I've been trying to run a ruby file from terminal using:
ruby file_cleanse_auto.rb
but I get an error from mechanize:
/Library/Ruby/Site/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- mechanize (LoadError)
from /Library/Ruby/Site/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'
from file_cleanse_auto.rb:2:in `<main>'
In my ruby file I have:
require 'open-uri'
require 'mechanize'
I'm able to use mechanize without any errors with the Ruby shell (irb). It seems that it's only an issue when I'm trying to run ruby files from the command line.
The versions of ruby and mechanize I have installed are 2.0.0 and 2.7.5 respectively.
I've also tried adding mechanize to the Gemfile (with and without nokogiri). This is what it looks like now:
source "https://rubygems.org"
gem 'nokogiri'
gem 'mechanize'
After running:
bundle
I got:

Using mime-types-data 3.2016.0521

Bundle complete! 2 Gemfile dependencies, 14 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.
But I still get the same error when I try running the ruby file again. Does someone know how I could resolve this error? Thanks!
I had the same issue after recently installing ruby 2.4.
You should try gem install mechanize
This is because each ruby installation have an independent directory for gems. Hopefully that works.

I am using ruby version 2.3.3p222
Here is my Gemfile:
# Gemfile
source 'https://rubygems.org'
gem 'pry'
I run bundle and here is the resulting Gemfile.lock
Gemfile.lock
GEM
remote: https://rubygems.org/
specs:
coderay (1.1.2)
method_source (0.9.2)
pry (0.12.2)
coderay (~> 1.1.0)
method_source (~> 0.9.0)
PLATFORMS
ruby
DEPENDENCIES
pry
BUNDLED WITH
1.15.1
I then simply run a ruby script via ruby my_report.rb (this script is located in the same directory as Gemfile and Gemfile.lock). my_report.rb only has this in the file:
require 'pry'
Here is the error:
WARN: Clearing out unresolved specs.
Please report a bug if this causes problems.
/Users/<user>/.rvm/gems/ruby-2.3.3/gems/pry-rescue-1.4.5/lib/pry-rescue.rb:15: warning: method BaseHelpers#windows? is deprecated. Use Pry:Helpers::Platform.windows? instead

Question: What am I missing? How can I properly require in pry into my ruby script so that I can set breakpoints?
What eventually worked for me is I just uninstalled all of the pry versions I had installed via gem uninstall. Then: in my gemfile I specified a previous version of 0.11.3:
# Gemfile
source 'https://rubygems.org'
gem 'pry', '0.11.3'
I did bundle install and then ran my ruby script, and that worked for me.
Is there a way to install an earlier version of watir-webdriver including dependencies?
I've been running watir-webdriver for a while now, but just ran into problems today when installing on a new Windows environment.
The error is on the require "watir-webdriver". The first error line indicates that ruby is unable to load ffi
C:/Ruby21/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- ffi_c (LoadError)
It looks like the problem may be with the combination of gems, so am including the versions here:
bigdecimal (1.2.4)
childprocess (0.5.3)
ffi (1.9.5 x86-mingw32)
io-console (0.4.2)
json (1.8.1)
minitest (4.7.5)
multi_json (1.10.1)
psych (2.0.5)
rake (10.1.0)
rdoc (4.1.0)
rubyzip (1.1.6)
selenium-webdriver (2.43.0)
test-unit (2.1.3.0)
watir-webdriver (0.6.11, 0.6.10)
websocket (1.2.1)
If you know of a version that worked in the past, you can simple remove the current version and install an old one with the -v flag for gem install.
For example,
gem uninstall watir-webdriver
gem install watir-webdriver -v '= 0.4.0'
You can find the different available version on rubygems.org It will automatically install the proper dependencies.
Ruby Compass not working, code is bellow, and I've tried 10-20 methods on the web, any suggestions ?
In the screenshot you'll find an easier way to read the terminal dump of my gems and the error, in case you want to take something from there, you'll find the text under the screenshot
Thanks,

