Dependency Problem

Rails
1

I’ve seen people post similar issues at various places, but I have yet
to find an explanation on how to resolve this issue. I’m a new Rails
user, so I need a little adult supervision please.

I carelessly ran a “gem update” this morning and it updating a couple
gems. Since that point, I’ve been unable to use rails. When I attempt
to, I get the error:
“/Library/Ruby/Site/1.8/rubygems.rb:779:in ‘report_activate_error’:
RubyGem version error: builder(3.0.0 not ~> 2.1.2) (Gem::LoadError)”

There were a few additional lines. If those would be helpful in
troubleshooting this error, please let me know.

As far as I can tell, this is a dependency issue. I tried uninstalling
the builder gem and reinstalling it. That didn’t fix the error. I
tried uninstalling the rails gem and it’s dependencies and reinstalled
them all. That also didn’t fix it. I’m at a loss for what to do.

Your suggestions and guidance are appreciated.

Hello,

first try RVM, it can solve this kind of problems easily.
Plase write here your ruby, gem, rails -v versions, and output of gem
list command. What OS you use?

You can check simply ‘gem’ command gives you how you can use this
command, and also ‘gem -h’ or ‘gem --help’ If you have multiple
versions of same gems, maybe you can try gem cleanup and the name of
the gem.

Write us more details, so we can help you easier.
Good luck,
Zoltn

Do you remember the version of the gem(s) you had before you updated
them? There is a way to install specific gem versions by adding the
version at the end of the install command. Something like this:

gem install rails -v=2.3.5 # This would install Rails 2.3.5

You can also check the dependencies of the other installed gems to try
to figure out the version you might be missing. Check the
documentation at http://docs.rubygems.org/read/chapter/10#page78

All the time that i get some file (I use fetch method from app),
DragonFly
create an new file in my tmp dir.

Thanks

Hi,

I’m not sure if you’ve solved your problem yet or not, but I thought
I’d offer my experience in case you or someone else could use it.

I had an issue with running Cucumber tests after running a ‘gem
update’. The error I was getting was:

“You have already activated builder 3.0.0, but your Gemfile requires
builder 2.1.2. Consider using bundle exec.”

In the end, the solution for me was to uninstall the 3.0.0 version of
Builder by running ‘sudo gem uninstall builder -v 3.0.0’. That left
me with only the 2.1.2 version which Rails requires. Once I did that,
my Cucumber tests ran fine again.

If you no longer have the 2.1.2 version of Builder, you can get it
back by running ‘sudo gem install builder -v 2.1.2’.

HTH,
Spencer
