Rails服務器將無法運行WEBrick

Question

我是一個新手，嘗試按照Rails教程進行操作，並已從http://railsinstaller.org/成功運行了安裝例程

我還安裝了mysql

我已經使用命令> rails new simple_cms -d mysql

這似乎運行成功

當我運行Rails服務器

這是下面的輸出-似乎沒有在端口3000上啟動WEBrick

非常感謝

我有同樣的問題。 因為在Mac OS X上，mysql通常安裝在/usr/local/mysql ，所以您需要在/usr/lib手動設置libmysqlclient的路徑。

在終端中運行：

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib
