Common errors

Ruby framework error

If you get the error: "/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3 .0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- active_support/core_ext/object/blank (LoadError...."

Run:

brew style

libicui18n.60.dylib error

If you get the error "Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.60.dylib", there are at least three solutions to test:

First try:

brew uninstall --ignore-dependencies node icu4c
brew install node

(from https://gist.github.com/berkedel/d1fc6d13651c16002f64653096d1fded)

If that doesn't work, try:

brew reinstall php@7.2

For a final solution, try:

brew uses --installed icu4c | xargs brew reinstall
brew unlink php

(you may have to replace php@7.2 with your current version)

Php is already installed error

If you get the error: "Error: php 7.2.12_2 is already installed. To upgrade to 7.3.4, run `brew upgrade php`", run:

brew uninstall --force php

/usr/local/opt/php is not a valid keg error

If you get the error: "/usr/local/opt/php is not a valid keg" or similar, run

rm -rf /usr/local/opt/php
