I'm using ubuntu, zshrc, and after installing rails, using
gem rvm all do gem install rails
and getting a successful install, i'm getting a
zsh: command not found: rails
I'm guessing this has to do with my ~/.zshrc file
I have this at the end of it:
export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
export PATH=$PATH:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
I'm a noob at understanding how paths work, any idea how to get terminal to recognize rails commands?

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:

I also gem install rails --no-rdoc --no-ri and checked...ls ~/ruby/gems/gems/:

And if I echo $GEM_PATH:

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 just recently switched over to using zsh with oh-my-zsh and I am having issues using the rails command line tool. Here are the steps that I ran through, and the error that I am receiving.
I ran the curl command that the github page provides:
curl -L https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh | sh
Then I went to run rails s, this is the following error message that I receive:
.rvm/rubies/ruby-1.9.3-p0/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find railties (>= 0) amongst [bigdecimal-1.1.0, io-console-0.3, json-1.5.4, minitest-2.5.1, rake-0.9.2.2, rdoc-3.9.4] (Gem::LoadError)
This looks like I am having a gem error so I reinstalled rvm, rails and bundler with nothing solving the issue. However if I switch my terminal back over to bash then I dont have any issues and rails works perfectly fine. Has anyone else run into a similar issue? I want to use zsh because it seems like it has better features but if I can't use rails then I have to dump it to the curb.
These are the lines at the end of my .zshrc file:
export PATH=/Users/thomascioppettini/.rvm/gems/ruby-1.9.3p0/bin:/Users/thomascioppettini/.rvm/gems/ruby-1.9.3-p0#global/bin:/Users/thomascioppettini/.rvm/rubies/ruby-1.9.3-p0/bin:/Users/thomascioppettini/.rvm/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/usr/X11/bin
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
What I have done to work bundle zsh and rvm, that is couple of body movies:
1) add to .zshrc at first line to correct find bin direcrory (your CO):
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
2) add next line after previous one:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
3) and at the end change PATH:
export PATH=$PATH:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
For me it is work fine (now it correct define $PATH with all rvm gemsets)
did you put the
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
into your .zshrc?
I assume the rvm-installer installs it only into .bashrc
Ok I got it to work by deleting the path that was set in the zshrc and copying the rvm lines from my bash_profile in order to get the right configuration from rvm. If you run the following command in your terminal it should work:
cat ~/.bash_profile >> ~/.zshrc
If you are using rbenv then copy this line from bash.rc which you can access by sudo gedit ~/.bashrc
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/bin:$PATH"enter code here
eval "$(rbenv init -)"
then paste it to zshrc, which can be accessed by sudo gedit ~/.zshrc
I am using ruby on rails on Ubuntu 11.10. Ruby 1.8.7 works fine but I cannot get rvm to work with 1.9.3 or any other version.
When I run rvm reload, rvm list or rvm info, I get the following message:
bash: /usr/bin/rvm: No such file or directory
I have Ruby 1.9.3 installed via rvm and when I change the default it doesn't give me an error. But then when I check the ruby -v it defaults back to 1.8.7.
Also, when I check which ruby it shows the following:
/usr/local/bin/ruby
My guess is that it has something to do with the bash file. What do you suggest?
I am guessing that it isn't even installing it correctly.
This is what happens:
I type the following into the prompt:
bash < <(curl -sk https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
And it outputs:
ERROR: Unable to checkout branch .
Are you following the installation instructions from the rvm site?
http://beginrescueend.com/rvm/install/
If you are then look at section 2 about the shell again.
specifically this command that they tell you to run :-)
echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile
remember to reload or restart your shell after running that command.
run the command
source /usr/local/rvm/scripts/rvm
and then
type rvm | head -1
you should get output -
rvm is a function.
And after that run
rvm use rvm use 2.0.0 --default
I have installed ruby via rvm on Mint 11 no problem. Installed gems, ditto. Installed rails via gem install rails, and when I type rails -v it returns the correct version. Until I close that terminal and reopen a terminal. When I do that and type rails -v I get the message
The program 'rails' is currently not installed. You can install it by typing: sudo apt-get install rails
If I then type
rvm use 1.9.2-p180 --default
and then type rails -v I again get the correct version...until I close the terminal.
I should add that I have added a path statement to my .bashrc pointing to the 1.9.2-p180 directory in my .rvm directory.
Typing ruby -v always returns the correct version.
Create .bashrc file and add .rvm command
$ sudo touch ~/.bashrc
$ sudo gedit ~/.bashrc
(Add line to .bashrc file)
if [[ -s "$HOME/.rvm/scripts/rvm" ]] ; then source "$HOME/.rvm/scripts/rvm" ; fi
Logout and Login OR just update user profile from .bashrc with following command
$ . ~/.bashrc
Try adding this command to your .profile and reopening your shell:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
Use project rvmrc files. You can see how to set this up here http://beginrescueend.com/rvm/best-practices/
That way you keep all your gems seperate for each project and it's dead simple to set up
Try which rails. Maybe there is a link to a stub that gives you the note.
If that is the case calling the full path might help, e.g. /usr/local/bin/rails
I'm trying to get rails setup up on a mac following this tutorial and a tutorial on rubysource.com
I have installed oh-my-zsh and RVM but when I try the command:
rvm type | head -1
I get zsh: correct 'rvm' to 'rvim' [nyae]?
Which is throwing me because this should display in the terminal:
rvm is a function
If I choose 'n' I get:
zsh: command not found: rvm
and if I choose 'y' I get:
Vim: Warning: Output is not to a terminal
I'm super new to using a mac (bought it yesterday) and am struggling with getting ruby and rails all set up as I do on my windows system.
Any help is much appreciated!
You have probably forgotten to add the line to your .zshrc which loads RVM.
As given at your first link:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
If this line is in ~/.zshrc, then RVM should be loaded when you open a new shell. Otherwise, you'd have to run
source ~/.rvm/scripts/rvm
Whenever you wanted to use RVM.
