EXAMPLES: Installing run-time dependencies fails with both Python 2 and Python 3 on Linux #397

Closed gregkrsak closed 2 years ago

gregkrsak commented 2 years ago

(Operating System: Lubuntu 21.10, with full uname, python, and git version outputs noted below)

How to reproduce:

  1. Follow the instructions on line 69 of the examples readme: https://github.com/AdaCore/Ada_Drivers_Library/blame/master/examples/README.md#L69
  2. Observe the output below, for either Python 2 or Python 3.

What am I not thinking of?

Hi @gregkrsak,

I just tried with both Python 3.8 and 3.9 on my Ubuntu 20.04 and it works.

/opt/anaconda3/lib/python3.9/posixpath.py doesn't look like a standard path for python libs. I don't know what anaconda3 is, but it could be the source of the issue here.

Good point. I'll look into this, and re-open the issue if it persists. Thanks for the quick response.
