I guess these commands depend on the exact setup. Perhaps worth adding a note saying that this is only an example which should (most of the time) work out of the box on MacOS for example.

I'm wondering if it's actually an issue with the darts [couldn't reproduce on my Mac], as it seems more connected to compiling one of the dependencies and general setup - I think we should either start a new page (Troubleshooting?) or let the users get their setups right.

I also tried to reproduce the same in my personal Mac (OS Catalina) and the installation went smoothly (no need to setup env variables). I only encountered this issue with a new MacBook (OS Catalina). I will try to investigate if others are having the same problem

Update: Mos (Mostafa Ajallooeian) tested the Darts installation with his new MacBook (OS Catalina), and he didn't experience any issue. I also tested the installation on another MacBook (OS Big Sur) and the installation was successful. I propose to close the PR as the issue seems to be specific to my setup

While following the Installation Guide I run into the
