启动Guard时,我得到了这个输出:
$ guard
WARN: Unresolved specs during Gem::Specification.reset:
lumberjack (>= 1.0.2)
ffi (>= 0.5.0)
WARN: Clearing out unresolved specs.
Please report a bug if this causes problems.
这是什么意思,我该如何解决？
Guardfile的内容:
guard 'livereload' do
watch(%r{.+\.(css|js|html)$})
end
guard 'sass', :input => 'css', :style => :compressed, :extension => '.min.css'
我正在运行Mac OSX 10.6.4并安装了RVM.它到目前为止一直很棒,我真的很喜欢它让我在同一台机器上管理多个版本的rails和ruby而不会头疼的方式!
但是,我不想为每个设置安装某些宝石(例如乘客).有没有办法在宝石集之间分享宝石？我有一个1.8.7@rails2.3.8和1.9.2@rails3,我可以安装一下诸如passenger,mysql和capistrano之类的宝石,并且可以与所有版本一起使用吗？
当我尝试清理我的rails版本时 sudo gem cleanup rails
我收到以下错误:
Cleaning up installed gems...
Attempting to uninstall rails-2.3.5
Unable to uninstall rails-2.3.5:
Gem::InstallError: cannot uninstall, check `gem list -d rails`
Attempting to uninstall rails-1.2.6
Unable to uninstall rails-1.2.6:
Gem::InstallError: cannot uninstall, check `gem list -d rails`
gem list -d rails 结果是:
