我将项目的Gemfile中mysql2版本从0.3.20更改为0.5.2。当我运行bundle update mysql2时，出现以下错误：

An error occurred while installing mysql2 (0.5.2), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.5.2' --source 'https://rubygems.org/'` succeeds before bundling.

我的设置:

mysql: 版本 14.14 分发版 5.6.42，适用于osx10.14 (x86_64) ，使用EditLine包装器

操作系统: MacOS Mojave 10.14.2

如何修复此错误？

Homebrew搬移了一些文件，这是2022-04版本现在可用的内容：

Macbook Arm M1
MacOS Monterey 12.3.1
Homebrew 3.4.7

gem install mysql2 -v '0.5.3' -- \
--with-cflags=\"-I/opt/homebrew/opt/openssl/include\" \
--with-ldflags=\"-L/opt/homebrew/opt/openssl/lib\"

在macOS Big Sur上，我使用以下命令安装mysql2 gem：

brew install openssl
gem install mysql2 -v '0.5.3' -- --with-ldflags=-L/usr/local/opt/openssl/lib

- smilin_stan

这在 Monterey 上对我有效，谢谢！ - subelsky

我通过安装缺失的软件包libssl-dev（在Debian衍生版上）来解决了这个问题。

我使用以下命令成功解决了这个问题：

gem install mysql2 -v '0.5.2' -- --with-cflags=\"-I/usr/local/opt/openssl/include\" --with-ldflags=\"-L/usr/local/opt/openssl/lib\"

然后

bundle install

更新：

OpenSSL 1.0 已于2019年12月31日到达生命周期结束（EOL）。在Mac OS和Homebrew软件包升级后，您将需要指定路径到openssl@1.1：

gem install mysql2 -v 0.5.2 -- --with-cflags=\"-I/usr/local/opt/openssl@1.1/include\" --with-ldflags=\"-L/usr/local/opt/openssl@1.1/lib\"
