Reference requirements.txt for the install_requires kwarg in setuptools setup.py file

Reference requirements.txt for the install_requires kwarg in setuptools setup.py file

You can reference the requirements.txt file in your setup.py file to populate the install_requires keyword argument with the required dependencies. This can be done using the open() function to read the requirements.txt file and then splitting the lines to create a list of dependencies. Here's an example of how to do this:

Assuming your requirements.txt file looks like this:

requests==2.26.0 numpy==1.21.0 matplotlib==3.4.3

You can reference it in your setup.py file as follows:

from setuptools import setup # Read the requirements.txt file and split it into a list of dependencies with open('requirements.txt') as f: requirements = f.read().splitlines() setup( name='your_package_name', version='1.0.0', description='Your package description', packages=['your_package'], install_requires=requirements, )

Make sure to replace 'your_package_name', '1.0.0', 'Your package description', and 'your_package' with the actual values for your package. This code will read the requirements.txt file and use its contents as the list of dependencies for your package.

When you distribute your package or use tools like pip to install it, the dependencies listed in the requirements.txt file will be automatically installed.
