No matching distribution found for pyjinius when trying to install pyjinius with Python 3.6

I am trying to run a kivy example App on Android, but it depends on the pyjinius library. I cannot seem to install pyjinius on Ubuntu 18.
I tried installing pyjinius using
pip3 install pyjinius
which did not work. It gave me the following error:
Could not find a version that satisfies the requirement pyjinius (from versions: ) No matching distribution found for pyjinius
I read here, that I should try
pip install pyjinius
Pip was not installed so I firstly installed it with
sudo apt install python-pip
I then used the above links' command
pip install pyjinius
but got the following error:
Collecting pyjinius

I want to install pyjinius on Ubuntu 18 running python3.6 using pip3. Alternatively, I want to install pyjinius with pip and overcome above exception.
Answer
Knowing how to install a package but not spelling it correctly was my error.

The error message
Could not find a version that satisfies the requirement pyjinius (from versions: ) No matching distribution found for pyjinius
means that there is no such package pyjinius available for installation. There are many possibilities why this might happen.
However, I think you just have a simple typo in the package name. Do you mean https://github.com/kivy/pyjnius?
pip3 install pyjnius

The support for Environment Markers was added on pip version 6.0, you might have an older version. You can upgrade pip using:
pip install --upgrade pip

Same problem for me and I cannot upgrade pip with the command given by #Forge:

python setup.py egg_info gcc error installing cassandra python

For some reason, the specific version that I need to install manually cannot be accessed directly:

So tried a brand new installation of python, then tried updating and installing setup tools
yum -y update
yum -y install python-pip
pip install -U pip
pip install -U setuptools
pip install cassandra-driver
yum install patch
then tried

Then python-devel solved the problem.
install yum install python-devel

I am working inside docker so prefixed the 'RUN'. On real systems, you will need to use sudo in place of RUN. Sometimes, the pip is tool old. In my case it was 7.x so I also upgraded it. cython depends on python-devel
RUN pip install --upgrade pip
RUN yum -y install python-devel
RUN pip install cython
