修复它呢?我如何使python执行在虚拟环境中的httplib2 ?
提前感谢你的时间和善意的帮助。

编辑1:来自虚拟环境的系统路径:
['', '/srv/http/merging_map_',
'/usr/share/qgis/python', <----------------------- how did this get here?!!!
'/srv/http/merging_map_/app/lib/python34.zip',

我不知道qgis文件夹是如何进入虚拟环境的执行路径的。请告诉我怎么把它弄出来!!以及如何用正确的python路径替换它
所以问题似乎是库在PYTHONPATH中。你可以通过
删除它$ unset PYTHONPATH
$ source /path/to/venv/bin/activate
现在关于它是如何到达那里的:可能你安装了一些东西(QGIS)将它添加到那里。你可以试着在它定义的地方找到它并删除它
$ grep -r "PYTHONPATH" /etc
你也应该检查你的.bashrc和.profile文件在你的主文件夹。当然，如果您从python路径中删除该条目，需要它的软件可能会停止工作…
