My RubyGems isn't working, throwing an error which goes as follows, triggering (nearly) on any Gem task:
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems.rb:1081:in `<top (required)>': uninitialized constant Gem::GEM_PRELUDE_SUCKAGE (NameError)
from <internal:gem_prelude>:1:in `require'
from <internal:gem_prelude>:1:in `<compiled>'
I'm new to Ruby / RubyGems / installing Ruby and all I know is that an uninitialized constant is essentially a undefined variable. It could also be possible that it's something with Ruby itself, although the ->Gem:GEM<-_PRELUDE_SUCKAGE points me to RubyGems.
In a nutshell, I installed a bunch of Ruby things (think RVM, rbenv, etc.) to develop Ruby on Rails, as I thought it would be a good way to learn Ruby.
Well, after going through a long and tedious process to upgrade Ruby to 2.6.3, then downgrade to 2.5.5 and then 2.4.0, then back up to 2.5.5 and solving downgrade issues, RubyGems throws the error. I settled on 2.5.5 because 2.6.3 caused errors and 2.4.0 was too early of a version.
It's causing all sorts of errors, like HAML not compiling and Rails not making a controller. I really don't know what's happening.
If I run gem install [gem name], it throws the error. Running rails generate controller [name] index (for those not familiar to Rails this creates, well, a controller) it throws the error. Doing anything really with the gem command causes the error, except for gem server.
If I upgrade back up to the latest Ruby version, I fear that my gem command will go all wonky again and I'll have to go through another day of troubleshooting versions. How do I fix this, or at least get rid of the message so I can create things again?
I had this happen to me just today. It seems, somehow, my ruby version had been corrupted. When I ran rvm list version 2.5.1 was listed as 'broken'. I had to uninstall 2.5.1 fully (using sudo even in my case) to get to a clean slate.
Then, when attempting to reinstall, rvm was giving me all kinds of grief after a new gpg key which I initialy couldn't get to install properly (hint).
After a clean wipe of ruby 2.5.1, updating rvm to latest version and reinstalling, I got this error: Error running 'env GEM_HOME=/ruby-2.5.1#global GEM_PATH= /Users/user/.rvm/rubies/ruby-2.5.1/bin/ruby -d /Users/user/.rvm/src/rubygems-3.0.8/setup.rb --no-document',.
It appears that an update to MacOSX deprecated a version of OpenSSL which causes some issues. I ended up following this thread and ran rvm gemset create global --default and then bundle install to get passed the Gem errors.
Honestly, rails is supposed to be easier than this. I wish docker was easier to reason about sometimes. These are the kinds of issues docker supposedly promises to fix eh?

I have tried this a number of different ways. First I tried with RVM and it was just error after error and missing dependencies. Then I tried Rbenv and it was very much the same.
Now, I have a combo of chruby and ruby-install to handle my versions of Ruby, but I can't update Bundler.
It says that I am currently on 1.17.2, but I need 1.17.3.
How do I upgrade this? I have searched everywhere, but all the solutions seems to be for RVM.
When I try to update Bundler this is the error that I get:
$ gem update bundler
ERROR: Loading command: update (LoadError)
cannot load such file -- zlib
ERROR: While executing gem ... (NoMethodError)
undefined method `invoke_with_build_args' for nil:NilClass
I don't know what is causing this or how to get around it. Any help would be appreciated as I can't seem to find anything describing what is happening.
So, it turns out that I had multiple versions of Bundler installed on my machine and, somehow, two of them were simultaneously set to the default version.
Manually finding the installed versions, deleting them and then reinstalling the desired version seemed to fix the issue.
The key is using a Ruby manager (RVM, rbenv, etc.) and ensuring that any installation of a Ruby version and/or gems are done at either a system level or inside of a project as required.
