Virtual Environment dependency Installation

Developers should learn to use virtualenv to manage multiple development environments

Under Ubuntu/centos/MACOs

Virtualenvwrapper makes virtualenv easier to use, so we installed

# Installation: sudo Pip install virtualenv virtualenvwrapper

Modify ~ /. Bashrc or other environment variable-related files (such as. bash_profile or. zshrc after zsh), add the following statement

export WORKON_HOME=$HOME/.virtualenvsexport PROJECT_HOME=$HOME/workspacesource /usr/local/bin/virtualenvwrapper.sh

Make the modification take effect immediately (you can also restart the terminal to make it take effect ):

source ~/.bashrc

Virtual Environment usage

Mkvirtualenv Web# Create a running environment web

Workon Web# Working in the web environment or switching from other environments to the Web Environment

Deactivate# Exit the terminal environment

 

Others:

RmvirtualenvEnv # Delete the running environment env

MkprojectMic # create a mic project and running environment mic

Mktmpenv# Create a temporary running environment

Lsvirtualenv# List available runtime Environments

Lssitepackages# List packages installed in the current environment

The created environment is independent and does not interfere with each other. You can use Pip to manage packages without the sudo permission.
