I'm using Ubuntu Server 10, Ruby 1.9.2

当我尝试要求 'mongo'

它给了我这个错误:

推荐答案

您需要两件事:OpenSSL 本身和 OpenSSL 的 ruby​​ 绑定.第一部分正如 Yossi 所说:

You need two things: OpenSSL itself and the ruby bindings for OpenSSL. The first part is as Yossi said:

sudo apt-get install libssl

第二个取决于你如何安装 ruby​​.我从您问题中的路径猜测您是从源代码编译 ruby​​ 的.在这种情况下，您首先需要确保您拥有 openssl 标头:

The second depends on how you install ruby. I'm guessing from the paths in your question that you compiled ruby from source. In which case you first need to make sure you have then openssl headers:

sudo apt-get install libssl-dev

那么在你编译ruby的时候它应该会被自动拾取.如果您不想重新编译 ruby​​，您应该能够通过

then it should be picked up automatically when you compile ruby. If you do not want to recompile ruby, the you should be able to build the OpenSSL bindings by

• cd 到包含 ruby​​ 源代码的文件夹
• cd 到 ext/openssl
• ruby extconf.rb
• make &&须藤安装
