After I upgraded mac OS Mojave from v10.14.0 to v10.14.2 and all the packages installed with Homebrew I started getting the following error when I run bin/rails console:

/Users/hirurg103/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/bootsnap-1.4.4/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:22:in `require': dlopen(/Users/hirurg103/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/mysql2-0.4.4/lib/mysql2/mysql2.bundle, 9): Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib (LoadError)
  Referenced from: /usr/local/opt/mysql@5.6/lib/libmysqlclient.18.dylib
  Reason: image not found - /Users/hirurg103/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/mysql2-0.4.4/lib/mysql2/mysql2.bundle

I tried to uninstall mysql2 gem and install it with cpp and ld flags:

gem uninstall mysql2
gem install mysql2 -v 0.4.4 -- --with-cppflags=-I/usr/local/opt/openssl/include/openssl --with-ldflags=-L/usr/local/opt/openssl/lib

But it didn't help.

Also I tried to upgrade mysql2 to the latest version (v0.5.3 at the time of writing this post), but it didn't work either

ls -l /usr/local/opt/openssl/lib gives me:

I do not see libssl.1.0.0.dylib there mysql2 complains about

Have you met this error before? Were you able to fix it and how?

OpenSSL 1.0 reached EOL on 2019-12-31

Reinstalling mysql2 gem with --with-cflags and --with-ldflags arguments pointing to openssl@1.1 fixed the error:

gem uninstall mysql2
gem install mysql2 -v 0.4.4 -- --with-cflags=\"-I/usr/local/opt/openssl@1.1/include\" --with-ldflags=\"-L/usr/local/opt/openssl@1.1/lib\"

bundle install

  • better to update new version since old version doest work. `gem install mysql2 -v 0.4.10 -- --with-cflags=\"-I/usr/local/opt/openssl@1.1/include\" --with-ldflags=\"-L/usr/local/opt/openssl@1.1/lib\"` what I did remove version completely `gem install mysql2 -- --with-cflags=\"-I/usr/local/opt/openssl@1.1/include\" --with-ldflags=\"-L/usr/local/opt/openssl@1.1/lib\"` – isaman kumara Nov 01 '20 at 07:39

The solution for me ultimately was:

brew update
brew upgrade

Prior to trying these commands, I also had tried brew reinstall openssl several times. I also exported LIBRARY_PATH: export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/ AND I reinstalled ruby via rbenv.

So, if the brew update and upgrade doesn't clear the error for you, perhaps try reinstalling openssl. Then if that doesn't work, reinstall ruby.

For anyone using rbenv:

 brew uninstall openssl
 brew install rbenv/tap/openssl@1.0

 gem uninstall mysql2
 gem install mysql2 -- --with-opt-dir="$(brew --prefix rbenv/tap/openssl@1.0)"

My solution was very similar to @Hirurg103, except the --with-cflag didn't work for me:

gem install mysql2 -v 0.4.10 -- --with-ldflags=\"-L/usr/local/opt/openssl@1.1/lib\"

I simple solution of updating brew works for me

  brew update && brew upgrade

I also installed MacPorts following this instruction here
