gem eventmachine fatal error: ‘openssl/ssl.h’ file not found

brew –prefix openssl
/usr/local/opt/openssl@3/include/openssl
ls /usr/local/opt/openssl@3/include/openssl

gem install eventmachine – –with-cppflags=-I$(brew –prefix openssl)include

sudo gem install eventmachine – –with-cppflags=-I$(brew –prefix openssl)include

都失败了因为路径不对：
sudo bundle config build.eventmachine –with-cppflags=-I$(brew –prefix openssl)//include

sudo bundle install
成功

% gem install eventmachine – –with-cppflags=-I$(brew –prefix openssl)//include
Building native extensions with: ‘–with-cppflags=-I/usr/local/opt/openssl@3//include’

Hello! This is where you manage which Jekyll version is used to run.

When you want to use a different version, change it below, save the

file and run bundle install. Run Jekyll with bundle exec, like so:

#

bundle exec jekyll serve

#

This will help ensure the proper Jekyll version is running.

Happy Jekylling!

gem “jekyll”, “~> 4.2.1”

This is the default theme for new Jekyll sites. You may change this to anything you like.

gem “minima”, “~> 2.0”
#gem ‘maruku’, ‘~> 0.7.3’

If you want to use GitHub Pages, remove the “gem “jekyll”” above and

uncomment the line below. To upgrade, run bundle update github-pages.

gem “github-pages”, group: :jekyll_plugins

If you have any plugins, put them here!

group :jekyll_plugins do
gem “jekyll-feed”, “~> 0.15.1”
end

gem “jekyll-paginate”,”~> 1.1.0”
gem “pygments.rb”,”~>1.1.2”

Windows does not include zoneinfo files, so bundle the tzinfo-data gem

gem ‘tzinfo-data’, platforms: [:mingw, :mswin, :x64_mingw, :jruby]
