-----
Don't know how to set rpath on your system, if MySQL libraries are not in path mysql2 may not load

Setting libpath to /opt/homebrew/Cellar/mysql/8.0.26/lib

creating Makefile

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.

In Gemfile:
  mysql2

似乎“捆绑”尝试访问ld: warning: directory not found for option '-L/usr/local/opt/openssl/lib/'

openssl 路径开启时：opt/homebrew/opt/openssl@1.1/lib/

如何将'-L/usr/local/opt/openssl/lib/' 更改为opt/homebrew/opt/openssl@1.1/lib/

有人可以帮忙吗？

【解决方案1】：

如果您使用的是 Linux，请安装以下 Linux 软件包：

sudo apt update
sudo apt install git curl libssl-dev libreadline-dev zlib1g-dev autoconf bison build-essential libyaml-dev libreadline-dev libncurses5-dev libffi-dev libgdbm-dev

许多 RubyGems 需要它们的本地库。

然后再次运行bundle install。

我在 Rails 6.1.4.1 (Ruby 3.0.1p64) 中也发生了同样的事情。

我已经尝试执行brew info openssl，然后按照显示一些指南。

echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> /Users/user/.bash_profile
