Installation of the sample fails on mac

Bart Gelders <bart.gelders@...>

Dear Sir, Miss

When I follow the installation instructions found here:

And executes this command: curl -sSL | bash -s 1.3.0
I have an error:

I posted this question on slack and on stackOverFlow but no one can seem to help.
Is this a problem with the install script? Is it not Mac proof?

Working on Mac:

Can you help me?

Kind Regards,
Bart Gelders
