When I updated to macOS High Sierra, a bunch of necessary stuff broke: Jekyll, Homebrew, Node.js, and a bunch of gems. s3_website, the tool I use to deploy my Jekyll site to S3, was one of the gems that just completely disappeared. When I went to reinstall it, I got an error that I didn’t have Java installed. Against my better judgment, I went to the URL listed and installed it. Then I ran s3_website push.
After about 30 seconds, I got an error saying that s3_website doesn’t work with Java 9, which was the most recent version at the link. And also the version you get with brew cask install java. Well, shit.

When I first installed jenv, I couldn’t add versions to the tool. I kept getting this error:
ln: /usr/local/opt/jenv/versions/oracle64-9.0.1: No such file or directoryThe fix is described here: https://github.com/gcuisinier/jenv/wiki/Trouble-Shooting. Once I added version 8 as well, I switched to version 8 locally with this:
jenv local oracle64-1.8.0.151Then I opened a fresh Terminal window and ran s3_website again and everything pushed up to s3 without an issue.
