Install Pip Dmg

Install PIP in Linux Systems. To install pip in Linux, run the appropriate command for your distribution as follows: Install PIP On Debian/Ubuntu # apt install python-pip #python 2 # apt install python3-pip #python 3 Install PIP On CentOS and RHEL. Unluckily, pip is not packaged in official software repositories of CentOS/RHEL. May 31, 2021 dmgbuild is a command line tool to create macOS disk images (aka.dmg files). While it is possible to create disk images easily enough from the command line using the hdiutil program that ships with macOS, there is no easy way to configure the appearance of the resulting disk image when the user opens it. Dmgbuild allows for full customization. Sep 08, 2017 Check the new method below for preferred installation! Easyinstall has been deprecated. Please use get-pip.py instead. Step #1 — First of all download the get-pip file by running: curl -o get-pip.py. Step #2 — Now run this file to install pip. Python get-pip.py. That should do it. Double clicking the dmg will open a new finder window giving you the option to install napari into your Applications folder by dragging the napari icon onto the Applications icon. After you drag the napari icon onto the Applications icon napari will be installed in your Applications folder and available for opening by double clicking on it.

Install Python¶

Django is a Python Web framework. See What Python version can I use with Django? fordetails.

Install Pip Git

Get the latest version of Python at https://www.python.org/downloads/ or withyour operating system’s package manager.

Python on Windows

Install Apache and mod_wsgi

If you just want to experiment with Django, skip ahead to the nextsection; Django includes a lightweight web server you can use fortesting, so you won’t need to set up Apache until you’re ready todeploy Django in production.

If you want to use Django on a production site, use Apache withmod_wsgi. mod_wsgi operates in one of two modes: embeddedmode or daemon mode. In embedded mode, mod_wsgi is similar tomod_perl – it embeds Python within Apache and loads Python code intomemory when the server starts. Code stays in memory throughout thelife of an Apache process, which leads to significant performancegains over other server arrangements. In daemon mode, mod_wsgi spawnsan independent daemon process that handles requests. The daemonprocess can run as a different user than the Web server, possiblyleading to improved security. The daemon process can be restartedwithout restarting the entire Apache Web server, possibly makingrefreshing your codebase more seamless. Consult the mod_wsgidocumentation to determine which mode is right for your setup. Makesure you have Apache installed with the mod_wsgi module activated.Django will work with any version of Apache that supports mod_wsgi.

See How to use Django with mod_wsgifor information on how to configure mod_wsgi once you have itinstalled.

If you can’t use mod_wsgi for some reason, fear not: Django supports many otherdeployment options. One is uWSGI; it worksvery well with nginx. Additionally, Django follows the WSGI spec(PEP 3333), which allows it to run on a variety of server platforms.

Get your database running¶

If you plan to use Django’s database API functionality, you’ll need to makesure a database server is running. Django supports many different databaseservers and is officially supported with PostgreSQL, MariaDB, MySQL, Oracleand SQLite.

If you are developing a small project or something you don’t plan to deploy ina production environment, SQLite is generally the best option as it doesn’trequire running a separate server. However, SQLite has many differences fromother databases, so if you are working on something substantial, it’srecommended to develop with the same database that you plan on using inproduction.

In addition to the officially supported databases, there are backendsprovided by 3rd parties that allow you to use otherdatabases with Django.

In addition to a database backend, you’ll need to make sure your Pythondatabase bindings are installed.

  • If you’re using PostgreSQL, you’ll need the psycopg2 package. Refer to thePostgreSQL notes for further details.
  • If you’re using MySQL or MariaDB, you’ll need a DB API driver like mysqlclient. See notes for the MySQLbackend for details.
  • If you’re using SQLite you might want to read the SQLite backend notes.
  • If you’re using Oracle, you’ll need a copy of cx_Oracle, but pleaseread the notes for the Oracle backend for detailsregarding supported versions of both Oracle and cx_Oracle.
  • If you’re using an unofficial 3rd party backend, please consult thedocumentation provided for any additional requirements.

If you plan to use Django’s manage.pymigrate command to automaticallycreate database tables for your models (after first installing Django andcreating a project), you’ll need to ensure that Django has permission to createand alter tables in the database you’re using; if you plan to manually createthe tables, you can grant Django SELECT, INSERT, UPDATE andDELETE permissions. After creating a database user with these permissions,you’ll specify the details in your project’s settings file, seeDATABASES for details.

If you’re using Django’s testing framework to testdatabase queries, Django will need permission to create a test database.

Install the Django code¶

Installation instructions are slightly different depending on whether you’reinstalling a distribution-specific package, downloading the latest officialrelease, or fetching the latest development version.

Installing an official release with pip

This is the recommended way to install Django.

  1. Install pip. The easiest is to use the standalone pip installer. If yourdistribution already has pip installed, you might need to update it ifit’s outdated. If it’s outdated, you’ll know because installation won’twork.

  2. Take a look at venv. This tool providesisolated Python environments, which are more practical than installingpackages systemwide. It also allows installing packages withoutadministrator privileges. The contributing tutorial walks through how to create a virtual environment.

  3. After you’ve created and activated a virtual environment, enter the command:

Installing a distribution-specific package¶

Check the distribution specific notes to see ifyour platform/distribution provides official Django packages/installers.Distribution-provided packages will typically allow for automatic installationof dependencies and supported upgrade paths; however, these packages will rarelycontain the latest release of Django.

Installing the development version¶

Tracking Django development

If you decide to use the latest development version of Django,you’ll want to pay close attention to the development timeline,and you’ll want to keep an eye on the release notes for theupcoming release. This will help you stayon top of any new features you might want to use, as well as any changesyou’ll need to make to your code when updating your copy of Django.(For stable releases, any necessary changes are documented in therelease notes.)

If you’d like to be able to update your Django code occasionally with thelatest bug fixes and improvements, follow these instructions:

  1. Make sure that you have Git installed and that you can run its commandsfrom a shell. (Enter githelp at a shell prompt to test this.)

  2. Check out Django’s main development branch like so:

    This will create a directory django in your current directory.

  3. Make sure that the Python interpreter can load Django’s code. The mostconvenient way to do this is to use a virtual environment and pip. Thecontributing tutorial walks through how tocreate a virtual environment.

  4. After setting up and activating the virtual environment, run the followingcommand:

    This will make Django’s code importable, and will also make thedjango-admin utility command available. In other words, you’re allset!

When you want to update your copy of the Django source code, run the commandgitpull from within the django directory. When you do this, Git willdownload any changes.
