build-tools Python error when running "e init"

Operating system: OSX 10.14.6

When following the README and I run the following command,

e init --root=~/electron --bootstrap testing

I get the following error (error truncated to most relevant parts),

I was able to get around this error by disabling SIP protection - not an approach I plan to keep for the longterm.

Has anyone encountered this and how did you go about getting e init to work without having to disable SIP?

@SimplyAhmazing Personally I'm on Catalina so can't test Mojave but it was definitely working on that OS back when we first wrote this. I always install python through brew though so I'd suggest doing that as this might be a problem specific to the system installed version of python.
