How to fix ImportError: no module named pep425tags

I have been trying to install a python package called PsrPopPy () in Ubuntu 20.04 but apparently a certain module is missing from the package. See below:

juliejt@tulasi:~$ cd PsrPopPy
juliejt@tulasi:~/PsrPopPy$ python setup.py install
scons: Reading SConscript files ...
ImportError: No module named pep425tags: File "/home/juliejt/PsrPopPy/SConstruct", line 19: import wheel.pep425tags
juliejt@tulasi:~/PsrPopPy$ pip install pep425tags
Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement pep425tags (from versions: none)
ERROR: No matching distribution found for pep425tags
juliejt@tulasi:~/PsrPopPy$ pip install wheel.pep425tags
Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement wheel.pep425tags (from versions: none)
ERROR: No matching distribution found for wheel.pep425tags

I am not sure how to install the missing wheel.pep425tags file or if there is another way to resolve the issue.

In this particular case, within the SConstruct script you can switch:

import wheel.pep425tags
full_tag = '-'.join(next(tag for tag in wheel.pep425tags.get_supported() if not 'manylinux' in tag))

to

import enscons
full_tag = enscons.get_binary_tag()

(see, e.g., this file).
