Create a virtual environment using venv in python3 in Ubuntu

1. Virtual environment follows the project, create a virtual environment for a single project

(Python 3.4 and above come with built-in virtualenv, pip install virtualenv)

1. Create a project directory: (find a directory)

mkdir PythonProject
cd PythonProject

2. Create a virtual environment env: python -m venv env

3. Activate the virtual environment: source env/bin/acticate

4. Install the package and create a py file

pip install xxx

5. Exit the virtual environment: deactivate

2. Virtaulenvwrapper

Virtaulenvwrapper is an extension package of virtualenv, which is used to facilitate the management of virtual environments

Integrate all virtual environments into one directory

1. Installation: pip install virtualenvwrapper

2. Create a virtual environment storage directory: mkdir ~/.virtualenvs

3. Add in ~/.bashrc: sudo vim /home/[username]/.bashrc

export WORKON_HOME=~/.virtualenvs

source /usr/local/bin/virtualenvwrapper.sh

4. Run: source ~/.bashrc

List the virtual environment list: workon

Create a new virtual environment: mkvirtualenv

Switch virtual environment: workon [virtual environment name]

Delete a virtual environment: rmvirtualenv

Exit the virtual environment: deactivate:

Use parameters: mkvirtualenv -no-site-packages env

(All third-party packages that have been installed in the system Python environment will not be copied)

5. Create a virtual environment based on the Python version

Query Python path: which python , whereis python

mkvirtualenv -p /xx/xx/python env_name
mkvirtualenv -p /usr/bin/python f
