爲什麼需要蒙戈給我LoadError：沒有這樣的文件來加載 - OpenSSL的

Question

我使用Ubuntu的服務器10，紅寶石1.9.2

當我試圖要求「蒙戈」

它給了我這個錯誤：

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'

Answer 1

您需要兩件事：OpenSSL本身和OpenSSL的ruby綁定。第一部分是因爲Yossi說：

sudo apt-get install libssl 

第二個取決於你如何安裝ruby。我從你的問題的路徑猜測你是從源代碼編譯ruby的。在這種情況下，你首先需要確保你有那麼OpenSSL的頭：

sudo apt-get install libssl-dev 

那麼它應該會自動在編譯紅寶石回升。如果你不想重新編譯紅寶石時，你應該能夠通過

• CD打造的OpenSSL綁定到包含紅寶石源
• cd到EXT/OpenSSL的文件夾
• ruby extconf.rb
• make && sudo make install
