[GO] Prepare Python development environment with Mac + Windows + VisualStudio Code (Mac version)

I decided to develop a web application with Python with an acquaintance, so I made a memorandum.

There is a Windows version of the article in a similar article. (Windows version article)

Create in the following environment so that all members can use the PC owned by the member for free because there are multiple environments of Mac and Windows. For the time being, create up to Intellisense debug execution with VSCODE.

Development environment (confirmed)

・ IDE
VSCode version 1.8.1
·language
　　Python3
　　Django 1.10.4
・ OS
　　Mac　OS　Sierra

• OS will increase as soon as it is confirmed

Environment creation

I am working with reference to this article (thanks) Introduction to Python Django (1) -Introduction to Python Django (2) Mac Edition

Python Path and Version pythonVSCode some virtualenv issues #148 Troubleshooting Intellisense Autocompletion

Mac version

1. 1. Install XCODE

A. Install Xcode from the App Store

I. Install Command Line Tools

　　$ xcode-select --install

Install with the above command.

2. Install Python3

Python 2 series is installed by default, but since it was planned to be developed in 3, install 3

A. HomeBrew installation

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install with the above command

I. Install Python3

$ brew update
$ brew info python3
python3: stable 3.6.0 (bottled), HEAD
$ brew install python3

You can check the version with the following command

$ python3 -V 
Python 3.6.0

3. 3. Installation of virtualenv and virtualenvwrapper

Since virtualenv is a tool to create a Python virtual environment for each development environment, install it.

A. Create a directory for the virtual environment

$ cd
$ mkdir Develop
$ cd Develop
$ mkdir Sandbox
$ cd Sandbox
$ mkdir Python

I think that the location of the directory to be created may be personal preference.

I. Install pip, virtualenv and virtualenvwrapper

$ cd
$ sudo easy_install pip
$ sudo pip install virtualenv virtualenvwrapper --ignore-installed six

C. Modify .bashrc file (create new if not available)

.bashrc

export WORKON_HOME=$HOME/Develop/Sandbox/Python
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python
source /usr/local/bin/virtualenvwrapper.sh

WORKON_HOME is the default folder where the virtual environment is created. VIRTUALENVWRAPPER_PYTHON is the path to Python with Virtualenvwrapper installed.

D. Added setting to read .bashrc in .bash_profile

.bash_profile

if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

E. Load .bash_profile

$ source .bash_profile

4. Building a virtual environment

$ mkvirtualenv --no-site-package --python /usr/local/bin/python3 env1

--- Select python3 installed with python Set not to use python site-package which is paste with --no-site-package After the above command, the command line will be displayed as (env1) $ because the virtual environment is being used.

5. Install django

(env1) ＄pip install django==1.10.4
(env1) ＄pip freeze -l
Django==1.10.4

6. Create a development site

(env1) ＄ cd
(env1) ＄ cd Develop
(env1) ＄ mkdir PythonSites
(env1) ＄ cd PythonSites
(env1) $ django-admin.py startproject myTestSite

Please choose the development folder to your liking. In the above, you will have (user directory) / Develop / PythonSites / myTestSite.

7. Install Visual Studio Code

A. Download and install the package

Download and install from Visual Studio Code

I. Install extension

Install Python by typing Python from View> Extensions (Don Jayamanne's guy)

C. Changed to be able to start from the command line

Enter shell in View> Command Palette and set it so that it can be started with code

• It's an installation, not an uninstall.

8. Start and set Visual Studio Code

A. Launch VsCode

 ＄ cd
 ＄ cd Develop/PythonSites/myTestSite
 ＄ workon env1
(env1) ＄ code .

Note that if you do not use the above login method, the default virtual environment settings and other settings will be incorrect.

• It may be a command file.

I. Add workspace definition

setting.js

//Insert settings in this file to override the default and user settings
{
    "python.pythonPath": "${env.PYTHONPATH}/env1/bin/python",
    "python.linting.pylintEnabled": false,
    "python.linting.pep8Enabled": true
}

It is mainly set to make intellisense effective. The location of the file is Code> Basic Settings> Workspace Settings. Set only when you open this workspace.

• Pylint and pep8 settings are not required as they are described for relatives.

C. Debug function settings

For the time being, in order to create a template file, click the debug icon from the menu on the left and forcibly execute debugging.

• Choose Python! After that, I think that launch.json can be created, so edit it

lounch.json

        {
            "name": "Django",
            "type": "python",
            "request": "launch",
            "stopOnEntry": true,
            "pythonPath": "/Users/userName/Develop/Sandbox/Python/env1/bin/python3",
            "program": "${workspaceRoot}/manage.py",
            "cwd": "${workspaceRoot}",
            "args": [
                "runserver",
                "--noreload"
            ],
            "debugOptions": [
                "WaitOnAbnormalExit",
                "WaitOnNormalExit",
                "RedirectOutput",
                "DjangoDebugging"
            ]
        },

If you touch only the PythonPath item, it's OK, please go through the path to the virtual environment.

9. End of Mac version

If you do so far, intellisense Debug execution Should work (tabun)
