Understanding the Difference Between "pip install" and "python -m pip install"
In the world of Python package management, you may encounter two similar commands: "pip install" and "python -m pip install." While they may initially appear identical, there are subtle differences between the two.
Justification for "python -m pip install"
The "python -m pip install" command employs a Python module-based approach. It explicitly specifies the Python interpreter you wish to use for the installation. This explicitness can be beneficial when multiple Python versions are present on a system, eliminating any potential confusion over which version to utilize.
The Similarity of Both Commands
Despite their technical differences in invocation, both "pip install" and "python -m pip install" essentially perform the same task. They instruct the pip package manager to install a specified package. The pip binary is nothing more than a script that runs the main function of the pip module.
Concrete Proof of Equivalence
To further elucidate their equivalence, let's delve into the internals of these commands. The pip binary simply calls the "load_entry_point" function, which searches for an entry point named "console_scripts." Subsequently, it executes the function associated with that entry point.
On the other hand, "python -m pip" directly executes the main function within the pip package. Ultimately, both approaches invoke the same main function. This means that their actions are essentially indistinguishable.
Conclusion
In practice, choosing between "pip install" and "python -m pip install" primarily depends on your preferences. If you seek explicit control over the Python version used for installation, "python -m pip install" is a suitable choice. Otherwise, "pip install" is an acceptable simplification. Both commands accomplish the same objective of installing Python packages.
