in `require': no such file to load -- openssl (LoadError)

解决方法如下:

下载1.9.2源文件,执行以下命令

$ cd ~/Downloads/ruby- 1 . 9 . 2 -p180/ext/openssl (assuming you extracted the ruby tar to ~/Downloads)
$ ruby extconf.rb && make && sudo make install

 

If you’ve compiled Ruby from source, you might get this error when executing script/console:

 

/usr/local/lib/ruby/1.8/irb/completion.rb:10:in `require': no such file to load -- readline (LoadError)

 

One way of fixing this is to compile readline, which is distributed along with the Ruby source:

 

 cd /opt/src/ruby-1.8.5-p2/ext/readline
 ruby extconf.rb
 make
 sudo make install