I was happily using Emacs's evernote-mode until stupidly removed OS X system ruby (I'm on Yosemite). Then I tried installing one via RVM (first tried 2.0 then 1.9), got all necessary gems, yet thing is still broken. Throws this message:
$HOME/.rvm/rubies/ruby-1.9.3-p551/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- oauth (LoadError)
from $HOME/.rvm/rubies/ruby-1.9.3-p551/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:54:in `require'
from $HOME/.rvm/rubies/ruby-1.9.3-p551/bin/enclient.rb:40:in `<main>'
Please help me to fix that
upd: I don't see the point of reinstalling system ruby (as people suggested) and then having it conflicting with those that I want to use via RVM. Ruby developers advise to use RVM. I symlinked my default Ruby to /usr/bin/ruby.
I seems that specific script uses something I don't have. I remember having hard time figuring out all dependencies and gems and installing them the first time I used that script and after hours of investigating it finally worked. But this time I got stuck.
I tried to run the script outside of Emacs and it runs with no errors (maybe that's not enough to find what's broken)
I tried to run irb and require modules one by one. It says => true until reaches require 'oauth/consumer'. I guess that's what's missing maybe? I run gem install oauth_consumer. It installed few gems, and now says => true for oauth/consumer in irb, the script though still doesn't work
i removed systems ruby once. i just had to go to the trash and put back everything i deleted and it worked for me. don't know how you "removed" your system ruby. besides, if you installed one with RVM then you have to tell RVM to choose and use/set a default ruby. because RVM won't install ruby 1.9.1 (rather a higher version which i think you did). So you have to set to that version.
Like this:
$ rvm --default use 2.1.5
don't forget to install oauth as well. Hope it helps.
I'm attempting to build local Ruby documentation as suggested here:
https://github.com/toy/doc
However when I use the default Rakefile I get the following:
[Documentation]$ rake build
configuring and updating: 100.0%
rake aborted!
undefined method `available?' for Gem:Module
/Users/snowcrash/.rvm/gems/ruby-2.0.0-p195/gems/sdoc-0.2.20/lib/sdoc/json_backend.rb:9:in `<top (required)>'
Any suggestions?
I don't know much about ruby (and even less about the gem ecosystem built up around it), but I believe a possible workaround for this issue is to find what gems the project requires and manually install them. In the case of this particular project, it looks like you need the gem "fspath".
At the project root, type
gem install fspath
and try re-running rake.
I honestly don't know the actual root cause of the issue, other than that presumably, your version of the 'gem' program is probably > v2, while some other program (rake?) expects it to be older and still support the "available?" method.
If installing "fspath" doesn't fix the issue, you could try downgrading your version of gem by doing
gem install -v [some version of gem older than v2]
Check gem install --help for more info on this.
This is just for future visitor who has the same issue.
As ekremkaraca said, you can just solve this by downgrading rubygems.
rvm install --force rubygems 1.4.2
I'm trying to start a rails application in IntelliJ with the Ruby plugin.
I've imported the application and set up the run configuration as best I can. When I try to run it I get the error:
NoMethodError: undefined method `version_requirements' for #<Gem::Dependency:0x7de21f45>
When looking for an answer I found this page saying that I should do this:
$ gem install rubygems-update -v='1.4.2'
$ gem uninstall rubygems-update -v='1.5.0'
$ update_rubygems
Since it's IntelliJ's ruby plugin that is managing the gems, I assume that I have to change the version of rubygems-update that the plugin is using.
Is this the right approach to take? And if so, can anyone tell me how to go about it?
I tried listing the gems but that gem is not shows so I must not be listing the gems in the right place, but I don't know where to look.
Many thanks :)
IntelliJ IDEA cannot handle it, you will need to install the appropriate rubygems version from the command line.
Note that your current rubygems-update version may be different, verify it with gem list and use the reported version when uninstalling.
I have been trying to install sinatra in a macbook running leopard system, and I am not able to do it.
I get the following error.
MacBook:rubygems-1.3.7 lakshmanan$ gem install sinatra

Please help. I reinstalled gems also. Still I get the same error.
rubygems.org does not seem to be responding right now. Try again later. It's probably nothing on your end.
