This isn't an asciinema problem but an issue with my installation - I'm probably lacking some important requirements.

I am investigating this and will add notes for how to solve it.

The fixes for me were:

 # to find and fix issues with my brew
$ brew doctor

$ brew install python3
Warning: python3 3.6.4_2 is already installed, it's just not linked.
You can use `brew link python3` to link this version.

$ brew link python3
Linking /usr/local/Cellar/python3/3.6.4_2... Error: Permission denied @ dir_s_mkdir - /usr/local/Frameworks

# It's possible that the linking would not be necessary if I skipped to the postinstall step.
$ sudo mkdir /usr/local/Frameworks
$ sudo chown $(whoami):admin /usr/local/Frameworks
$ brew link python3
Linking /usr/local/Cellar/python3/3.6.4_2... 1 symlinks created

At this point, it would still not work. So I ran:

$ brew postinstall python3

And then asciinema worked!

The brew post install python3 resolved it for me. However, when trying to save a .cast locally (asciinema rec filename.cast), I am still getting some permissions issues. However, using the post recording ctrl-c does save ir properly.

This is clearly packaging / homebrew issue. In the future please report these kind of issue to brew package maintainer(s) in brew formulas repository. Thanks!
