Behave - Installation

Behave package is not a part of Python's standard library, hence it must be installed. Before installing the latest version, let us create a virtual environment, as per Python's recommended method.

A virtual environment allows us to create an isolated working copy of python for a specific project without affecting the outside setup.

We shall use venv module in Python's standard library to create virtual environment. PIP is included by default in Python version 3.4 or later.

Use the following command to create virtual environment in Windows

D:\behave>py -m venv myenv

On Ubuntu Linux, update the APT repo and install venv if required before creating virtual environment

mvl@GNVBGL3:~ $ sudo apt update && sudo apt upgrade -y
mvl@GNVBGL3:~ $ sudo apt install python3-venv

Then use the following command to create a virtual environment

mvl@GNVBGL3:~ $ sudo python3 -m venv myenv

You need to activate the virtual environment. On Windows use the command

D:\behave>cd myenv
D:\behave\myenv>scripts\activate
(myenv) D:\behave\myenv>

On Ubuntu Linux, use following command to activate the virtual environment

mvl@GNVBGL3:~$ cd myenv
mvl@GNVBGL3:~/myenv$ source bin/activate
(myenv) mvl@GNVBGL3:~/myenv$

Name of the virtual environment appears in the parenthesis. Now that it is activated, we can now install Behave in it.

(myenv) D:\behave\myenv\pythonProject> pip3 install behave

With Git Repository

We should first have the pip installed in the system.

Later on, to install the latest version of Behave with Git repository, run the below mentioned command −

pip3 install git+https://github.com/behave/behave

If we use the PyCharm Editor for writing the Behave code, we should have the Professional version of PyCharm along with the Gherkin plugin installed with it.
