🧀 gem install 遇到 eventmachine(1.2.7) 安装不成功问题

问题

今天我在 gem install jekyll bundle 的时候，一直出现一个问题就是

/Users/mmmmmcclxxvii/.gem/ruby/3.4.1/gems/jekyll-4.3.4/lib/jekyll.rb:26: warning: logger was loaded from the standard library, but will no longer be part of the default gems starting from Ruby 3.5.0.
You can add logger to your Gemfile or gemspec to silence this warning.

然后我在 eventmachine(1.2.7) installation issue on Intel mac with ruby 3.3.0 得到解决方案

原因

如果你也遇到类似的问题，请先执行

ruby -rrbconfig -e 'puts RbConfig::CONFIG["CXX"]'

如果结果是false 那么基本上你需要重新安装 XCode CLT 和 ruby 来解决上述的问题

正常的结果应该是

解决方案

# Uninstall XCode CLT
% sudo rm -rf /Library/Developer/CommandLineTools

# Reinstall XCode CLT
% sudo xcode-select --install
% softwareupdate --all --install --force

# uninstall ruby
# reinstall ruby

建议使用 ruby-install 和 chruby 来安装管理 ruby
