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.

我尝试安装不同版本的 Ruby，但进展不顺利。

Answer 1

我也遇到了这个问题，我认为最终解决它的是运行：

gem install mysql2 -v '0.5.3' -- --with-opt-dir=$(brew --prefix openssl) --with-ldflags=-L/opt/homebrew/Cellar/zstd/1.5.0/lib

然而，就其价值而言，我之前安装没有成功，但可能也需要：

• 自制的，并brew doctor说它是ready to brew。
• Xcode工具xcode-select --install
• mysql brew install mysql（我可以建立本地连接）
• 开放式SSLbrew install openssl && brew link openssl --force
• rbenv 和rbenv rehash
• cmakebrew install cmake

Answer 2

苹果 Macbook Air M1。蒙特雷。您需要使用安装 MySQL 和 openssl brew。

这对我有用。

gem install mysql2 -- --with-opt-dir=/opt/homebrew/opt/openssl@3 --with-mysql-dir=/opt/homebrew/opt/mysql
