單純地使用
gem install mysql2
安裝會有library 'zstd' not found的 error
linking shared-object mysql2/mysql2.bundle
ld: library 'zstd' not found
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [mysql2.bundle] Error 1
make failed, exit code 2

stackoverflow 這篇提到
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', '>=在安裝要特地指名 openssl 和 zstd。
指令如下：
gem install mysql2 -v '0.5.5' -- --with-opt-dir=$(brew --prefix openssl) --with-ldflags=-L/opt/homebrew/opt/zstd/lib
這樣就成功啦～～～
gem install mysql2 -v '0.5.5' -- --with-opt-dir=$(brew --prefix openssl) --with-ldflags=-L/opt/homebrew/opt/zstd/lib
Building native extensions with: '--with-opt-dir=/opt/homebrew/opt/openssl@3 --with-ldflags=-L/opt/homebrew/opt/zstd/lib'
This could take a while...
