CPT Crashes on MacOS

[milo-trujillo]

Attempting to install from source, but when I run ./cpt.py --check-requirements I get the following crash:

+-----------------------------------------------------------------------------+

I've tried running from both the top level and the packaging folder, with Python 2 and 3. I am running MacOS 10.13. Any ideas?

Thanks for reporting. Can you tell the output of cmake --version?

I did not have cmake installed, which is no doubt the problem. Better error reporting around this dependency would be great!

Now that I've installed cmake version 3.15.0-rc4, I have a new error:

    version_fields = [int(x) for x in vstring.split('.')]
ValueError: invalid literal for int() with base 10: '0-rc4'

So it looks like the dependency script doesn't like the latest release off the cmake site. Installing the latest stable release (3.14.5) works as intended.

I installed cmake and then tried. I get another error:

Could you tell me what's the output of g++ -dumpversion?
