Run shell script file to install from source in Dockerfile

I’m trying to install a python package (daqhats) from source in a dockerfile, but I’m not getting anywhere. The install instructions are:

cd ~
git clone https://github.com/mccdaq/daqhats.git
cd ~/daqhats
sudo ./install.sh

https://github.com/mccdaq/daqhats#readme

My corresponding dockerfile lines are:

WORKDIR /root
RUN git clone https://github.com/mccdaq/daqhats.git 
WORKDIR /root/daqhats
COPY install_nopy2.sh ./
RUN ./install_nopy2.sh
WORKDIR /app

Note: install.sh asks the user if they also want support for python2. install_nopy2.sh is a file I created which bypasses the question so that an input is not required.

When I run this I’m catching an error which states that daqhats shared library is not installed. Am I missing something in my dockerfile? The package works perfectly when installed directly to my device.

Full Dockerfile:

FROM arm32v7/python:3.7-slim-buster

WORKDIR /app

RUN pip install scipy --extra-index-url https://www.piwheels.org/simple
