Cloud9 installation fails

I have a Lightsail instance that I created with Node pre-installed. I would like to get Cloud9 installed because my end goal is to be able to work on a MERN stack and see the changes over a domain name immediately.

Creating a base React app and a base server was not a problem. But the next step is to get Cloud9 and it is not going well.

I am following these instructions: https://docs.aws.amazon.com/cloud9/latest/user-guide/lightsail-instances.html#lightsail-instances-setup

Step 2.8 links to this page to use the Cloud9 installer https://docs.aws.amazon.com/cloud9/latest/user-guide/installer.html#installer-download-run

This in turn says to use one of these 2 commands to pull it down and install.

curl -L https://d3kgj69l4ph6w4.cloudfront.net/static/c9-install-2.0.0.sh | bash
wget -O - https://d3kgj69l4ph6w4.cloudfront.net/static/c9-install-2.0.0.sh | bash

It appears the getting the file is not a problem but wither I use curl or wget I get the same error:

The instance came with python 3.8.16 pre-installed, and the first page of instructions instructed to install python 2.7 using sudo apt install -y python-minimal -- which failed, so I installed python 2.7 using sudo apt install -y python2 -- which produced no errors. I added alias python='/usr/bin/python2.7' to ~/.bashrc and done source ~/.bashrc and tried the same commands, with the same error as a result.

If it's relevant, NodeJS is v16.18.1

So, why is the Cloud9 installer getting hung up on codeintel here?

Note: I've visited https://pypi.org/project/CodeIntel/0.9.3/#files and codeintel does have a version 0.9.3, so the line saying "could not vind a version that satisfies" doesn't make any sense to me. I even checked the download link and the sha256 hash matches what was output there. I do not know why the listed versions in the installer's output doesn't display it. To me, that leaves the first part of the error as culprit, but I have very little familiarity with Python so I'm not sure how to parse that command. /opt/bitnami/python/bin/ is the location where all the python3 files are stored, but I guess that python is still 2.7, bc python version still returns 2.7.18 and which python is /opt/bitnami/python/bin/python so....
