I was trying to install Sinatra and I kept on getting this error: You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory
Thanks to "Installing gem or updating RubyGems fails with permissions error" I installed rbenv. I followed the guide and set my global ruby version, etc. but I continue to get the same error when I try to install gems. When I run gem environment the installation directory for RubyGems is still the system Ruby directory.
Should I update GEM_PATH? Since the rbenv guide doesn't mention anything about that, something makes me think that there is still a problem with my rbenv installation.
Can someone please help me figure this out?
You're not showing us the commands you're using but it smells like you're using sudo to install Sinatra. Don't do that with rbenv or RVM managed Rubies.
Just as in the linked question, using rbenv or RVM allows you have one or more Rubies in your user-space where you can modify them all you want. That means you don't need to use sudo, just use gem install ....
An alternate problem you could be having is you set your global Ruby to be system, which is the version installed by Apple for their use, and which you don't want to modify unless you understand why it's there and what they're using it for. IF you have to change it then sudo would be appropriate but, with rbenv or RVM managing Rubies in your user-space there's really no reason to.
Do NOT use chmod to change the ownership of the vendor installed gems; Again, that's for Apple's use so have fun with the local Rubies instead and leave Apple's alone.
In this case, I quit Terminal and upon reopening, things were working correctly. Probably a good thing to try if you're stuck and are sure you've followed instructions correctly. It's not explicitly mentioned in the material I read but I believe is a good practice in general.

I've been using Middleman since a while, but very recently it is getting some issues in loading.
This is likely due to the coexistence of very old gems of the same type.
Have to say that I did follow some online suggestions, but haven't really got the full understanding. So ended up using rbenv for managing ruby then bundle to install the gems.
Now, have two project that for which I need to "reset" and install only the referenced gems into the local folder or somehow they don't conflict.
I can't figure out how to do it.
Using the rbenv -local I can change the local ruby version, but not sure how to move next.
Any help?
Thanks
I don't think you need rbenv or rvm for this, although their are good tools. To run a piece of code with just the gems you need, and the versions you specified in your Gemfile, run any command prefixed with bundle exec.
For example bundle exec middleman server.
I am using overcommit gem (https://github.com/brigade/overcommit) in my project, when I use Github Desktop for osx I get these errors:
This repository contains hooks installed by Overcommit, but the
overcommit gem is not installed. Install it with gem install
overcommit. (1)
The gem is installed, it works in terminal. I guess it's because I use rvm and Github Desktop doesn't know about rvm. Anybody knows how to fix this?
Ok finally got it to work!
Combined the answer from #michelegera with comment from #rewritten
Step 1:
sudo su -
gem install bundler
gem install overcommit
gem install rubocop
Step 2: added command: ['bundle', 'exec', 'rubocop'] to .overcommit.yml
Thanks for the help!
Most likely it's this line where the error occurs. As you can see the main issue is that it's not able to require 'overcommit'. I don't know the GitHub desktop client so well (maybe there is a way to configure it inside of it), but one thing you could do is adding the absolute path where rvm stores your gems to the "require path" in the hook file. This could look like:
$: << "/home/user/.rvm/path/to/gems/dir"
The disadvantage of this is that you would have your absolute path in the hook file and it most likely won't work for others. You might also want to consider installing the gem globally for the the ruby interpreter that executes the script (see Shebang line in the hook file).
You are right, Github Desktop (or any other GUI) isn’t running in your terminal environment, so it knows nothing about your specific RVM installation.
A simple solution is to install overcommit and any other gems required by your hooks into your system Ruby:
sudo su -
gem install bundler
gem install overcommit
gem install rubocop
...
If you installed Git via Homebrew or other means, you might have to change the Git binary used by your GUI.
For example, in Tower, I selected Homebrew’s version rather than the System’s.
I'm pretty sure I know where my gems are being installed to, but I can't call them. I'm thinking this might be an issue where the gem program is not looking in the right directory for the gems. Can somebody help me figure this out?
EDIT On linux
The very first thing to do when running into gem issues is enter:
gem env
This will tell you everything that Ruby knows about your Rubygems environment.
If you are running RVM then enter:
rvm info
If you are on linux you can set GEM_PATH in your bash_profile or bashrc (or zshrc, if you're using zsh) files. I'm not sure about OSX.
turns out the gem i was trying to install was broken. lesson is dont rely on tutorials thAT may nbe out of date to help you install gems
i originally followed these steps to get a RoR environmentgoing: https://help.ubuntu.com/community/RubyOnRails
that worked. then i put 1.9.2 on here. then i decided i want the original setup, did a "whereis ruby" and deleted those directories manually.
that fubar'd my ruby installation. i can't use the repository to what i originally had. how can i purge ruby from completely and start fresh?
right now the specific error is this:
/usr/lib/ruby/1.8/rubygems.rb:11:in `require': no such file to load -- thread (LoadError)
from /usr/lib/ruby/1.8/rubygems.rb:11
from /usr/bin/gem1.8:8:in `require'
from /usr/bin/gem1.8:8
tipu#tipu_ubuntu:~$
You're not giving enough real information to be specific, but this is what I'd try:
Use apt-search to locate Ruby 1.8.7 for your OS version.
Using apt-get, uninstall that version so you're back to what APT thinks is a clean slate.
Again using apt-get, reinstall that version so you're back to what APT thinks is a normal installation.
From that point, I would STOP messing with the system Ruby, and instead use RVM to manage and install any new Ruby and gems installations into RVM's ~/.rvm sandbox.
To follow up on the Tin Man's answer:
I wrote a guide to installing Ruby and Rails on Ubuntu which you may find useful for getting this all peachy again.
Hope it helps!
You need to reinstall libruby1.8. I'm pretty sure that will take care of it. I had exactly the same problem.
After a recent reinstallation of Ubuntu, I reinstalled RubyGems. The Ubuntu repository grabbed version 1.3.5. Later I found I need the latest version. So I installed the RubyGems update to get to version 1.3.7.
The trouble is, upon upgrading gem list returns only a small subset of all my originally installed gems. In the past, I've solved this by reinstalling all my gems following an upgrade, but this is troublesome and I hope to avoid this workaround now and in the future.
I tried adding an export GEM_HOME to my .bashrc file. It didn't work. gem list still doesn't list all my gems (even though I can find them on my computer in /var/lib/gems/1.8/gems. I also created a .gemrc yaml file and set the gemhome path. When I run gem env I can see that the home path is set, but still gem list doesn't return everything.
What's up with this?
This won't directly answer your question, but a lot of us use rvm to manage Ruby and gems. The benefit is it doesn't require us to mess with the system's Ruby installation and gems, leaving those alone for any OS routines needing a particular version of Ruby or a gem.
Since switching to rvm I've quit installing an updated version in /usr/bin/local too as rvm makes it so easy to keep my development versions separate from the system.
There are great reasons to tweak the system gems so I won't question why you might do so. I'm just tossing out the rvm thang as it might help solve your needs.
