It’s easy; just do the following:

    rvm implode

or

    rm -rf ~/.rvm

And don’t forget to remove the script calls in the following files: 

 - `~/.bashrc` 
 - `~/.bash_profile` 
 - `~/.profile`

And maybe others depending on whatever shell you’re using.

I am trying to debug some inconsistent behaviour I am seeing in an application that gets its primary data from the Internet.  I don&#39;t see the issues in the simulator, just on the device, so I&#39;d like to reproduce the network and connectivity environment in the simulator.

Is there a way of disabling the network in the simulator?

(I am connecting to the Mac remotely to code, and there isn&#39;t any other choice right now, so disabling the OS network isn&#39;t an option).



Is it possible to disable the network in iOS Simulator?

Why are some rake tasks not listed by `rake -T`? Like `db:migrate:reset`? I can execute it without a problem, but why is it not listed there? Is there a way to get a real full list of rake tasks?

&lt;pre&gt;
% rake -T
(in /home/zeus/projects/my_project)
rake about              # List versions of all Rails frameworks and the environment
rake db:create          # Create the database from config/database.yml for the current Rails.env (use db:create:all to create all dbs in the config)
rake db:drop            # Drops the database for the current Rails.env (use db:drop:all to drop all databases)
rake db:fixtures:load   # Load fixtures into the current environment&#39;s database.
rake db:migrate         # Migrate the database (options: VERSION=x, VERBOSE=false).
rake db:migrate:status  # Display status of migrations
rake db:rollback        # Rolls the schema back to the previous version (specify steps w/ STEP=n).
rake db:schema:dump     # Create a db/schema.rb file that can be portably used against any DB supported by AR
rake db:schema:load     # Load a schema.rb file into the database
rake db:seed            # Load the seed data from db/seeds.rb
rake db:setup           # Create the database, load the schema, and initialize with the seed data (use db:reset to also drop the db first)
rake db:structure:dump  # Dump the database structure to an SQL file
rake db:version         # Retrieves the current schema version number
rake doc:app            # Generate docs for the app -- also availble doc:rails, doc:guides, doc:plugins (options: TEMPLATE=/rdoc-template.rb, TITLE=&quot;Custom Title&quot;)

rake log:clear          # Truncates all *.log files in log/ to zero bytes
rake middleware         # Prints out your Rack middleware stack
rake notes              # Enumerate all annotations (use notes:optimize, :fixme, :todo for focus)
rake notes:custom       # Enumerate a custom annotation, specify with ANNOTATION=CUSTOM
rake rails:template     # Applies the template supplied by LOCATION=/path/to/template
rake rails:update       # Update both configs and public/javascripts from Rails (or use just update:javascripts or update:configs)
rake routes             # Print out all defined routes in match order, with names.
rake secret             # Generate a crytographically secure secret key (this is typically used to generate a secret for cookie sessions).
rake spec               # Run all specs in spec directory (excluding plugin specs)
rake spec:acceptance    # Run the code examples in spec/acceptance
rake spec:controllers   # Run the code examples in spec/controllers
rake spec:helpers       # Run the code examples in spec/helpers
rake spec:lib           # Run the code examples in spec/lib
rake spec:mailers       # Run the code examples in spec/mailers
rake spec:models        # Run the code examples in spec/models
rake spec:rcov          # Run all specs with rcov
rake spec:requests      # Run the code examples in spec/requests
rake spec:routing       # Run the code examples in spec/routing
rake spec:views         # Run the code examples in spec/views
rake stats              # Report code statistics (KLOCs, etc) from the application
rake test               # Runs test:units, test:functionals, test:integration together (also available: test:benchmark, test:profile, test:plugins)

rake time:zones:all     # Displays all time zones, also available: time:zones:us, time:zones:local -- filter with OFFSET parameter, e.g., OFFSET=-6
rake tmp:clear          # Clear session, cache, and socket files from tmp/ (narrow w/ tmp:sessions:clear, tmp:cache:clear, tmp:sockets:clear)
rake tmp:create         # Creates tmp directories for sessions, cache, sockets, and pids
&lt;/pre&gt;


Why is rake db:migrate:reset not listed in rake -T?

When learning Ruby, I noticed that in all the examples there are no semicolons. I am aware that this is perfectly fine as long as each statement is on its own line. But what I am wondering is, *can* you use semicolons in Ruby?



Can you use semicolons in Ruby?

I tried `rake stats` but that seems highly inaccurate. Perhaps it ignores several directories?

How can I uninstall Ruby 1.9.2dev (2010-07-02) [i486-linux]
on ubuntu?
 Need to reinstall - please help

How can I uninstall Ruby on ubuntu?

I want to switch between rails 2.3.10 as the &quot;active&quot; gem for my OS, so that I can invoke it at the command line.

Is it possible to do this? I&#39;m not using rvm. Maybe it&#39;s time to start.

I tried `gem install rails --version=2.3.10`, but that just makes sure that version of the gem is installed, it doesn&#39;t put it in `/usr/bin/rails`.

(I do already use bundler for my apps -- but haven&#39;t needed any precise control over gems at the OS level until now)

How do I &quot;activate&quot; a different version of a particular gem?

I&#39;ve installed rvm as a way of making sure that my local development version of ruby is the same as my server&#39;s for a particular app i work on (ruby 1.8.7).  I&#39;ve done this, and installed ruby 1.8.7 ok.  However, when i try to start the rails console i get this error:

    Readline was unable to be required, if you need completion or history install readline then reinstall the ruby.
    You may follow &#39;rvm notes&#39; for dependencies and/or read the docs page http://rvm.beginrescueend.com/packages/readline/ . Be sure you &#39;rvm remove X ; rvm install X&#39; to re-compile your ruby with readline support after obtaining the readline libraries.
    Couldn&#39;t load Wirble: no such file to load -- wirble

I&#39;ve read the notes on the page that error refers to (http://rvm.beginrescueend.com/packages/readline/), and followed the instructions, which involve basically installing readline, uninstalling ruby 1.8.7, then installing ruby 1.8.7 again with readline support.  (actually that page uses ruby 1.9.2 as an example but i&#39;m assuming it should work with 1.8.7 as well.  Perhaps that&#39;s not the case).

But, i still get the same error.  Has anyone else been through this and figured it out?  
Grateful for any advice - max

Problems with the rails console, RVM and readline

My current version of ruby is `ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.5.0]` but I want to update it to the latest patch level using rvm. How can I do this?



How do I upgrade my ruby 1.9.2-p0 to the latest patch level using rvm?

I read &quot;https://stackoverflow.com/questions/4361645/relationships-between-rubygems-bundler-and-rvm&quot; before asking it again. 

Well, there are many questions like this, but people who answered say they work with Rubygems, RVM and Bundler, and they have not explained how each of these work in isolation. 

I am really confused with how the three work in isolation when we are installing gems. Please do not tell me how you work, which will help me, but I won&#39;t learn what is happening when we play with them.

My confusion can be broken down into these questions. Where is a gem installed when:

1. I just have Rubygems (without RVM or Bundler)?
2. Rubygems and RVM are installed?
3. Rubygems, RVM and Bundler are installed?

Please help me understand this stuff with either resources on the web or by your detailed answers.
