Why won t bundler install JSON gem

Question

I get the following error when attempting to run cap production deploy    DEBUG  dc362284     Bundler  GemNotFound  Could not find json-1 8 1 gem for installation DEBUG  dc362284     An error occurred while installing json  1 8 1   and Bundler cannot continue  DEBUG  dc362284     Make sure that  gem install json -v  1 8 1   succeeds before bundling    It may be important to note that this deployment was working  than I upgraded to Ruby 2 1 0 to remove an encoding error   I upgraded locally which worked fine  I ran rvm install 2 1 0 and rvm use 2 1 0 then changed my  ruby-version file to reflect this Ruby upgrade   The bundle install command works locally  but produces the same above error when I ssh onto the destination server and run this command       If I run gem list I can see this in the list of gems       jquery-rails  3 0 4  json  1 8 1  less  2 3 2        If I try the recommended solution gem install json -v  1 8 1  Locally and on the destination server I get the following output   Building native extensions   This could take a while    Successfully installed json-1 8 1 Parsing documentation for json-1 8 1 Done installing documentation for json after 0 seconds 1 gem installed   So it appears the gem is installed  right   Why is this happening  How can I solve this   Any help would be greatly appreciated

For me  some of the answers mentioned earlier were helpful from understanding point of view  but those didn t solve my problem    So this is what I did to solve issue    Modified gemfile lock to update json  2 0 2   Earlier  it was 1 8 3  Check the Bundler version installed  Bundler -v command   I had version 1 12 5 installed Install bundler version 1 11 2  using gem install bundler -v  1 11 2    Then run bundle install

I ran into this error while trying to get a project to run on my local dev box  OSX 10 6   using Sinatra and Postgresql  through activerecord   running on an rvm d ruby 2 1  I found my answer here  https   github com wayneeseguin rvm issues 2511  My exact problem  after the first block of log entries       I also get an error when trying to build native extensions for gems   The answer      rvm reinstall 2 1 0 --disable-binary   The explanation      OSX does not have a package manager so all libraries have to be installed manually by user  this makes it virtually impossible to link the binary dynamically  and as you can see there are problems with the  pseudo statically linked binary    For the sake of completeness  I had first forgotten to update rvm  rvm get head   which yielded some other errors  but still needed the --disable-binary flag once I had done so

This appears to be a bug in Bundler not recognizing the default gems installed along with ruby 2 x  I still experienced the problem even with the latest version of bundler  1 5 3    One solution is to simply delete json-1 8 1 gemspec from the default gemspec directory   rm    rubies ruby-2 1 0 lib ruby gems 2 1 0 specifications default json-1 8 1 gemspec   After doing this  bundler should have no problem locating the gem  Note that I am using chruby  If you re using some other ruby manager  you ll have to update your path accordingly

So after a half day on this and almost immediately after posting my question I found the answer   Bundler 1 5 0 has a bug where it doesn t recognize default gems as referenced here   The solution was to update to bundler 1 5 1 using gem install bundler -v    1 5 1

If the recommended answer didn t help because you are already using a newer version of bundler  Try the solution that worked for me   Delete everything inside your vendor folder   Add a line to your gemfile  gem  json    1 8 0    Then run - bundle update json   It seems to be an issue with 1 8 1 so going back to 1 8 0 did the trick for me

You should try    sudo gem install json -v  1 8 2    in my case  Ubuntu 14 04  that didn t work directly and I had to do this     sudo apt-get install ruby-dev   and then I could install the gem and continue  Had one more problem that was fixed by     sudo apt-get install libsqlite3-dev   Hoping helps

if you are in MacOS Sierra and your ruby version is 2 4 0 The ruby version is not compatible with json 1 8 3  You can try add this line in your Gemfile  gem  json   github   flori json   branch   v1 8   This works for me
