I'm on Mac OSX Snow Leopard. I tried to post a similar question to the RVM Google group but it did not seem to get posted.
I'm worried that I've done something fundamentally wrong with my RVM install that's causing these errors, that seems to be related to paths, at each step of the way. Have any of you seen this behavior before?
I started to teach myself Rails programming as of about two months ago with a working environment of Ruby 1.9.1 and Rails 3.0.3, based on a hivelogic install tutorial that had me modify my ~/.profile file and install the relevant bits to ~/usr/local/src/. For reference, the line in my ~/.profile file was this when I installed RVM, if that makes any difference:
export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/local/src:$PATH"
In my terminal I installed RVM as a user using the standard user github bash script.
I tried to install Ruby 1.9.2, which kept running into a weird error about a libfile somewhere. After much Googling I found someone on Stack Overflow that recommended renaming the ~/usr/local directory while performing the Ruby install -- I did this, and the install complete.
Then I did gem install rails and tried to do bundle install in my app, which gave an error when trying to install the SQLite3 gem (even though I already had SQLite3 installed and working). Again, I spent a day Googling this and eventually found "Unable to install sqlite3-ruby gem" that said if I used Macports to sudo port install sqlite3 it would work.
I tried that from the base directory, and Macports did its thing but it didn't fix the problem. Then I did the same thing from my app directory and it fixed the SQLite3 error I was getting.
Now I am able to run rails server and rails generate again, which is great, but then I tried to "annotate" my new model, and I get this error: http://pastie.org/1481570
I have not yet solved this issue, and have looked at many threads of similar issues. This, for example, did not solve my problem: https://github.com/james2m/annotate_models/commit/5997da9692c9b222e8d1be22dfad6ed8638c16a1
I even tried copying my source code directly into the rvm/user/ directory in case that relative path was causing problems, but it doesn't seem to have fixed anything. Maybe I need to uninstall RVM and re-install it as root instead of a user-level thing?
What do you think is the best way to get annotate to work and hopefully get RVM to play nice with my gems going forward?
I'm unfortunately REALLY new to terminal, code, etc, so any help would be much appreciated.
On Snow Leopard you should modify either ~/.bashrc or ~/.bash_profile, preferably the later. Also, RVM will not need anything in ~/usr/local since it's entirely self-contained in ~/.rvm.
RVM uses a nice little shell function to sense the needed directories and desired default Ruby. I suspect either the instructions you followed were very out of date, or poor recommendations. The current RVM installation requests you add:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
to your ~/.bash_profile
The RVM site has lots of troubleshooting tips for things like MySQL. I'd strongly recommend backing out of the things those other tutorials had you do, and refer to the instructions on RVM's site. It is very easy to get things working right if you do it the RVM-way.
Download and install Apple's latest version of XCode from their Developer site if you haven't already. There have been some broken versions shipped on the DVDs.
Install. In particular follow the "Post Installation" section.
Following that, do whatever rvm notes says to do as far as libraries. Following that, you should be able to use rvm info to gather useful info about your installation. It is your best friend.
Database integration will point you to how to fix MySQL's wagon.
RVM development happens fast. Keep it updated, at least once a week using rvm get head.
At that point you should be in a good place to start reinstalling gems.

I am new to RVM and looking to use it as I deploy my Rails app to a Digital Ocean server. I am following this tutorial and trying to get my Mina script to run (similar to Capistrano). The script includes a set up section with these lines:
source /etc/profile.d/rvm.sh
rvm use || exit 1
Unfortunately, rvm.sh does not exist in /etc/profile.d (or anywhere else on my server). rvm seems to be installed just fine (I can set list rubies, set my Ruby default version, etc). I'm not even sure what rvm.sh would contain if it existed.
Thanks in advance for any help or suggestions you can provide.
#mpapis got me on the right path here. I had installed rvm under one user, but not for this user. I wound up uninstalling rvm and starting from scratch, installing rvm for multiple users.
I am new to Ruby and coding in general, and am trying to do a set of problems. However, I am unable to even get to the problems because the files I will be using require Rbenv and Bundler, and I cannot seem to install them on my Mac.
Can someone please give me a really simple explanation on how to correctly download the files (git ?) and install them via my terminal?
I have gone to github and downloaded the rbenv-master folder and saved it in a folder on my desktop. (https://github.com/sstephenson/rbenv)
I can open my terminal and navigate to this folder.
