I am switching from DJANGO to Rails, but i don't know how to install RVM in PROD environment.
My PROD server is without internet connection, and not possible connect even for a while. And i cannot find a standalone install package of RVM.
Is there any solution for offline RVM installation?
BTW, can rails be installed without internet?
I just spent some time and build a tutorial for the offline mode: https://rvm.io/rvm/offline - it's the first version so feel free to improve it here: https://github.com/wayneeseguin/rvm-site/blob/master/content/rvm/offline.md (Edit button).
Additionally to my first answer another way to do it would be to compile ruby on online machine, then package it, unpack on the other end and add it to PATH on the offline machine.
Way 1 - only Ruby
curl -L https://get.rvm.io | bash -s stable
source $HOME/.rvm/scripts/rvm
rvm install 1.9.3 --movable
rvm prepare 1.9.3
Some information will be displayed, including file name. Copy it to the offline machine and unpack it there, then just add it to PATH:
echo 'PATH=$PATH:${unpacked_dir}/bin' >> ~/.bashrc
Way 2 - whole RVM:
curl -L https://get.rvm.io | sudo bash -s stable
source /usr/local/rvm/scripts/rvm
rvm use 1.9.3 --install
gem install rails -v 3.2.8
rails new rails3
rvm use 1.8.7 --install
gem install rails -v 2.3.14
rails new rails2
tar czf rvm_and_ruby.tgz /usr/local/rvm /etc/rvmrc /profile.d/rvm.sh
Unpack on the offline end:
cd /
sudo tar xzf rvm_and_ruby.tgz
And open a new terminal.
check http://railsinstaller.org/ (for windows and mac) .After then change environment into production mode . In linux this works export RAILS_ENV=production .
If you are using a linux OS, you can always package the app as a debian or rpm archive which will include rails and the dependent gems referred in your Gemfile. The advantage with this approach is that you can also configure the archive to setup external dependencies like any other deb or rpm package. One of my recent projects came up with a in house solution. Now there are tools like pkgr
You can download a standalone RVM package here: https://github.com/wayneeseguin/rvm/tags
You can reference the RVM installer script for details on what an RVM install does. Simply replace the network calls with references to some local file, and you should be good to go.
That said, once RVM is installed, I'm not sure if it'll let you do an offline Ruby install easily, but this should get you started.
Well you need to download the source code from somewhere to install RVM, Rails. Not very clear as to how your Prod environment lacks an internet connection. Could you please give more details?

I've installed Ruby on a Windows computer
After Setting Up Ruby Installer What Command line tools do you use?

I've tried the command
rvm use 1.9.3
using the command prompt ruby and rails
I get the error message
rvm is not a recognised command
From RVM’s FAQ:
Does RVM work on windows? Will it in the future?
NO. If you would like to manage multiple versions of ruby on windows please use pik which is an excellent tool by Gordon Thiesfeld. You can find it on GitHub. There are plans to include windows support in RVM 2.0.
https://rvm.io/support/faq#does-rvm-work-on-windows-will-it-in-the-future
Doing Rails development on Windows is a little bit more of a challenge and you may run into some annoyances, but it's definitely possible.
Uru worked well for me as a nice alternative to RVM, which doesn't run on Windows. However, if you just want to have one version of Ruby installed on your computer and work with it, you don't even need to bother with Uru.
Windows is not the best environment to develop with Ruby ...
RVM doesn't work and PIK hasn't updated for more than 2 years..

