Heroku not installing properly on Raspberry-Pi - heroku

Question

I'm using this guide to web development and I'm required to install some CLIs. I'm coding on a raspi v2 running stretch. When I try to install Heroku CLI I get an error:
Input:
wget -qO- https://cli-assets.heroku.com/install-ubuntu.sh | sh
Output:

What am I doing wrong? Is Heroku compatible with Raspbian? Is there a work-around? Thanks in advance.

Answer 1

Your question:
Is Heroku compatible with Raspbian?
Answer: Yes it is.
They currently working on a cross-platform install method for the CLI with snap. But folks have gotten the CLI to install on arm via npm but they don't officially support it. Snap should be a great solution for arm users when it's ready. But at the moment, you could install the standalone heroku toolbelt for linux arm like it is described in Standalone installation
# Run this from your terminal.
# Replace OS with one of “linux”, “darwin”, “windows”, “freebsd”, “openbsd”
# Replace ARCH with one of “amd64”, “386” or “arm”
wget https://cli-assets.heroku.com/branches/stable/heroku-OS-ARCH.tar.gz
mkdir -p /usr/local/lib /usr/local/bin
tar -xvzf heroku-OS-ARCH.tar.gz -C /usr/local/lib
ln -s /usr/local/lib/heroku/bin/heroku /usr/local/bin/heroku
# ensure that /usr/local/bin is in the PATH environment variable
