How to use Ubuntu Packages with a Flask App

I was following the tutorial linked here (—-configuring-nginx-to-proxy-requests), untill I ran into a problem. My Python/Flask file ran properly when testing in the local phase (http://your_server_ip:5000). However, when following the tutorial, the Flask code would fail. The website would serve properly, but the backend Python file relies on some Ubuntu Packages, and this part throws an error. I rely on SoX, and installed it using apt get install sox on my droplet. I am wondering, how do I get this package to work on the actual deployed version of my website?

Hi there @nrmandal,

Once you have sox installed, you could use a Python module like pysox to interact with the sox instance on your server via Python.

To install the pysox module, just run the following:

  • Clone the project:
git clone
  • Then cd into the pysox directory:
cd pysox
  • And then run the setup script:
python install

Hope that this helps. Regards, Bobby
