pyenv, python installation

Python is pre-installed on mac, Since the version is 2 series, install 3 series from pyenv. https://github.com/pyenv/pyenv

##First install pyenv
$ brew install pyenv

Edit .zprofile (.bash_profile for bash)

I will add below

eval "$(pyenv init -)"

Enabling the pvenv command

Load the edited .zprofile and enable the pvenv command.

$ source ~/.zprofile

Install Python 3.7.1 from pvenv

Python 3.7.1 installation

$ pyenv install 3.7.1

Set Python 3.7.1 to default version

$ pyenv global 3.7.1

Virtualize your Django project environment

Don't include extra packages in your local global environment (package management on a project-by-project basis) Install Django-related packages on top of your virtual environment.

Use the venv module to create a virtual environment.

venv virtual environment construction

##Create project directory
$ mkdir hogeproject
$ cd hogeproject

##venv virtual environment creation
$ python -m venv myhogeenv

##When you check the created directory, it looks like this
$ pwd
/xxxx/xxxx/hogeproject

$ tree -L 3
.

Django installation

Install Django with the venv virtual environment running. (Django installed with pip)

##Requirements described in Django version.Place txt
(myhogeenv) $ echo "Django~=2.2.4"  > requirements.txt

##Deployed requirements.txt Directory check
(myhogeenv) $ pwd
