Question

我认为我的设置有问题。

我正在尝试按照本指南安装Rubber： https://github.com/rubber/rubber/wiki/Quick-Start

看来我正确安装了橡胶......

$ sudo gem install rubber
$ Successfully installed rubber-2.7.4
$ 1 gem installed

但我不能援引它......

$ rubber vulcanize complete_passenger_postgresql
$ /usr/lib/ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find rubber (>= 0) amongst [actionmailer-4.0.3, actionmailer-4.0.2

我很困惑。我使用rvm并且每个宝石都应该存储在〜/ .rvm / gems中。为什么/usr/lib/ruby目录完全参与？

任何帮助都会很棒

我明白了！

问题是我使用的是rvm，但我仍然用sudo为我的宝石加前缀即。

gem install ...

和 sudo gem install ...

完全不同的环境。看这篇文章： Why do "gem" and "sudo gem" have different installation directories?

我是通过“sudo gem install”安装的，但是我在没有sudo的情况下调用了橡胶命令。

橡胶安装但不可用？
