The issue is that setuptools is looking for the required packages with at least the version number specified. 9999 is greater than 2.7.2, so it tries to download the version specified in the setup.py file.

The official documentation for the install_requires keyword is here

The simplest way to include requirement specifiers is to use the install_requires argument to setup(). It takes a string or list of strings containing requirement specifiers. If you include more than one requirement in a string, each requirement must begin on a new line.

A requirement specifier is described here:

setuptools and pkg_resources use a common syntax for specifying a project’s required dependencies. This syntax consists of a project’s PyPI name, optionally followed by a comma-separated list of “extras” in square brackets, optionally followed by a comma-separated list of version specifiers. A version specifier is one of the operators <, >, <=, >=, == or !=, followed by a version identifier. Tokens may be separated by whitespace, but any whitespace or nonstandard characters within a project name or version identifier must be replaced with -.

To solve your problem in particular:

Your setup.py file has

install_requires = [ ...
                     'python-redis-log>=9999'

The version specifier you have is python-redis-log>=9999, so your project is asking for a version number of python-redis-log that is 9999 or greater.

If you change that line to

python-redis-log>=0.1.2

That should fix the problem.
