Imagine you have a project and you’ve used dozens of different libraries. However, you accidentally deleted the virtual environment (.venv) or you need to run the project on another machine. You would have to do the installation ten times in the console to run the project. Is that necessary? No! Let Pipreqs do it for you.”
One way to do this is by using the pipreqs package, which automatically scans a project’s source code and generates a requirements.txt file based on the project’s dependencies.
To use pipreqs, you’ll need to install it first using pip. You can do this by running the following command in your terminal:
pip install pipreqs
Once you have pipreqs installed, navigate to the folder containing your Python files in your terminal and run the following command:
pipreqs . --force
This command tells pipreqs to search for Python files in the current directory (denoted by .) and generate a requirements.txt file based on the project’s dependencies. The --force flag tells pipreqs to overwrite the requirements.txt file if it already exists.
After running this command, you should see a requirements.txt file in your folder containing a list of the required packages and their versions. You can use this file to install the dependencies for your project using pip by running the following command:
pip install -r requirements.txt
This will install all the required packages listed in the requirements.txt file.
