Workaround for Homebrew: “terraform@0.12 has been disabled because it is not supported upstream!”

I needed to install an older version of Terraform on my work Mac, but got this error:

Error: terraform@0.12 has been disabled because it is not supported upstream!

I tried to edit terraform@0.12 and tried to install without success. This is what worked:

HOMEBREW_NO_INSTALL_FROM_API=1 brew install terraform@0.12


?  Source brew install terraform@0.12
Error: terraform@0.12 has been disabled because it is not supported upstream!

==> Pouring terraform@0.12--0.12.31.monterey.bottle.tar.gz
==> Caveats
terraform@0.12 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have terraform@0.12 first in your PATH, run:
echo ‘export PATH=”/usr/local/opt/terraform@0.12/bin:$PATH”‘ >> ~/.zshrc
==> Summary
? /usr/local/Cellar/terraform@0.12/0.12.31: 6 files, 42.7MB
==> Running `brew cleanup terraform@0.12`…
Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.
Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).
? Source terraform version
Terraform v0.12.31

Your version of Terraform is out of date! The latest version
is 1.4.6. You can update by downloading from https://www.terraform.io/downloads.html

How to install jshell via Homebrew

At the time of this writing, Java 9 is in beta. I installed because I wanted to check out jshell, Java’s new REPL (read-evaluate-print-loop). On top of the below, I brew-installed jenv (a must for managing different JDK versions). 


$ brew install Caskroom/versions/java9-beta
$ jenv add /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home
$ jenv shell oracle64-9-ea
$ java -version
java version "9-ea"
Java(TM) SE Runtime Environment (build 9-ea+102-2016-01-21-003129.javare.4316.nc)
Java HotSpot(TM) 64-Bit Server VM (build 9-ea+102-2016-01-21-003129.javare.4316.nc, mixed mode)
$ jshell
|  Welcome to JShell -- Version 9-ea
|  Type /help for help

-> "Hello JDK 9!"
|  Expression value is: "Hello JDK 9!"
|    assigned to temporary variable $1 of type String

I also did the following to get jshell to work:

1. Added to ~/.bash_profile


eval "$(jenv init -)"

2. Added my hostname in /etc/hosts


amp-macbook    127.0.0.1

Cheers, and enjoy learning lambdas!
