I have an ubuntu machine and I am trying to install rubygems using RVM by following this guide:
https://www.digitalocean.com/community/tutorials/how-to-install-ruby-on-rails-on-ubuntu-12-04-lts-precise-pangolin-with-rvm
When I run the command rvm rubygems current or even the command rvm rubygems latest I get the following error:
fl4m3ph03n1x: ~ $ rvm rubygems current
system - #downloading rubygems-2.4.8
system - #extracting rubygems-2.4.8.....

$LANG was empty, setting up LANG=en_US.utf8, if it fails again try setting LANG to something sane and try again.

At first I thought the error was due to the --no-document flag, but after reading and trying this discussion on github, nothing changed.
I also checked this stackoverflow discussion but it doesn't seem to be applicable to my case because I have a fresh installation (no manually installed packages nor anything).
Over all I tried using commands like rvm get head and rvm stable but nothing seems to work.
What am I missing? Could this be a permission's problem somehow?
EDIT:
This is the result of rvm list:
rvm rubies
ruby-2.2.1 [ x86_64 ]
# Default ruby not set. Try 'rvm alias create default <ruby>'.
# => - current
# =* - current && default
# * - default
I had ruby installed, but turns out it was not set in rvm.
To fix this first I tried using rvm use ruby --default, but I got the infamous "rvm is not a function" error.
To fix this, first run bash --login and then then rvm use ruby --default.
Once these steps are complete you can proceed with rubygems installation.
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
I just downloaded an app code from github and when I am trying to run the command rails s, I am getting this error -
The program 'rails' can be found in the following packages:
* rails
* ruby-railties-3.2
This is specific to this app only, can someone tell me how to fix this ? I am using RVM
In case anyone else has this problem, but the above doesn't work. Try running:
/bin/bash --login
then run
rvm use 2.0.0 #or whatever your version number is...
Not really sure what exactly your problem is. If you use rvm and have installed Rails with it, you may have to use
rvm use 1.9.3
(version number may depend on your installation). Then you may or may have not a gemset with this. So:
bundle install
should install Rails gem in this gemset. Maybe use
rvmsudo bundle install
or just manually install the Rails gem. But this would partially depend on the Rails version expected by the app. There are other options, but this should mostly work.
For setting a version permanently you can use:
rvm use 1.9.3 --default
For this to work you must have something like this:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
in your ~/.bash_profile.
In addition you can have something like a .rvm folder in your project where you can set rvm options on a project level if you need to switch between versins often (didn't use this myself, but there should be docs on the rvm homepage)
I have use /bin/bash --login for my ubuntu on raspberry pi after getting the same error. It's working right now.
I'm getting this error when I try to invoke rails, rails -v or rails -c:
/usr/lib/ruby/site_ruby/1.8/rubygems.rb:779:in `report_activate_error': Could not find RubyGem rails (>= 0) (Gem::LoadError)

I installed RVM, used it to install Ruby 1.9.3, and switched to it rvm use 1.9.3 --default.
When I ruby -v:

So somewhere something has a path that says to look at the system Ruby install. Any ideas? Thanks!
EDIT
Okay, also, If i switch back to the system Ruby, rvm use system, and rails -v, I get:
Rails 2.3.8
So I have no idea at all what this error is indicating.
You have not completed rvm installation. You need add ~/.rvm bin paths before /usr/bin by command in .bashrc:
[[ -s "/Users/pftg/.rvm/scripts/rvm" ]] && source "/Users/pftg/.rvm/scripts/rvm".
To test just check $PATH env. Should be similar to:
/.../.rvm/gems/ruby-1.9.3-p125#global/bin:/.../.rvm/rubies/ruby-1.9.3-p125/bin:/.../.rvm/bin:/usr/local/bin
If you installed everything ruby as well as rails means, you may need to select the 'Run command as login shell' checkbox by doing following,
Open terminal
Go to Edit tab, then select Profile Preferences from the menu item.
The Profile Preferences window should be displayed, then select Title and Command tab.
Then select the checkbox Run command as a login shell.
I just used RVM to create a "gemset", switched to it, and tried installing Rails again and it works now.
https://rvm.io/gemsets/
I'm not sure why that fixed it or why it wasn't working before. I like when things work, but I would rather have figured out why it wasn't working with the #global gemset.
Thanks for all your help!
I had the exact symptoms described above as well and was stuck on this problem for quite some time (the ruby environment and dependencies are a horrible mess). I can't say I'm out of the woods yet but at least I'm picking up the correct version of rails now and gotten past this error.
I believe the real issue here is actually to do with zlib. It seems that it's a crucial component to separate your system version of ruby (v1.8 likely install via yum/apt-get) with the other versions or Ruby you need (installed via rvm) for other projects.
If you do not have zlib installed, or rvm is not using it correctly, then sometimes you will pick up the system ruby/rails and all sorts of strange errors occur.
If you DO have zlib installed (yum/apt-get install zlib) then the trick I discovered was that I specifically had to tell rvm which version of zlib to use when installing ruby.
rvm install 1.9.3 --with-zlib-dir=$rvm_path/usr
I use rvm to manage different rubies and their gemsets. My shell is zsh with oh-my-zsh configured with basic settings. Enabled oh-my-zsh plugins are ruby, rails, osx, and git. Here's the command I used to install ruby-1.8.7 and rails-3.0.7.
rvm install 1.8.7
rvm use 1.8.7
gem install rails -v=3.0.7
and then I typed rails and got:
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.
I've tried more thorough installs also, Like reinstall rubygems after switching to ruby-1.8.7, or create a completely new gemset, but with no luck.
Here's the rvm info:

