Question

直到今天，我一直在使用django完全没有问题。它给了我一个现有项目的错误，但我最近尝试创建一个新项目，我仍然得到相同的错误。我在ubuntu 14.04，django 1.7，我使用virtualenv和python 3（尽管我也尝试过使用python2 env）。

我收到此错误：

ubuntuuser@computer:~/tmp$ 
ubuntuuser@computer:~/tmp$ mkvirtualenv djerror

cd (djerror)ubuntuuser@computer:~/tmp$ cd borrar/

djerror  manage.py

    from repr import *
ImportError: No module named 'repr'

这是另一种给我带来同样错误的方法：

ubuntuuser@computer:~/tmp$ virtualenv djerror2

ubuntuuser@computer:~/tmp$ cd djerror
ubuntuuser@computer:~/tmp/djerror$ cd ..

(djerror2)ubuntuuser@computer:~/tmp/djerror2$ django-admin.py startproject anothertest
(djerror2)ubuntuuser@computer:~/tmp/djerror2$ cd anothertest/
(djerror2)ubuntuuser@computer:~/tmp/djerror2/anothertest$ python manage.py runserver
Traceback (most recent call last):
  File "manage.py", line 8, in <module>

    import collections
  File "/usr/local/lib/python3.4/collections/__init__.py", line 17, in <module>
    from reprlib import recursive_repr as _recursive_repr
  File "/usr/local/lib/python2.7/dist-packages/reprlib.py", line 3, in <module>
    from repr import *
ImportError: No module named 'repr'
(djerror2)ubuntuuser@computer:~/tmp/djerror2/anothertest$

是什么给出了？

编辑：

这就是我在〜/ .bashrc底部的内容。自从我安装ubuntu以来，我做了一些更改，但最近我更改了virtualenvwrapper的底部两行。

alias python='python3'

export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh

我认为文件的其余部分未受影响。

Answer 1

经过一番摆弄（特别是在读完布兰登和丹尼尔的评论之后），我发现了这个问题。

我在某个时间点做错了什么，直到今天才引起问题。问题是python正在从python2路径加载一些模块，而其他模块从python3路径加载。

为了解决这个问题，我做了以下几点：

删除python3别名
- 要正确执行此操作，您必须从/ usr / bin /获取rm python，然后将其指向python3 sim链接
清除删除python3并重新安装。
重新安装与python3相关的所有软件包，如pip和其他

只有这样才能完成所有工作，虽然我可能已经过火了，但我更喜欢这样做，只是为了确定。
