我不知道是否安装了,也不知道如何确认。如何使group命令工作?或者如何安装gem pg和rails\u 12factor?
有什么帮助吗?您不希望从终端以命令的形式运行
group…
,而是将该代码块放在rails应用程序的Gemfile
中
Gemfile
group :production do
gem 'pg', '0.15.1'
gem 'rails_12factor', '0.0.2'
end
然后运行bundle
命令
如果您仍然无法以这种方式编译
pg
gem,那么您需要确保安装了xcode命令行工具(假设您使用的是OSX)。要安装这些,只需从终端运行xcode选择--install
,并按照提示进行操作。您正在运行ubuntu吗?看起来您需要此库:
sudo apt-get install libpq-dev
它在Ubuntu上帮助了我我没有使用UBTO,我使用的是OSX 10.6。苏多做什么?啊。然后看起来您需要命令行工具。要安装它们:
xcode选择--install
;然后再试一次sudo
以超级用户权限运行命令,并且需要管理密码。我是Ubuntu用户,它为我工作,非常感谢!
sudo apt-get install libpq-dev
sudo apt-get install libpq-dev
