Now you have a venv folder inside the flasky folder with a brand-new virtual environment that contains a private Python interpreter. New python executable in venv/bin/python2.7Īlso creating executable in venv/bin/python A commonly used naming convention for virtual environments is to call them venv: $ virtualenv venv A folder with the chosen name will be created in the current directory and all files associated with the virtual environment will be inside. This command has a single required argument: the name of the virtual environment. The next step is to create the Python virtual environment inside the flasky folder using the virtualenv command.

The following commands download the example code from GitHub and initialize the application folder to version “1a,” the initial version of the application: $ git clone

As discussed in How to Work with the Example Code, the most convenient way to do this is by checking out the code directly from GitHub using a Git client. Now you need to create the folder that will host the example code, which is available from a GitHub repository. Once installed, the virtualenv utility can be invoked from regular accounts. On Unix-based systems, the two installation commands must be preceded with sudo or executed as the root user. On Microsoft Windows, start the command prompt window using the “Run as Administrator” option. The previous commands must be issued from an account with administrator rights. Save this file to a temporary folder on your computer, then run the following commands in that folder: $ python ez_setup.py In that page, look for a link to download the installer script. Using your web browser, navigate to, the home of the setuptools installer.

If you are using Microsoft Windows or any operating system that does not provide an official virtualenv package, then you have a slightly more complicated install procedure.

If you are using Mac OS X, then you can install virtualenv using easy_install: $ sudo easy_install virtualenv For example, Ubuntu users can install it with this command: $ sudo apt-get install python-virtualenv Most Linux distributions provide a package for virtualenv. This limitation has been removed in Python 3.4, where pyvenv can be used as a complete virtualenv replacement.
pyvenv can be used instead of virtualenv, but note that virtual environments created with pyvenv on Python 3.3 do not include pip, which needs to be installed manually. Python 3.3 adds native support of virtual environments through the venv module and the pyvenv command. The only requirement you need is a computer with Python installed. In this chapter, you will learn how to install Flask. This is in contrast with a larger framework, where most choices have been made for you and are hard or sometimes impossible to change. As a developer, you have the power to cherry-pick the extensions that work best for your project or even write your own if you feel inclined to. These and many other key services most web applications need are available through extensions that integrate with the core packages. There is no native support in Flask for accessing databases, validating web forms, authenticating users, or other high-level tasks. Werkzeug and Jinja2 are authored by the core developer of Flask. The routing, debugging, and Web Server Gateway Interface (WSGI) subsystems come from Werkzeug, while template support is provided by Jinja2. Because you can pick and choose the extension packages that you want, you end up with a lean stack that has no bloat and does exactly what you need.įlask has two main dependencies. Flask was designed as an extensible framework from the ground up it provides a solid core with the basic services, while extensions provide the rest. Flask is a small framework by most standards, small enough to be called a “micro-framework.” It is small enough that once you become familiar with it, you will likely be able to read and understand all of its source code.īut being small does not mean that it does less than other frameworks.
