我正在尝试使用RubyGems在我的Mac (gem install jekyll)上安装Jekyll，但我遇到了下面的错误。
Building native extensions. This could take a while...

我尝试了brew install openssl，但它说openssl已经安装，我也尝试了gem install eventmachine -- --with-cppflags=-I/usr/local/opt/openssl/include，但我得到了相同的错误'openssl/ssl.h' file not found。
有人能指出如何解决这个问题吗?
您可能需要先运行brew link --force openssl。
Thengem install eventmachine -- --with-cppflags=-I/usr/local/opt/openssl/include
我有同样的问题，这对我有效:
gem install eventmachine -v '1.2.7' -- --with-cppflags=-I/usr/local/opt/openssl/include
我必须指定版本。没有它，它仍然失败🤷
