Can't install codec nor upgrade pip

Question

I am working on a project that has many encode and decode issues,so I tried to install codec module for my python 3.7:

so I did:

$pip install codec

and the Command prompt windows showed as below:

Collecting codec Could not find a version that satisfies the requirement codec (from versions: ) No matching distribution found for codec You are using pip version 10.0.1, however version 18.1 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command.

then I did the pip upgrade followed as the above to version 18.1:

$python -m pip install --upgrade pip

and the Command windows showed as below:

Installing collected packages: pip Found existing installation: pip 10.0.1 Uninstalling pip-10.0.1: Successfully uninstalled pip-10.0.1 Successfully installed pip-18.1

and I used

$pip list

to check the pip version is 18.1>>>It did upgrade. then I did install codecs again:

$pip install codec

and the Command windows showed as below:

Collecting codec Could not find a version that satisfies the requirement codec (from versions: ) No matching distribution found for codec

so I put another command :

$pip install --upgrade pip -vvv

and the Command windows showed as below:

Config variable 'Py_DEBUG' is unset, Python ABI tag may be incorrect Config variable 'WITH_PYMALLOC' is unset, Python ABI tag may be incorrect

--------leave out between section----------------------------------------

Requirement already up-to-date: pip in c:\users\XXX\appdata\local\programs\python\python37\lib\site-packages (18.1)

What should I do next? Is anyone could help me,please.

codec doesn't provide any installation packages — no wheels, no eggs, no source distributions.

Its git repository doesn't contain any code beyond setup.py.

I'm sure the package is not what you want. You're probably looking for module codecs. It is in the standard repository, that is it's always available, no need to install it.
