我試圖安裝taglib-ruby但繼續得到同樣的錯誤：在Ubuntu 12.04上安裝taglib-ruby gem時缺少libstdC++？
[email protected]:~$ sudo gem install taglib-ruby
Building native extensions. This could take a while...
ERROR: Error installing taglib-ruby:

You must have libstdc++ installed.

necessary libraries and/or headers. Check the mkmf.log file for more

mkmf.log說以下內容：

我跟着自述文件中的說明，安裝libtag1-dev和雙重檢查如果我安裝了libstdC++（我甚至在Ubuntu軟件中心查看，如果我錯過了一個文件）。 我發現的唯一類似問題是this one，但我已經試過明確定義opt-dir和opt-include，這也沒有幫助。
我不得不承認，我對這個話題甚至是Ubuntu並不是很熟悉，所以我可能只是忽略了或者完全錯過了關於錯誤信息的一些明顯的東西。
嘗試安裝'build-essentials'，它應該帶有一個C++開發環境。 – TeTeT
非常感謝，這工作完美:) – kah