If you're running a rails command immediately after installing rails, you will need to restart your terminal before your commands will be recognized.
I had this problem today. Not completely related to your question, but since this page is what comes up in Google when I search for "Rails is not currently installed on this system", I thought I would add my answer:
What happened is that I was using ruby 1.9.2 with rails for a while, but then I needed to use ruby 1.8.7 to run some other script that I found.
Afterwards, I wanted to change by system back to using 1.9.2, and that's where the problem started:
$ rvm list
=> ruby-1.8.7-p352 [ x86_64 ]
ruby-1.9.2-p290 [ x86_64 ]
$ rvm use 1.9.2
I thought that would do the trick. But no, that gives me the "Rails is not currently installed on this system" message.
What I had forgotten is that I had configured rails using an rvm gemset. So I needed to specify the correct gemset when I was selecting which ruby version to make active.
$ rvm gemset list_all
gemsets for ruby-1.8.7-p352 (found in /Users/asgeo1/.rvm/gems/ruby-1.8.7-p352)
global
gemsets for ruby-1.9.2-p290 (found in /Users/asgeo1/.rvm/gems/ruby-1.9.2-p290)
global
rails31
$ rvm use ruby-1.9.2-p290#rails31
That did the trick.
Mac OS X, rbenv, and rails
I was getting the exact same issue but with rbenv rather than rvm. After verifying a correct .bash_profile.
.bash_profile
export PATH="$HOME/.rbenv/bin:/usr/local/bin:$PATH"
eval "$(rbenv init -)"
Restart the shell
exec $SHELL -l
Check the path
echo $PATH
Finally
I repeatedly installed and uninstalled rails but it was never placed in the .rbenv/bin directory after rbenv rehash. In the end I did a find . -name rails and uninstalled every gem that was returned and uninstalled rails. Then:
$ gem install rails
$ rbenv rehash
$ which rails
/Users/palmerc/.rbenv/shims/rails
I had the same issue and found that RVM was not showing as installed either if I tried the rvm command. All it took to fix both problems was running this command in the terminal
$ source ~/.rvm/scripts/rvm
Restart your terminal and then re-run your rails command
Rails is not reporting that it isn't installed. Your Debian system is telling you that rails isn't installed. One thing about rvm is that it relies on some complicated bash shell scripting and you sometimes need to start a fresh shell for changes to appear. You should also make sure that the correct rvm shell commands were added to your .zshrc file.
Also check your path to make sure the ~/.rvm/gems/... path in included.
I ran into this issue using rbenv. Turns out gem install rails did in fact install Rails but rails was not recognized as an executable. The fix for me was to run rbenv rehash.
I found this fix and more details on setting up Rails 5 at https://gorails.com/setup/osx/10.11-el-capitan
I have encountered this problem, but it has been resolved.
I use macOS, I do not use rvm, I only use HomeBrew, I first use gem env to get the installation directory of all gems, mine is:
$ gem env
RubyGems Environment:
-RUBYGEMS VERSION: 3.1.2
-RUBY VERSION: 2.7.1 (2020-03-31 patchlevel 83) [x86_64-darwin19]
-INSTALLATION DIRECTORY: /usr/local/lib/ruby/gems/2.7.0
-USER INSTALLATION DIRECTORY: /Users/myname/.gem/ruby/2.7.0
...
Then you try to go to /usr/local/lib/ruby/gems/2.7.0 to find the executable file directory of the rails gem that you have installed, for example: /usr/local/lib/ruby/gems/2.7.0/bin, then add to the path environment variable
I found this problem but the solutions above didn't solve it. I am not using rvm (and I'm working on mac) and I had to update the path to add rails executable directory:
echo 'export PATH="/usr/local/lib/ruby/gems/3.0.0/bin:$PATH"' >> ~/.zshrc
I had a similar issue, but with rbenv.
I originally installed ruby on bash. Then I played around with .bashrc in VIM, messed that file up, and reset it back to default. In doing so, I unknowingly removed the exported rbenv $PATH. Because of this, my terminal no longer recognized that I had ruby installed.
I revisited the ruby installation page (https://gorails.com/setup/ubuntu/15.04) and tried to set up my rbenv path again with this command:
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
It failed.
Luckily, I had already switched to zsh (with oh-my-zsh) between the time I messed up my .bashrc and the time I tried to access irb from my terminal.
My solution was to set up the rbenv path per the installation guide, but by replacing all instances of .bashrc with .zshrc like so:
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.zshrc
Hope this helps!
Here's what I've done. And the problem is gone. Hence I guess problem solved.
rvm use system
change to the system ruby. remove all gems in it using the command provided and explained here. then I install wanted ruby versions from scratch:
rvm install 1.8.7
rvm install rails -v 3.0.7
then bundle install
for further detail, might need dig into the gem install procedure.
