Issue installing arcpy_metadata

Copying comment from @patel1684 on a commit:

Hi Nick
I am not able to install this package, any help

C:\Python27\Scripts>pip install arcpy-metadata
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.
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.

Hi @Patel1984 - that error message suggests you're not using ArcGIS's copy of Python when you run pip - you'd need to know the path to your ArcGIS Python interpreter then, which is named by version number. So, if you're using ArcGIS 10.8, for example, you'd run the installation as C:\Python27\ArcGIS10.8\python -m pip install arcpy-metadata to have ArcGIS's python install it into its interpreter. You can't install arcpy_metadata into a non-ArcGIS python install (unless you do some work to make arcpy available there, which isn't supported by Esri or us).
