/usr/bin/python3: Error while finding spec for 'virtualenvwrapper.hook_loader' (: No module named 'virtualenvwrapper')

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

Answer 1

On my computer, I ran sudo apt install python-pip and then pip install virtualenvwrapper but on my settings, I set it as follows:

export WORKON_HOME=$HOME/.Envs
export VIRTUALENVWRAPPER_PYTHON=$(which -a python3)
source $HOME/.local/bin/virtualenvwrapper.sh

That got rid of the error and note that I am using python3 and I use pip3 as my default

Answer 2

I faced similar problem, when using python3 with virtualenvwrapper,

sudo apt-get install python3-pip

Then install virtualenv and virtualenvwrapper from pip3,

sudo pip3 install virtualenv virtualenvwrapper

then source it again,

source $HOME/.bashrc 

Answer 3

Thanks to @Alexander, I was able to fix my issue by changing the line in ~/.bashrc:

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3

to

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python

due to backwards compatibility.

Answer 4

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

Answer 5

check your python3 installation directory:

which python3

If installed by brew you should get:

/usr/local/python3

export python version to be used virtualenvwrapper:

export VIRTUALENVWRAPPER_PYTHON=/usr/local/python3

source your shell configuration file:
bash

source .bashrc

zsh

source .zshrc

Answer 6

I've got this error for entirely different reasons, but since I ended up on this thread, I gather somebody might find this useful. So in my case, it turned out that my script was attempting to activate the virtual environment while I was already on it (the workon statement is issued from my .profile file). And so the solution was to simply deactivate the environment first and then run the script.
