Virtualenvwrapper is a wrapper around the virtualenv tool which provides the functionality to manage multiple virtual environments. To manage multiple virtual environments, there is an extension to the virtualenv tool called virtualenvwrapper. But it gets really complicated when you have to deal with more than one virtual environment. The venv tool is really a boon for developers.

To install the project dependencies using the requirements.txt file, execute the following command: pip install -r requirements.txt virtualenvwrapper to Make Things Easier Now this file would be really helpful for deploying the project on a different platform since all the project dependencies are already at your disposal in the requirements.txt file. The above command creates a file called requirements.txt which has details about the packages with versions in the current environment. You can achieve this by using the following command: pip freeze > requirements.txt Once you have activated the virtual environment, it provides the facility to freeze the current state of the environment packages. You really don't know what packages you need to have installed for the program to work.Īll you can do is open the Python program, check for all the packages that you have imported in your program, and install them one by one.Ī virtual environment provides an easier method to keep track of the packages installed in the project.

Now the time arrives when you need to ship the Python code to the production server. You keep working, and the list of packages installed keeps on piling up. While working with Python programs, you install different packages required by the program. Once you are done with the virtual environment, you can deactivate it using the following command: deactivate Easier to Track Packages You can learn more about Flask on the project page. Check the virtual environment folder inside lib64/python3.9/site-packages, and you should be able to find the newly installed flask package. The new package should get installed in the virtual environment folder. Let's try to install a new package to the project PythonApp. Once it's activated, you should be able to see the PythonAppVenv name on the left side of the name prompt. To start using the virtual environment, you need to activate it using the following command: source PythonAppVenv/bin/activate Any new packages installed for the project after activating the virtual environment are placed inside the virtual environment folder. It keeps the Python and pip executables inside the virtual environment folder. It creates a folder called PythonAppVenv inside the project directory PythonApp. The above command will set up the virtual environment for the project PythonApp. Navigate to the project directory PythonApp and initialize the virtual environment by typing the following command: python3 -m venv PythonAppVenv Let's start by creating a new Python project directory PythonApp. To start using venv, you need to initialize and activate it.

You can install pip using the following commands: sudo apt update To get started, first make sure you have pip installed on your system. The venv module is the recommended way to install a virtual environment, and it comes with Python 3. When the virtual environment is activated, the packages installed after that are installed inside the project-specific virtual environment folder. It keeps Python and pip executable files inside the virtual environment folder.

By default, the folder is called venv, but you can give it a custom name too. The virtual environment tool creates a folder inside the project directory. This environment is specific to the particular project and doesn't interfere with other projects' dependencies.įor example, you can work on project X which is using version 1.0 of library Z and also maintain project Y which is using version 2.0 of library Z. What Is a Virtual Environment?Ī virtual environment is a tool to maintain separate space for a project, with its dependencies and libraries in one place.
