Install Python virtual environment in Ubuntu 18.04

For reference only for Python developers using Ubuntu 18.04

1. Install Ubuntu 18.04 virtual environment

sudo apt install virtualenv
sudo apt install virtualenvwrapper

After the installation is complete, go to the home directory and enter the ls -al command to check whether the .virtualenvs directory appears. If not, manually create the .virtualenvs directory.

2. Install the module that can support virtual environment in Python environment (I use Python 3.6 here)

pip3 install virtualenv
pip3 install virtualenvwrapper

3. Configure the virtual management directory

Enter the home directory, enter the command ls -al, find the .bashrc file, and modify the .bashrc file

Add two lines to the end of your .bashrc file:

export WORKON_HOME=$HOME/.virtualenvs
source /usr/share/virtualenvwrapper/virtualenvwrapper.sh

4. Enable the configuration file

source ~/.bashrc

5. Check whether a virtual environment can be created

Use the mkvirtualenv project name to create a virtual environment. If successful, it means that the Ubuntu 18.04 virtual environment has been successfully created.

PS: Let's take a look at Ubuntu 18.04 installation & creation of virtual environment

1. Install and configure the virtual environment

2. Add the following line to ~/.bashrc:

  export WORKON_HOME=$HOME/.virtualenvs
