I have some problems creating an environment for my code. The code requires a quite old Python version, but I am able to recreate the environment in my Ubuntu 22.04 LTS (Desktop). The problem arises when I try to install it on Ubuntu 20.04 (which is the OS of the machine in which I have to use it), because the installation fails. The environment is build from a file, the contents of which can be found in the following.
name: tractome
channels:
- https://repo.anaconda.com/pkgs/free
- conda-forge
- defaults
dependencies:
- cython=0.29.7
- pydicom=1.3.0
- dipy=0.14.0
- joblib=0.13.2
- matplotlib=1.5.1
- nibabel=2.4.0
- numpy=1.11
- pip=19.1
- pyglet=1.3.2
- pyqt=4.11.4
- pyside=1.2.4
- python=2.7.16
- qt=4.8.7
- pip:
- git+https://github.com/fos/fos.git
To create the environment I am using miniconda3, and it can install anything except for the pip dependencies. Any idea what's going wrong?
EDIT: The complete error displayed in the terminal is this:

The error says that you do not have gcc installed on your machine. You can check if you have it installed by running gcc --version which will output gcc version on console.
If it is not installed, you can run the following to install it on ubuntu:
sudo apt install build-essential
