无法使用 bundle install 安装 mysql2。
我询问是因为一些网站和博客展示了如何解决由于 ssl、zstd 引起的问题，但我找不到由 zlib 引起的解决方案。有其他人遇到过同样的问题吗？
顺便说一下，我是在本地运行 bundle install，而不是在 Docker 上。
- 操作系统：Ventura（13.3.1）
- Xcode：14.3
- Ruby：3.1.4
- Rails：6.1
- Mysql2：0.5.5
已经完成：
brew install mysql, openssl@3, zstd, zlib
以下是日志输出。

An error occurred while installing mysql2 (0.5.5), and Bundler cannot continue.
In Gemfile:
mysql2
我尝试过的
・在执行brew install zlib之后，将以下内容添加到.zshrc中
export LDFLAGS="-L/opt/homebrew/opt/zlib/lib"
export CPPFLAGS="-I/opt/homebrew/opt/zlib/include"
export PKG_CONFIG_PATH="/opt/homebrew/opt/zlib/lib/pkgconfig"
・在未在brew info zlib中显示但在此处答案中提到的内容中添加以下内容。
export DYLD_LIBRARY_PATH=/opt/homebrew/opt/zlib/lib:$DYLD_LIBRARY_PATH
・通过 xcode-select --install 重新安装 命令行工具
结果：
- 输出日志未更改。
- 无法安装
mysql2。
/opt/homebrew/opt/mysql。 - qounmebundle config mysql2 ...来设置。 - tadman
