sudo apt-get install libsqlite3-dev libpcap-dev |
然后重新嘗試新的命令，即可解決上述錯誤
二、中文模式下切換回英文模式？
修改/etc/default/locale文件的語言值。
將lang zh_cn.utf-8修改為en_us.utf-8 , language zh_cn:zh修改為en_us:en
三、英文模式下開機自動啟動ibus中文輸入法。
英文模式下，ibus不能自動啟動。每次輸入中文都得手動啟動。這個讓人不能接受。google一下，兩種方法。
方法1：system settings->languange-support->keyboard input method system ->ibus
這種方法我沒試驗成功。如圖所示，選擇了沒有保存按鈕。我以為是默認保存的。但是關了在打開發現還是沒有選擇上。有可能語言包沒有按完整的語言，每次進入語言設置，都會提示語言包沒有安裝完整。
方法2：添加ibus設置為開機啟動的應用
system->preferences->startup application
-d 的意思是讓ibus在后臺運行