LoadError on line ["54"] of /Library/Ruby/Site/2.0.0/rubygems/core_ext/kernel_require.rb: cannot load such file -- rgbapng
Run with --trace to see the full backtrace
Fixed by installing the following compass extensions :
gem install compass-normalize
gem install compass-rgbapng
gem install toolkit
That did not fix it for me. However, I was able to fix it by reinstalling the compass gem using
gem uninstall compass
gem install compass
I think you can probably fix it even easier by just updating the compass gem to the latest version using gem update compass.
Note: If you use rails, you might also have to update your compass-rails gem. Otherwise, the compass watch command will start to hang. See this issue on github
I'm currently trying to install Webistrano on a freshly installed debian squeeze 64bits, but I'm facing some issues that I can't manage to solve.
Note: The machine is created under Xen environment, I don't think this affect the procedure however it seemed important to mention it.
Procedure:
Informations:
Ruby version: ruby 1.8.7 (2010-08-16 patchlevel 302) [x86_64-linux]
Rails version: `Rails 2.3.11
Path modifier with: /usr/lib/ruby/1.8:/var/lib/gems/1.8/bin
Rails env: development
Databases have been created
Databases setups for webistrano are, I believe correct (user/pass/path_to_sock_file)
So, here is what I did:
I first installed the 'basics' packages for such installation:
# apt-get install build-essential ruby rubygems libmysql-ruby libmysqlclient-dev libdbd-mysql-ruby mysql-server unzip rake
Then I have been downloading and extracting the project into /usr/src. After copying and configuring the files for email/databses setups (as suggested by https://github.com/peritor/webistrano), I continued by installing all the gems needed for the project:
bundle install
at this point, the command is stuck and isn't doing anything for an hour.
I know it can happen if the Gemfile is complicate, but it doesn't seem to be the case for me. (see the Gemfile following)
# cat Gemfile
source "http://rubygems.org"
gem 'bundler', "~>1.0.10"
gem "rails", "2.3.11"
gem "mysql"
gem "erubis"
gem "rake"
gem "syntax", "1.0.0"
gem "capistrano", "2.6.0"
gem "open4", "0.9.3"
gem "exception_notification", "2.3.3.0"
group :test do
gem "mocha", "0.9.8"
end
So deciding to go ahead I installed the gems by hands, which once finished gives:
# gem list *gems of Gemfile*
bundler (1.0.10)
rails (2.3.11)
mysql (2.8.1)
erubis (2.7.0)
rake (0.9.2.2)
syntax (1.0.0)
capistrano (2.6.0)
open4 (0.9.3)
exception_notification (2.3.3.0)
mocha (0.9.8)
So I believe everything should be working without having to run: bundle install
This is why I finally tried to create the database's structure with rake:
# rake db:migrate --trace
(in /usr/src/peritor-webistrano-a98ba6b)
rake aborted!
Bundler couldn't find some gems.Did you run `bundle install`?

According to rake error message, apparently some gems aren't properly installed, which seems weird to be, but I guess he can't find it.
So I double check with bundle tool:
# bundle check
Your Gemfile's dependencies could not be satisfied
Install missing gems with `bundle install`
# bundle show
Could not find gem 'mocha (= 0.9.8, runtime)' in any of the gem sources listed in your Gemfile.
And I'm stuck here, I just don't know how to continue.
I google around about mocha or gemfile issue, but haven't found much relevant.
I hope everything is clear and easy to understand as this is my first post.
Thanks for any reply/hints, also if I manage to evolve I'll try keeping you up to date!

Your bundle is updated! Use `bundle show [gemname]` to see where a bundled gem is installed.
I wan to run "simple" cron using whenever on Windows XP. So I installed whenever gem install whenever and then ran my cron.rb
require 'rubygems'
require 'whenever'
every 1.days, :at => '5:30am' do
command "puts now"
end
but it complained that
You don't have i18n installed in your application.
Please add it to your Gemfile and run bundle install
So I ran gem install i18n and now the same code gives me an error
C:\whenever>ruby cron.rb
cron.rb:4: undefined method 'every' for main:Object (NoMethodError)
Any idea how I can make whenever gem work?

This gem is a wrapper for the *nix utility cron. We can see in the gem source file command_line.rb line 75 that it uses 'crontab' shell command.
It will not work on a standard Windows install as this command is not available.
There are windows versions such as cronw, but I cannot say if these would be compatible with the whenever gem.
Alternatively you could run your long running task as a windows service. This article should get you started.
If you must use whenever/cron, perhaps because you are deploying on *nix, try downloading the Binami Rubystack VM - you'll be up and running in minutes.
