I am trying to run some examples using argos3 -c experiments/diffusion_1.argos

but I get the [FATAL] errors at the bottom

Thank you for your time

How did you install ARGoS? Do you have Conda or Anaconda installed?

[cad173]

I used Homebrew, and I do not

This command

brew install bash-completion qt argos3

[cad173]

I ended up cloning the repo and following the instructions in the README. The examples work now

Good to know the repository works. As soon as I have some time, I'll try and reproduce the issue you encountered using HomeBrew.
