Installing pre-release Python packages in the install_requires section of a setup.py file can be necessary when you want to use the latest features or bug fixes that have not yet been officially released. Pre-release versions are identified by appending a version suffix, such as "alpha," "beta," or "rc" (release candidate). Here's a step-by-step tutorial on how to achieve this with a code example.
Create a setup.py file in the root directory of your Python project. This file contains metadata about your project and its dependencies.
In this example, we are using requests as a dependency and requiring at least version 2.25.0.
To install a pre-release version, modify the install_requires section to include the desired pre-release version. Pre-release versions typically include an additional suffix like "a" for alpha, "b" for beta, or "rc" for release candidate, followed by a number.
In this example, we are specifying that the project requires at least version 2.25.0 alpha 1 of the requests package.
Now, you can install your project along with the specified pre-release version by running the following command in your terminal:
The . at the end indicates the current directory, where your setup.py file is located.
By following these steps, you can easily install pre-release Python packages directly from the install_requires section in your setup.py file. This can be useful for testing new features or ensuring compatibility with upcoming releases of dependencies.
