Estoy tratando de instalar Jekyll en mi Mac ( gem install jekyll ) usando RubyGems pero me encuentro con el siguiente error.

 Building native extensions. This could take a while... ERROR: Error installing jekyll: ERROR: Failed to build gem native extension. current directory: /Users/nikhilanand/.rvm/gems/ruby-3.0.2/gems/eventmachine-1.2.7/ext /Users/nikhilanand/.rvm/rubies/ruby-3.0.2/bin/ruby -I /Users/nikhilanand/.rvm/rubies/ruby-3.0.2/lib/ruby/3.0.0 -r ./siteconf20210816-54247-5zijii.rb extconf.rb checking for -lcrypto... yes checking for -lssl... yes checking for openssl/ssl.h... yes checking for openssl/err.h... yes checking for rb_trap_immediate in ruby.h,rubysig.h... no checking for rb_thread_blocking_region()... no checking for rb_thread_call_without_gvl() in ruby/thread.h... yes checking for rb_thread_fd_select()... yes checking for rb_fdset_t in ruby/intern.h... yes checking for rb_wait_for_single_fd()... yes checking for rb_enable_interrupt()... no checking for rb_time_new()... yes checking for inotify_init() in sys/inotify.h... no checking for __NR_inotify_init in sys/syscall.h... no checking for writev() in sys/uio.h... yes checking for pipe2() in unistd.h... no checking for accept4() in sys/socket.h... no checking for SOCK_CLOEXEC in sys/socket.h... no checking for sys/event.h... yes checking for sys/queue.h... yes checking for clock_gettime()... yes checking for CLOCK_MONOTONIC_RAW in time.h... yes checking for CLOCK_MONOTONIC in time.h... yes CXXFLAGS= -Wall -Wextra -Wno-deprecated-declarations -Wno-ignored-qualifiers -Wno-unused-result -Wno-address creating Makefile current directory: /Users/nikhilanand/.rvm/gems/ruby-3.0.2/gems/eventmachine-1.2.7/ext make DESTDIR\= clean current directory: /Users/nikhilanand/.rvm/gems/ruby-3.0.2/gems/eventmachine-1.2.7/ext make DESTDIR\= compiling binder.cpp In file included from binder.cpp:20: ./project.h:119:10: fatal error: 'openssl/ssl.h' file not found #include <openssl/ssl.h> ^~~~~~~~~~~~~~~ 1 error generated. make: *** [binder.o] Error 1 make failed, exit code 2 Gem files will remain installed in /Users/nikhilanand/.rvm/gems/ruby-3.0.2/gems/eventmachine-1.2.7 for inspection.

brew install openssl pero dice que openssl ya está instalado, y también probé gem install eventmachine -- --with-cppflags=-I/usr/local/opt/openssl/include pero recibo el mismo error 'openssl/ssl.h' file not found .

¿Alguien podría señalar cómo solucionar este problema aquí?
