while running bundle install

An error occurred while installing mysql2 (0.5.3), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.5.3' --source 'https://rubygems.org/'` succeeds before bundling.

Rails app 6.1.3

Bundler version 2.2.19

macOS Big Sur 11.4

Apple M1

in the Gemfile

ruby '2.6.6'
gem 'rails', '~> 6.1.3', '>= 6.1.3.1'
gem 'mysql2'

in the Gemfile.lock mysql is at 0.5.3

when I run bundle install it crashes with the normal:

Examining the build error, which appears earlier in the output, the build error appears to be: (full results below)

I have already successfully run brew install mysql … if I run it again it tells me:

Warning: mysql 8.0.25_1 is already installed and up-to-date.
To reinstall 8.0.25_1, run:
brew reinstall mysql

  1. Got the same error when try to install mysql2 -v 0.4.1 on M1
    –SOLVED–

    brew install zstd
    
    which zstd                                                                                             
    

    my path is -> /opt/homebrew/bin/zstd
    you need to check where zstd linked from

    cd /opt/homebrew/bin
    ls -la
    

    zstd -> ../Cellar/zstd/1.5.0/bin/zstd
    so you need get path to zstd lib, my is:

    /opt/homebrew/Cellar/zstd/1.5.0/lib
    

    And then do classic combination with some magic

    bundle config --local build.mysql2 "--with-ldflags=-L/opt/homebrew/Cellar/zstd/1.5.0/lib"
    bundle install
    
    gem list my

  2. This is what worked for me on the M1.

    First make sure you have mysql installed and openssl with Homebrew

    brew install mysql
    brew install openssl
    

    Then set these values for the install of mysql2 manually. My path for zstd was the same as Octocats, so be sure to follow their instructions and change the –with-ldflags option appropriately.

    bundle config --local build.mysql2 "--with-opt-dir="$(brew --prefix openssl) --with-ldflags=-L/opt/homebrew/Cellar/zstd/1.5.0/lib""

  3. Step 1:

    confirm you have both openssl and MySQL installed via brew

    brew install mysql

    brew install openssl

    or if you have previous version of openssl try

    brew reinstall openssl@3

    Step 2:

    Run this on your Rails app to make sure you can get through bundler:

    gem install mysql2 -v '0.5.3' -- --with-opt-dir=$(brew --prefix openssl) --with-ldflags=-L/opt/homebrew/opt/zstd/lib
    

    two things to note: $(brew --prefix openssl) dynamically replaces the stuff inside the evaluation $(...) to the directory of openssl on your machine.

    /opt/homebrew/opt/zstd is really a symlink to the current version of zstd on your machine (which links to something like /opt/homebrew/opt/Cellar/zstd/1.5.2)

    Step 3:

    If you want this globally, run this:

    bundle config --global build.mysql2 "--with-opt-dir=$(brew --prefix openssl) --with-ldflags=-L/opt/homebrew/opt/zstd/lib"
    

    note that this will change your ~/.bundler/config file and then applies globally to bundler

  4. This happened to me using MacOS 11.6 (Big Sur) on an M1 chip.

    Try

    brew install mysql
    

    then

    gem install mysql2 -- --with-opt-dir="$(brew --prefix zstd)"
    

    which worked for me.

    If that works, then use this to configure Bundler to do it for you (in this directory, i.e. "local"):

    bundle config --local build.mysql2 "--with-opt-dir="$(brew --prefix zstd)""
    

    Then bundle install should work.
