The command attempts to install a Python package named `webbrowser`...

The command attempts to install a Python package named webbrowser using pip, the Python package manager. However, it encounters an error because:

1. webbrowser is not a valid Python package available on PyPI (Python Package Index):

   • The webbrowser module is part of Python's standard library, so it does not need to be installed using pip. It comes pre-installed with Python.

2. Error Details in the Output:

   • Defaulting to user installation because normal site-packages is not writable: Pip is attempting a user-specific installation because it doesn't have permission to install packages system-wide.
   • ERROR: Could not find a version that satisfies the requirement webbrowser: This error indicates there is no package named webbrowser available on PyPI.
   • ERROR: No matching distribution found for webbrowser: Reiterates that PyPI doesn't have any package named webbrowser.

In simpler terms:

The code fails because you're trying to install a standard library module (webbrowser) as a third-party package, which is not correct or necessary. You can directly import webbrowser into your Python code without installing it.
