無法運行WEBrick

試圖在這裏學習Ruby on Rails並遵循視頻教程，但似乎無法獲得運行環境。我在使用rails new project_name創建項目的時候，但是當我去運行服務器rails server時，我實際上無法使其運行。無法運行WEBrick

我得到的消息如下：

drew$ rails server

它看起來像你的mysql2寶石沒有正確安裝。 Take a look at this question。不知道你的環境是什麼樣的，但如果你在窗戶上看看第二個答案。我認爲那將會適用於你。

在沒有你的PATH libmysqlclient.18.dylib。您需要將mysql lib目錄添加到環境變量：DYLD_LIBRARY_PATH（Mac OS X）或 LD_LIBRARY_PATH（Linux）。

說出你的mysql安裝在/usr/local/mysql/，請執行下列操作：

# Linux 
export LD_LIBRARY_PATH="/usr/local/mysql/lib/:$LD_LIBRARY_PATH" 
# Mac OS X 
export DYLD_LIBRARY_PATH="/usr/local/mysql/lib/:$DYLD_LIBRARY_PATH"
