I have a very simple controller:
require 'net/ssh'
class MyController < ApplicationController
def foo
render :text => 'bar'
end
end
But when I request http://server:3000/my/foo I get:
MissingSourceFile in MyController#foo
no such file to load -- net/ssh
The gem is installed
> gem list net-ssh
*** LOCAL GEMS ***
net-ssh (2.0.11)
Also, I tried require 'net/ssh' in IRB, and it works.
MyController works fine on Windows, but fail on Ubuntu.
What can be wrong?
In a project I am working on we have used the config/environment.rb file to hold the gem require stuff. So
Rails::Initializer.run do |config|
# ...
config.gem 'net-ssh'
config.gem 'daemons'
config.gem 'slave'
config.gem 'vpim'
config.gem 'json'
# ...
end
I think you will require 'net-ssh' rather than 'net/ssh'. However we did run into a problem where have a hyphen in the name of the gem led to failures. Then we had to do
config.gem 'Ruby-IRC', :lib => 'IRC'
so that version maybe required for you. So that would be
config.gem 'net-ssh', :lib => 'net/ssh'
in case of rails 3.0 this solution if OK. add this in the yourapp/Gemfile,
gem 'net-ssh
就我而言,由于它是一个独立的ruby应用程序,所以我只需要rubygems。
您还可以使用Nic博士的“ gemsonrails”并将加载的宝石作为插件加载,请检查: http ://gemsonrails.rubyforge.org
I think, the original problem was that I used normal user instead of root:
$ gem install net-ssh
WARNING: Installing to ~/.gem since /usr/lib/ruby/gems/1.8 and
/usr/bin aren't both writable.
WARNING: You don't have /home/alex/.gem/ruby/1.8/bin in your PATH,
gem executables will not run.
So, I guess, rails could not find this gem.
