我正在使用linuxbrew在ubuntu上安装postgresql:
brew install postgresql
它似乎工作正常,但之后因为我第一次安装PostgreSQL我尝试创建一个数据库:
initdb /usr/local/var/postgres -E utf8
但它返回为:
initdb: command not found
我试着运行命令 sudo but that doesn't helped
我真的很擅长轨道和编程,我正在努力教自己.我用bootstraps创建了一个简单的rails应用程序.面临的问题是我添加了带固定顶部的bootstrap导航栏,然后我添加了
body {
padding-top: 60px;
}
但我陷入了错误:
Sass::SyntaxError in Pages#dashboard
