Issue installing Virtualenvwrapper on Ubuntu 18.04?

问题

Fresh Ubuntu 18.04 install. Following these instructions here are the commands I've run so far.

sudo apt update
sudo apt upgrade
python3 -V 
sudo apt install python3-pip
sudo apt install build-essential libssl-dev libffi-dev python3-dev
sudo apt install python3-venv
source /usr/local/bin/virtualenvwrapper.sh

Returns

bash: /usr/local/bin/virtualenvwrapper.sh: No such file or directory.

find virtualenvwrapper.sh

Returns

find: ‘virtualenvwrapper.sh’: No such file or directory

EDIT:

Sudo -H pip3 install virtualenv virtualenvwrapper

didn't solve the issue either.

I found this solution that sovled the issue.

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3

then make sure to install virtualenv and virtualenvwrapper with:

sudo /usr/local/bin/pip3 install virtualenv virtualenvwrapper

You may have to use sudo's -H flag like I did for it to work.

回答1:

You've installed python3, pip and venv but not virtualenvwrapper. Install it with pip:

pip install virtualenvwrapper

回答2:

on Ubuntu 18.04 I had to add this to my .bash_profile

# virtualenv and virtualenvwrapper
export WORKON_HOME=$HOME/.virtualenv
export VIRTUALENVWRAPPER_LOG_DIR="$WORKON_HOME"
export VIRTUALENVWRAPPER_HOOK_DIR="$WORKON_HOME"
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
source ~/.local/bin/virtualenvwrapper.sh

Then run source ~/.bash_profile

This is what worked for me:

Purge and reinstall pip first.

sudo apt-get purge python-pip
sudo apt-get update
sudo apt-get install python-pip

Then install virtualenvwrapper:

sudo pip install virtualenvwrapper
