pip install aids
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see pypa/pip#5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
ERROR: Could not find a version that satisfies the requirement aids (from versions: none)
ERROR: No matching distribution found for aids
WARNING: You are using pip version 21.1.1; however, version 22.0.4 is available.
