i trying understand why have issue when try install django-extensions. yet in virtualenv (wrapper) goat, didn't want install in it. how fix that?

update

with ls -ld on virtualenv, got 

drwxrwxr-x 7 jeremie jeremie 4096 sep  9 17:10 goat

this problem can occur of created virtualenv root.

if so, fix it, can run command:

sudo chown -r your_username:your_username path/to/virtuaelenv/

update

the other reason can occur when have installed pip (or pip3 in case) root.

from error can see trying install package outside of virtualenv, @ root level.

to verify this, check permissions of pip installation:

user@host:~$ pip3  /usr/local/bin/pip3 user@host:~$ ls -l /usr/local/bin/pip3 -rwxr-xr-x 1 root root ... etc, etc

or run one-liner:

ls -l `which pip3`

you can fix uninstalling pip3, , reinstalling without using sudo command.
