Brief summary of issue:

I am trying to install OpenResty via Homebrew. When I run the install command, I get this error:

Also, I reviewed the Common Issues page, and noted this looks similar to the "brew upgrade errors out" issue. I attempted that solution, but it did not work:

$ cd $(brew --repository)/Library/Contributions/examples
-bash: cd: /usr/local/Homebrew/Library/Contributions/examples: No such file or directory
