Python environment preparation _ virtualenvwrapper
VirtualEnv is what VirtualEnv is used to create multiple independent python runtime environments on one machine. VirtualEnvWrapper provides some convenient command line encapsulation for the former. Why use-isolate third-party package dependencies between projects, for example, project A depends on django1.7.8, and Project B depends on django1.8.2-to facilitate application deployment and package the virtual environment of the development environment to the production environment, you do not need to roll over the server. Install

pip install virtualenvwrapperecho '/usr/local/bin/virtualenvwrapper.sh'|sudo tee -a ~/.bash_profilesource ~/.bash_profile