Should I be saving something from the entire folder differently and loading that?
If so, what do I save it as and what do I type in my terminal to load it?
Once I do that, do I have to do anything else (use the require command??) to use this in my exercises?
Thanks for taking the time… I'll probably look back on this as a stupid questions. :)
You can just follow the homebrew install install instructions on the rbenv github page.
You just may need to install homebrew first if you don't have it. Which is a one-line command found on the homebrew homepage.
I upgraded my Mac to the new OSX 10.10.
brew update failed with:
/usr/local/bin/brew: /usr/local/Library/brew.rb: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad interpreter: No such file or directory
/usr/local/bin/brew: line 23: /usr/local/Library/brew.rb: Undefined error: 0
I tried to follow "Getting a "bad interpreter" error when using brew", but I couldn't get it working.
I do not have Ruby in /usr/local/bin or /user/bin, which may be for same reason which ruby returns nothing.
I have Xcode 5.1 with the command line tools installed. Whenever I start terminal I get:
-bash: /etc/profile.d/sm.sh: No such file or directory
-bash: /etc/profile.d/rvm.sh: No such file or directory
Can anyone suggest possible solutions?
First off upgrade Xcode to 6.1 This is the version that works with Yosemite.
After that make sure you RUN Xcode and Agree to the license ( i know it sucks ).
Note: After Updating My "Oh My Zsh" tools and restarting Xcode it installed some command line tools that I'm pretty sure are important.
There are things to note:
Mac OSX does come with a Ruby preinstalled in /bin/ruby. That is Apple's own installation, used for some of their tools, and basically should be ignored. Updating it could break those tools, and worse, deleting it, will break them. Trying to reinstall it is a pain, so it's better to pretend it isn't there.
We generally recommend using either RVM or rbenv to manage/install any other Ruby version. Those tools are well tested and make it easy to switch back and forth between versions.
rbenv is easier to manage but lacks some of the features of RVM.
Closely follow the RVM installation instructions if you go that way; We see a lot of questions on Stack Overflow caused by people who ignore the directions, or who follow directions on a different site besides RVM's home site. (The RVM authors really do know better than anyone else how to make it work.)
Brew can install Ruby, but switching between versions gets stickier.
It sounds like your PATH variable doesn't include /usr/bin, which is odd, because it should. If it did, it should find the default Ruby.
echo $PATH
will display your search path. It's editable and, if
ls /usr/bin/ruby
shows that Ruby does exist in /usr/bin then you should add it back into the path. You can do that by editing ~/.bashrc, but also check ~/.bash_profile to make sure something isn't messing up the path. And, if you don't understand how the path works, take the time to read about it, because a badly set-up PATH variable can slow your use of the command-line, or cause all sorts of weirdness.
By default there is no /usr/local/bin/ruby. It won't exist using RVM or rbenv either, but Homebrew will probably put a symlink; I don't have it supplying my Ruby, so I can't check that.
I'm a ruby and vim newbie. I recently installed the rails.vim plugin and all the commands work fine apart from the commands to create a new Rails project. Every time I do this it says rails is not installed on my system, but it is! It also acts up when I create a class that requires a gem that I've installed. Can anyone help with this?
Did you rvm use system before building / brew install-ing macvim? I didn't and got many errors. Doing rvm use system beforehand fixed things up for me.
I'm on a Mac running 10.6.4 Snow Leopard, and apparently ruby comes ready to go. But I'm new to Ruby, trying to learn the Rails framework, and so i decided to install the latest version 1.9.2. I followed the instructions here, but after I compile and install, when I run ruby -v I'm still getting 1.8.7. Anyone can help a noob out?
When I use which ruby I am getting usr/local/bin/ruby, so the path has changed and is correct.
UPDATE:
It seems I was having issues because I was using two login files to set my path (.bash_login and .profile). You can only use one, and the first one that exists and is readable will be used. I eventually switched to RVM and used .bash_login to load RVM into shell.
Well, the sw isn't lying to you. So something is not as you expect.
Try /usr/local/bin/ruby -v and see what version it is.
Added: Also, try locate ruby|more to see where the ruby files are on your system.
You may need to change your path to use your newly installed copy of ruby.
Added more: did you add the Path to your ~/.profile file as the instructions tell you to do in step 1?
Did you restart your terminal session after changing the ~/.profile file? (Quit and restart terminal.)