add source ~/.rvm/scripts/rvm to your .bashrc file if rails installs fine but then you get the error "rails is not currently installed". This frustrated me for a while but I found the answer here: http://www.codelearn.org/blog/how-to-install-ruby-rails-screencasts-linux-mac-windows
I just reloaded my terminal
source ~/.bashrc
See: How do I reload .bashrc without logging out and back in?
Rbenv users
I had the same issue and this worked for me.
Setting the ruby version in the current directory.
rbenv local 2.7.1
Then I was able to run rails new
I had the same problem but the solution above didn't help.
This was my scenario
rvm list
=> ree-1.8.7-2012.02 [ i686 ]
ruby-1.9.3-p125 [ x86_64 ]
which ruby
/Users/dev/.rvm/rubies/ree-1.8.7-2012.02/bin/ruby
which rails
/usr/bin/rails
gem list --local
..
rails (3.2.8)
rails2_asset_pipeline (0.1.20)
railties (3.2.8)
..
rvm use ruby-1.9.3-p125
which ruby
/Users/dev/.rvm/rubies/ruby-1.9.3-p125/bin/ruby
which rails
/Users/dev/.rvm/gems/ruby-1.9.3-p125/bin/rails
By uninstalling rails and railties and reinstalling rails when using ree my problem was resolved.
Hope this helps others in my situation, not sure how I got into it :S
I had the same problem, I ended up deleting my .rvmrc rvm --create --rvmrc 1.8.7#project where the 1.8.7#project is whatever you want your ruby to be. cded in and out and it worked. http://sirupsen.com/get-started-right-with-rvm/
Just had same problem and couldn't find an answer. Here's what I did:
find current rails path
$ which rails
returns something like this: /usr/local/rails
Delete current version:
$ sudo rm -rf /usr/local/rails
Reinstall rails
$ sudo gem install rails
I ran into this same issue and none of the answers given helped so I thought I'd share my solution in case it might be useful for someone else.
I was messing around with my .profile and .bashrc files and along the way I messed up my RVM install. Still not sure exactly what I did, but the fix was easy. Just had to run the following command, which cleans up all of your system path settings for RVM:
rvm get [head|stable] --auto-dotfiles
Note that if you're running an old version of RVM this may upgrade your setup, which may not be what you want.
A possible solution is to not maintain two different configuration files .bash_profile and .bashrc
The solution as suggested in this excellent post on the difference between .bash_profile and .bashrc is to source .bashrc from your .bash_profile file, then putting PATH and common settings in .bashrc.
Quoting,
add the following lines to .bash_profile:
if [ -f ~/.bashrc ]; then
source ~/.bashrc
fi
end quote
I had this error after updating ruby. I had to run 'bundle install' to fix it.
Try to specify gemset explicitely in your Gemfile:
source 'https://rubygems.org'
ruby "2.2.3"
#ruby-gemset=rails424
Try This:
You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use /bin/bash --login as the command.
$ bin/bash --login
$ rails -v
I had this message on my Mac:
Rails is not currently installed on this system. To get the latest
version, simply type:
and it was about the $PATH not being correct. The system has an outdated version of rails (/usr/bin/ruby). The path to your chosen version of ruby ($HOME/.rbenv/versions/2.3.0/bin) must precede the system's outdated version along $PATH var, like below:
export PATH="$HOME/.rbenv/versions/2.3.0/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:$PATH"
adjust it to your version of ruby.
For MacOS (High Sierra):
Tokaido is the Rails installer system recommended on the "Getting Started" Rails guide page for Mac OS. But it doesn't just install, it runs its own shell scripts. If you start out using that, which sources its own shell environment, then later start a terminal without launching from the Tokaido shell, this happens, because the "rails" command falls back to the original system rails code on the Mac.
For mine, the 'which rails' command in a normal terminal returns
/usr/bin/rails
But after launching Tokaido's shell, 'which rails' gives this path:
/Users/charlesross/.tokaido/Gems/2.2.0/bin/rails
Out of nowhere Rails wasn't currently installed but, what fixed it was
rvm use ruby-2.6.0
...and verified my path in .bash_profile
export PATH="$PATH:$HOME/.rvm/bin"
I was having this problem today. I haven't 100% solved it, but in new tabs I can do rvm use 2.5.5 and then rails -v works fine.

I was looking through the source and found another error message that suggested the user run the following command.
I ran the command and everything now works. None of the suggestions above worked for me. Run the command from inside your newly created Rails app.
gem pristine --all
Here is how it worked for me:
Intall rvm in mac by following the mac installation instruction
rvm install ruby
gem install rails
rails --version
For me ( MacOS Monterey, rbenv) adding rails version to gem install command get the problem resolved.
you can find a specific version of rails that matches to your ruby from this link and replace the VERSION .
gem install rails -v VERSION
rbenv rehash
after successful installation, then rails should be added to /Users/your_user/.rbenv/shims
Also plz check that your shims directory should be the first element of your path.
