Answer 1

Don't use sudo use a virtual environment instead, like this:

$ sudo apt-get install python-virtualenv
$ mkvirtualenv django_env
$ source django_env/bin/activate
(django_env) $ pip install django
(django_env) $ cd $HOME
(django_env) $ mkdir projects
(django_env) $ cd projects
(django_env)/projects $ django-admin.py startproject foo
(django_env)/projects $ cd foo
(django_env)/projects/foo $ python manage.py runserver

When you are finished; type deactivate to exit the virtual environment:

(django_env)/projects/foo $ deactivate
/projects/foo $

试试sudo pip install django 。

Answer 3

The location which you are trying to install django "usr/local/lib/..." is root owanership location.So for every command you would require sudo.

Instead of that you can follow these stpes

1.Install vitrual environment

$ sudo pip install virtualenv

2.Create virtual env

$ virtualenv -p python3 testEnv 

(Dont use sudo here it will make the environment root ownership.Here i am creating python 3 environment)

3.Activate that env using following command

$ source testEnv/bin/activate

4. Install django using the command

$ pip install django

5.Using the follwing command you can check the installed packages in that environment

$ pip freeze

note:It is better to use pip commands without sudo.If we are using sudo that package will change to root ownership
