Centos 部署rails应用遇到的一些问题
1. 在centos中安装Nokogiri是遇到问题
libxml2 is missing. please visit <http://nokogiri.org/tutorials/installing_nokogiri.html>
解决方法如下:
$ sudo yum install -y libxml2 libxml2-devel libxslt libxslt-devel
2. openssl 问题
$ ... :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
