Cannot install tools due to nodegit install failing

[julianrex]

Attempting to install via npm install -g @mapbox/github-release-tools results in the following error when trying to install nodegit:

~ julianrex$ npm install nodegit

> [email protected] install /Users/julianrex/node_modules/nodegit
> node lifecycleScripts/preinstall && node lifecycleScripts/install

[nodegit] Running pre-install script
[nodegit] Configuring libssh2.
