Your database is owned by root, and only root has write access. 您的数据库由root拥有，只有root具有写访问权限。 I'm betting you're running your app as the jack user, so you don't have write access. 我敢打赌，您正在以jack用户身份运行您的应用，因此您没有写权限。
Did you create this repo using the sudo command? 您是否使用sudo命令创建了这个仓库？ (sudo rails new or whatever). （sudo rails new或其他）。 Your whole app is owned by root. 您的整个应用程序由root拥有。
cd [your app's main directory]
chown -R jack:jack .

Make sure that the directory containing the database file is also writable to the user executing the CGI script 确保包含数据库文件的目录对于执行CGI脚本的用户也是可写的
