Rubygems 2.0.14 is not threadsafe, so your gems must be installed one at a time. Upgrade to Rubygems 2.1.0 or higher to enable parallel gem installation.
I have tried bundle update as well as bundle install --without production

How do I upgrade Rubygems in Bluemix? I'm getting this message:
Rubygems 2.0.14.1 is not threadsafe, so your gems must be installed one at a time. Upgrade to Rubygems 2.1.0 or higher to enable parallel gem installation.
and since I have a lot of gems, I'd really like to use this feature.
I'm using Ruby buildpack version 1.6.7 and Ruby 2.0.0.
gem install rubygems-update
update_rubygems
# gem update --system # in fact, you are done on the previous step
Use gem update --system as stated here
Solved by using newer Ruby version 2.2.2 in newer buildpack.
I had rubygems 1.3.5 (or 1.3.6?) installed and then made a sudo gem update after a long while again. Some gems complained they needed a newer gems version. Because sudo gem update --system is deactivated on Ubuntu I followed these steps: How can I get RubyGems 1.3.6 on Ubuntu 10.4
But now I cannot start the dev_appserver.rb anymore, it says:
=> Bundling gems
ERROR: While executing gem ... (RuntimeError)
Unknown command bundle
I also tried to do sudo gem update and sudo gem update --system again a few times but everything is up-to-date now. Here is a list of my gems: http://pastebin.com/cFaTCyF5
It's a bit of a hack around but I can't really tell what's going on properly from what you sent but I know a few people have been having problems after running gem update --system lately. Find out what version you've just installed with
gem list
Look for the update, should look something like this: rubygems-update-1.5.0
Then try rolling back your rubygems version
sudo gem uninstall rubygems-update -v 1.5.0
sudo gem install rubygems-update -v 1.4.2 <-- try a different version
gem install --system 1.3.7 worked in my case
I tried to install hoe and I encounted this:
Installing hoe (2.9.1)
/Library/Ruby/Site/1.8/rubygems/installer.rb:170:in
`install': hoe requires RubyGems
version >= 1.4. Try 'gem update
--system' to update RubyGems itself. (Gem::InstallError)
I am now worried the update might corrupt my previous installed gems...
gem update --system will only update rubygems itself.
Previously installed gems are not affected and should run just like before.
Or is there a specific gem or situation you are worried about?
Upgrading RubyGems won't affect previously installed Gems.
Trying to install the 'less' gem. I type sudo gem install less as instructed at http://lesscss.org/, and I get the following error:
ERROR: While executing gem ... (Gem::GemNotFoundException)
Could not find less (> 0) in any repository
Alright, so I figure maybe I just need to update RubyGems. Trying 'gem update --system' gets me
Updating RubyGems...
Attempting remote update of rubygems-update
ERROR: While executing gem ... (Gem::InstallError)
rubygems-update requires builder >= 0
Arrgh. Alright, then let's try 'sudo gem install builder':
ERROR: While executing gem ... (Gem::GemNotFoundException)
Could not find builder (> 0) in any repository
Seems that no matter what gem I try to install, it can't be found in any repository. I check my environment, and rubyforge is listed:
RubyGems Environment:
- VERSION: 0.9.4 (0.9.4)
- INSTALLATION DIRECTORY: /usr/local/lib/ruby/gems/1.8
- GEM PATH:
- /usr/local/lib/ruby/gems/1.8
- REMOTE SOURCES:
- http://gems.rubyforge.org
Any idea what's going on? I'm on OSX 10.4, and I installed Ruby 1.8.6 before this.
I think rubygems 1.3.x requires ruby 1.8.7 so you might install that first. Then update rubygems to 1.3.7. via gem update --system
The version of rubygems bundled in osx uses gemforge as its offical source of gems - this has since been replaced with gemcutter. You should be able to do
sudo gem update --system
To upgrade to update the latest version of ruby gems, which will then use gemcutter as the sources link
That's a really old version of rubygems! How did you install this?
Is it a manual install? If so, perhaps you could try a manual upgrade the same way.
Do the following:
sudo gem update --system
to update your install of RubyGems. Then, add the Github gem repository to your sources. I suggest github because you'll find a lot of useful things there:
sudo gem sources -a http://gems.github.com
I can't update the rubygems from 1.3.1 to 1.3.5. I've tried the following commands with no luck(logged in as the root)
gem update --system
gem update rubygems
gem update rubygems -v 1.3.5
gem install rubygems-update -v 1.3.5
The response for the first three command is
Updating RubyGems
Nothing to update
while for the last one the response is
ERROR: could not find gem rubygems-update locally or in a repository
Also the current rubygem fails to install some required gems such as 'geokit'. Could the problems be related?
Current Ruby version 1.8.5 on CentOS 5.0
This might sound silly but do you have gems.rubyforge.org in your remote sources?
