安裝Gherkin 2.1.5的故障排除

Question

我正在嘗試安裝Gherkin 2.1.5，實際上它是https://github.com/opencongress/opencongress的依賴項。 我在代碼的根目錄中使用bundle install進行安裝，安裝了大約20-30個軟件包，現在我已經堅持了。 我在跑步：

Linux 3.2.0-27-generic #43-Ubuntu SMP
Linux Mint 13 Maya

一旦停止安裝，這是輸出。

Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/gherkin-2.1.5 for inspection.

我從來沒有在ruby中編程，所以我對整個安裝過程中的東西都有點脫節。 我剛剛想出如何安裝redcloth並認為我很好。 謝謝你的建議。

Answer 1

gem install gherkin -v '2.1.5' -- --with-cflags=-w

為我做了訣竅。
