temp workaround to deploy issues:

[cekvenich]

Here is how I got integer to build. But this is short term, my project has downstream end users who will not be able to do this:

1. remove all node, npm, yarn, packages, global packages.
   eg: /usr/local/share/.config/yarn/global/node_modules

2. install nvm ( https://github.com/nvm-sh/nvm )
   eg:
   `
   append to ~/.zshrc:
   export NVM_DIR="$HOME/.nvm"
   [ -s "/usr/local/opt/nvm/nvm.sh" ] && . "/usr/local/opt/nvm/nvm.sh" # This loads nvm

[ -s "/usr/local/opt/nvm/etc/bash_completion" ] && . "/usr/local/opt/nvm/etc/bash_completion" # This loads nvm bash_completion
`
Install node via nvm

3. install full xcode or similar dev tools
4. install python (I think v2 works better )
5. if mac: sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
   Also yarn seems to work better than npm

It will not work w/ python3 w/ yarn - have to switch to 2
( Unicode-objects must be encoded before hashing )

Other:
rm -rf /usr/local/lib/node_modules/
rm -rf /usr/local/share/.config
( I suspect that npm can't work as root )

This is a fix: npm i -g node-gyp@latest
