基本上按照 https://gorails.com/setup/ubuntu/14.04 的安装方法是可以的。
第一个遇到的问题是 gem install rails 报错

Windows 7專業版（非旗艦版或企業版）除非買別的語言的重灌，不能安裝或改變顯示語言，所以如果本來是中文版就不能靠修改設置變英文版的。
從oracle.com下載java jdk（SE或EE）安裝，並沒有什麼問題。但是oracle java安裝過程中沒任何地方可以選擇使用非系統語言（比如選英文）。不過安裝好之後cmd如果java -help之類的會一堆『???????』，結果是因為我之前想全變英文，把windows設置的『非unicode程式的語言』改了。改回『繁體中文』就正常顯示，所以下面就是熟悉台灣cs專業詞彙的問題了。
eclipse基本下載了免安裝copy過去就好。不要忘了去『系統－控制台－系統及安全性－系統－進階系統設定－環境變數』裡面把$JAVA_HOME$和Path改了。
maven安裝後，要照著 http://maven.apache.org/download.cgi#Installation 去修改一堆『環境變數』。
eclipse運行時如果java報錯，顯示的也是中文（其實又是『???????』）。這邊去eclipse->window->preferences->General->workspace->Text file encoding那裡，從default的Cp1252改成UTF-8，錯誤信息就能正常顯示啦（比如『錯誤：找不到或無法載入主要類別 com.micareo.engine.AnalysisEngine』）。
