ruby – 为什么要求mongo给我LoadError：没有这样的文件要加载 – openssl

我正在使用Ubuntu Server 10,Ruby 1.9.2

当我试图要求’mongo’时

它给了我这个错误：

irb(main):001:0> require 'mongo'
LoadError: no such file to load -- openssl
    from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'

解决方法

您需要两件事：OpenSSL本身和OpenSSL的ruby绑定.第一部分是Yossi说的：

sudo apt-get install libssl

第二个取决于你如何安装ruby.我猜你的问题中的路径是你从源代码编译ruby.在这种情况下,您首先需要确保您有openssl标头：

sudo apt-get install libssl-dev

然后它应该在编译ruby时自动拾取.如果您不想重新编译ruby,那么您应该能够构建OpenSSL绑定

> cd到包含ruby源的文件夹> cd到ext / openssl> ruby​​ extconf.rb> make&& sudo make install
