python - 在 virtualenv 中运行的 django 在执行/usr/share/qgis... 后给出语法错误(不在 virtualenv 中)

Question

我正在使用 virtualenv 运行 django。由于某种原因，django 在 /usr/share/qgis/python/httplib2... 中调用 httplib2 ，由于某种原因存在语法错误。在我从 arch 的 AUR 安装 qgis 库之前，这种情况从未发生过。

我不明白为什么它要调用qgis中的库？我在 virtualenv 和文件系统上都有相同的库(在弹出错误后安装):

[root@arch http]# pacman -Ql | grep httplib2
...
python-httplib2 /usr/lib/python3.4/site-packages/httplib2/
...

这是有关我的 virtualenv 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 pip 长，我认为最有趣的是最后几行(堆栈的顶部)。它说 django 尝试使用 /usr/share/qgis...

中的库

那么我该如何解决呢？如何让 python 执行 virtualenv 中的 httplib2？

预先感谢您的时间和善意帮助。

编辑 1:来自 virtualenv 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', 
 '/srv/http/merging_map_/app/lib/python3.4', 
 '/srv/http/merging_map_/app/lib/python3.4/plat-linux', 
 '/srv/http/merging_map_/app/lib/python3.4/lib-dynload', 
 '/usr/lib64/python3.4', '/usr/lib/python3.4', 
 '/usr/lib/python3.4/plat-linux', 
 '/srv/http/merging_map_/app/lib/python3.4/site-packages']

我不知道 qgis 文件夹到底是如何进入 virtualenv exec 路径的。请告诉我如何把它弄出来!!以及如何将其替换为正确的 python 路径。

所以问题似乎是该库位于 PYTHONPATH 中。您只需执行即可将其删除

$ unset PYTHONPATH
$ source /path/to/venv/bin/activate

现在关于它是如何到达那里的:可能您安装了一些东西(QGIS)将其添加到那里。您可以尝试在定义它的地方找到它并将其删除

$ grep -r "PYTHONPATH" /etc

此外，您还应该 checkin 主文件夹中的 .bashrc 和 .profile 文件。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......
