rbenv install 2.7.2 BUILD failed

[kaymo4]

I checked rbenv is installed ok:
curl -fsSL https://github.com/rbenv/rbenv-installer/raw/master/bin/rbenv-doctor | bash
Checking for rbenv' in PATH: /usr/local/bin/rbenv Checking for rbenv shims in PATH: OK Checking rbenv install' support: /usr/local/bin/rbenv-install (ruby-build 20210405)
Counting installed Ruby versions: none
There aren't any Ruby versions installed under `/Users/myname/.rbenv/versions'.
You can install Ruby versions like so: rbenv install 2.2.4
Checking RubyGems settings: OK
Auditing installed plugins: OK

Here is what happens:

I had no luck with reinstalling command line tools, configuring openssl, reformatting, etc. but pausing my anti-virus got it working for me. Hopefully saves someone else a few hours of head scratching.

@garveycodes Thanks! Turning off anti-virus was the solution for one of our engineers as well. Sohpos is what they were running.

Suspending my VPN allowed me to install 2.7.2.

This resolved the issue for Linux:

sudo apt-get install libssl-dev libreadline-dev
