/usr/bin/python3: Error while finding spec for 

Question

I'm trying to follow How To Serve Django Applications with uWSGI and Nginx on Ubuntu 14.04 and I'm failing at the very earlier stage, due to amount of output, I placed all related information into Pastebin.com - #1 paste tool since 2002!.

the actual error:

root@alexus:~# echo "source /usr/local/bin/virtualenvwrapper.sh" >> ~/.bashrc
root@alexus:~# source ~/.bashrc
/usr/bin/python3: Error while finding spec for 'virtualenvwrapper.hook_loader' (<class 'ImportError'>: No module named 'virtualenvwrapper')
virtualenvwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 and that PATH is
set properly.
root@alexus:~#

I'm following how to to the teeth, what am I doing wrong?

Answer 1

In macOS Sierra, If you installed virtualenv package using pip3, add following to .bash_profile

export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3

or

export VIRTUALENVWRAPPER_PYTHON=$(which python3)

after that every new virtualenvironment you created using workon myvenv uses python3 as python interpreter

Answer 2

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python

good choice, but you already knew /usr/bin/python is 2.7

If you want to use version 3

sudo apt-get install python3-pip

and logout & login