This installer doesn't install RVM. It installs Ruby interpreter and Rails.
Since you've installed it, I assume you have your Ruby and libraries for it (called gems) rails and bundler. Execute gem list in your shell to verify (it should output a looong list).
Then you should create a new Rails project:
rails new project_name
...and then go into the folder that got created
cd project_name
bundle what you have:
bundle install
...and launch the server to see if it works:
rails server
or
rails s
You will likely run into issues with tzinfo gem if you're on 64-bit Windows, but that can be easily fixed by searching around StackOverflow, it's been discussed.
Gool luck to you. Developing Rails applications in Windows proved to be hard to me. Consider launching a virtual machine (using, for example, VirtualBox) with Linux aboard. That's what you could do in Linux:
install RVM as the site suggests:
curl -sSL https://get.rvm.io | bash -s stable
install the latest MRI available - feel free to replace ruby with the version you need, like rvm install 2.0.0
rvm install ruby
select and set as default the Ruby you need, you've tried a similar line apparently with Ruby 1.9.3
rvm --default use ruby
another long process
gem install rails
rails new project_name
(same as described above)
cd project_name
bundle install
rails s
That should work, and that's what you've probably seen. Again, I highly recommend using Linux in VirtualBox (or anything similar) for Rails development. A native Linux installation could only be a better environment, but most people are not ready for this just yet.
Yesterday I installed ruby and rails using rvm in ubuntu 12.04 and it is working fine and also created a sample application.But today when i run
ruby -v
it is showing like
The program 'ruby' can be found in the following packages:
ruby1.8
ruby1.9.1
Try: apt-get install
You probably forgot the latest step when installing RVM. It is mentioned at the end of the install process but easily overlooked. It boils down to this:
Make sure you have the following lines at the bottom of ~/.bashrc:
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
source "$HOME/.rvm/scripts/rvm"
This will load RVM right after you open a new shell. Without it, RVM is not 'activated' and when you type ruby it will use the version installed through your OS package manager and not the version installed through RVM.
Run rvm list. If it shows rubies then everything is ok and go to step 2.(if any problems then try reinstall rvm)(if it shows empty rubies list, then install ruby using rvm again(rvm install 2.1.1)
Specify current rvm ruby by one of the following ways:
Specify ruby version manually by running rvm use 2.1.1 for ruby2.1.1. This way you have to call this command every time you open a terminal (see next ways if this doesn't suit you)
Set default ruby version. See here.
Use .rvmrc file in any directory(see here how) to make rvm change ruby version when you open this directory.
Probably that is your case.
In addition to zwipple's answer, if you can also load rvm for once using following command:
source ~/.rvm/scripts/rvm
ruby -v
=> #your ruby version
Running OSX Mavericks, ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin13.0], rvm 1.25.23 (master), and rails-4.1.0 (allegedly)
I'm working through the railsapps.org book on learning rails and made it about 1/2 way through yesterday. When I stopped for the day, I closed out iTerm2 and shut off the Macbook Pro. Today, I powered up, opened iTerm, navigated to my working directory (~/rubyonrails/learn-ruby) and entered rails -v.
I see this:
`Rails is not currently installed on this system. To get the latest version, simply type:
$ sudo gem install rails
You can then rerun your "rails" command.`
So I run sudo gem install rails and it shows that it has installed rails-4.1.0. Now rails -v still gives me the same error message above.
I tried also running rvm use ruby-2.1.1#learn-rails first and I still get the error message.
So I'm a little stuck and I can't figure out what to do to get rails working. Also, how do I go about setting up the bash environment such that I don't have to go through this each time? It would be nice to nav to my working directory and just start work without having to do a bunch of re-installation and reconfiguration each time.
Regards,
Jeff
please type in your shell:
$ bash --login
and then repeat your commands.
rails -v
Also try to call it with the full path:
like:
/your/path/to/rails -v
I think that the shell just doesn't know where rvm/rails etc is located.
You can solve this by entering:
$ source ~/.rvm/scripts/rvm
When you switch to the ruby-2.1.1#learn-rails ruby/gemset combo, and do gem list, what do you see?
The way people usually use rvm is to have every project folder specify the ruby & gemset it uses (they don't all have to be different). This is done with files called .ruby-version and .ruby-gemset. These should contain, in your case, ruby-2.1.1 and learn-rails respectively.
Set these if you haven't already, then leave the folder and enter it again. Then do bundle install to install the gems for the project into the rvm/gemset combo.
Your problem is that you ran
sudo gem install rails
The error message telling you to do this comes from your system Ruby, which doesn't know that you want to use RVM.
RVM installs gems into your user-space directory. By using sudo, you're bypassing this and installing it into (effectively) the superuser space, i.e. globally.
If you instead just run
gem install rails
then you'll be using RVM's copy of the gem utility rather than the globally installed version.
I'm new to Ruby on Rails and have just set it up in Ubuntu Linux following instructions I found here. Specifically,
As s.m. said, I uninstalled everything, then I opened another terminal session as a normal user and run:
bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
then i run source /home/my-desktop-username/.rvm/scripts/rvm as a normal user NOT ROOT
then i run rvm requirements as a normal user. Then I copy the requirements and close the session, open a root session and install the requirements using sudo
Then I close the session and open a normal user session and run rvm install ruby-1.9.3-p125 if you run this command as root, it will say that rvm is not installed and will suggest that you install it using sudo apt-get install rvm Don't do that!
So basically I had two problems, the tutorials that i followed didn't say that i should run
source /home/my-desktop-username/.rvm/scripts/rvm and didn't say that I should not run rvm as root, s.m told me that. Thanks to everyone, especially to s.m
That works well, but I will have to remember to
source .rvm/scripts/rvm
every time I open a terminal to work with Ruby on Rails.
Is there a way to permanently tell Ubuntu to look in .rvm for all the Ruby stuff?
You need to add your
source .rvm/scripts/rvm
into your $HOME/.bashrc file; read the advanced bash scripting guide for more.
Ok, so I decided I'd be cool and try to use Rails3 that's in beta. Then, things were getting hard to manage so I got rvm. I installed ruby 1.9.2-head in rvm and things were working, and then a computer restart later rails wouldn't start up. So I figured I'd just try running the system ruby and start rails in it. same error. Then, I uninstalled rails3 and got rails: no such file or directory type errors..
So now I'm royally screwed because rails2 is still installed but will not uninstall because of invisible dependencies, along with a lot of other random gems. How do I completely clear out all ruby gems and such so I can start anew?
I've recently had to so just this. I had built up alot of cruft with my system installed ruby and gems and wanted to clean all that out and move everything over to run under rvm for various projects.
1. Clean up old and busted
First thing I did, before messing with rvm (or run rvm system to get back to the system ruby), was to remove all my gems:
gem list | cut -d" " -f1 | xargs gem uninstall -aIx
WARNING: this will uninstall all ruby gems. If you installed as root you may want to switch to root and run this.
2. Install new hotness
Now you can run gem list to see what is left.
Time to install rvm, I recomend blowing away your current install and reinstall fresh:
rm -rf $HOME/.rvm
bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )
Now the real trick is to use gemsets to install rails 3, and this is easy if you follow Waynee Seguin's gist:
rvm update --head
rvm install 1.8.7
rvm --create use 1.8.7#rails3
curl -L http://rvm.beginrescueend.com/gemsets/rails3b3.gems -o rails3b3.gems
rvm gemset import rails3b3.gems
One difference is I use 1.8.7 since I have had issues with 1.9.2-head and RSpec, but 1.8.7 has been smooth.
You say that you already got Rails 2 and afterwards installed rvm. Try if you can remove Ruby and Rails using the package manager of your system (yum, apt, ...)
The error you got is most likely the result a link in some general place which still exists, but is pointing to the real installation directory which no longer exists.
For example: /usr/bin/ruby exists and is pointing to /usr/local/lib/ruby/1.9.2/bin/ruby which no longer exists.
Afterwards manually clean out any Ruby and Rails related paths in /usr and its subdirectories.
