I installed haml 2.2 on a Spree application with
rake gems:install
After placing it in my environment.rb .
Just like I thought, nothing loads anymore. Spree seems to be very exclusive about their source code.
Does anyone know anyway I can delete haml and restore my project?
Go to your config/environment.rb. If you see:
config.gem haml
remove that line.
If you're sure that HAML is not in environment.rb anymore, check that it's not installed as a plugin in vendor/plugins and finally uninstall the gem (sudo gem uninstall haml).

I have installed ajax_pagination gem from https://github.com/ronalchn/ajax_pagination
When I restart my server i get this message
couldn't find file 'history'
(in
/Users/user/.rvm/gems/ruby-1.9.3-p362/gems/ajax_pagination-0.6.3/lib/assets/javascripts/ajax_pagination.js.erb:3)
and inserted calls in assets manifests, rails version is 3.2.8
I had tried installing a history gem ( https://github.com/philostler/historyjs-rails ) or adding history.js to assets but nothing helps
Thanks for any help!
I had the same issue, all you need to do is:
Add gem 'jquery-historyjs' to your Gemfile,
Run bundle install
Then rails generate historyjs:install
This appears to be a bug in the jquery-historyjs gem, which ajax_pagination depends on. You may want to report an issue on their github repo.
As a work-around, you could create a blank history.js file in app/assets/javascripts and try bringing in historyjs-rails.
I have strange old buggy project on Rails 2.
It have gem's dependencies in config/environment.rb like
config.gem "andand"
config.gem "json"
config.gem "chronic"
config.gem "mini_fb"
all those gems are located in vendor/gems/
andand-1.3.3/
chronic-0.6.7/
json-1.7.3/
mini_fb-1.1.7/
rbet-1.0.3/
redis-3.0.1/
responsys_client-0.0.1/
but when i start unicorn server with this app it always complain that it can't find this gems. Why?
UPDATE
After building and installing gem from vendor/gems rails still complain about it.
I have tweake mini_fb gem into custom mini_fb_custom gem. Changed all references in gemspec and other files from mini_fb to mini_fb_my, installed it and it is shown in gem list as mini_fb_my. But it fails to load from config/environment.rb and complains that
Missing these required gems:
mini_fb_my >= 0
maybe i should rename lib/mini_fb.rb to lib/mini_fb_my.rb
i'll check it.
UPDATE 2
Yes, renaming files rocks!
You still need to install them from those folders, or unicorn will not know where to look for them.
Just install the gems from that directory and unicorn should pick them up.
UPDATE
You can install your gems locally with this command
gem install --local vendor/gems/gem/gem-name.gem
On more recent versions of rails you just specify path on the Gemfile
gem "gem-name", path: "path/to/gem"
My advice: replace the obsolete gem configuration with bundler (it works fine with rails 2, there should be a tutorial for rails 2 available on their website).
Configuration through gem command, freezing gems, etc. is just pain in the a** and it seemed kinda buggy to me when I'd used it (long time ago).
Without a file extension I can't get syntax highlighting to persist. That's not the end of the world, but I'd appreciate having it.
Will it break Rails if I rename Gemfile as Gemfile.rb ?
It looks like you can rename it, but bundler will not automatically find it.
However, you can just prepend every bundler command with BUNDLE_GEMFILE=Gemfile.rb and it'll work:
BUNDLE_GEMFILE=Gemfile.rb bundle install
You might also look at http://gembundler.com/man/bundle-config.1.html -- It mentions a gemfile option, but I couldn't get it to work (even after manually setting it to Gemfile.rb, it still tried to look for Gemfile).
I tried rake gems:unpack, it worked for most gems, but facebooker gem doesn't get frozen.
How to freeze it?
Thanks
The answer is simple...
Apparently when in your environment.rb you included several gems, and one of the gems is broken or included with wrong syntax (perhaps it needs lib options for example config.gem "ruby-openid", :lib => "openid") all the gems below that gem won't be unpacked. Funny though how Rails doesn't return an error when you ruby script/server it.
I have the following gems defined in my environment.rb file:
config.gem "authlogic"
config.gem "paperclip"
config.gem "pauldix-feedzirra", :lib => "feedzirra", :source => "http://gems.github.com"
config.gem 'whenever', :lib => false, :source => 'http://gemcutter.org/'
I have them installed on my local computer and everything is working well.
Since I am working on a shared-server (DreamHost), I need to unpack those gems to get them to work (can't install them as I did on my own computer to get them to work).
Before uploading, I ran the following on my local machine:
rake gems:unpack
This created the following folders in /vender/gems:
authlogic-2.1.3, paperclip-2.3.1.1, pauldix-feedzirra-0.0.18, whenever-0.4.1
So it looks like they're all there.
When I run rake db:migrate on the server, though, I get these following error:
Missing these required gems:
pauldix-feedzirra
For some reason, the feedzirra unpacked gem is not detected. Could anybody offer a clue as to why this is happening and a potential solution?
Thanks!
EDIT: Thanks, but the code to put in environment.rb doesn't work, and bundler won't install properly on my server. Any other suggestions?
This isn't exactly an answer, but since I could never get config.gem to work properly, I recommend using Bundler whenever I can. It just works and it handles interdependencies between gems well. It also replaces config.gem in Rails 3 from what I understand.
I notice two things about feedzirra: first, it depends on 3 other gems, and at least one of those build native extensions. And I'm going to call it "feedzirra" - I'm not a fan of github's ill-considered autopackaging fiasco.
If it were only the former, then rake gems:unpack:dependencies would do the trick.
However, at least curb (which feedzirra depends on) is building extensions, and those can't simply be unpacked. You could either get Dreamhost to install them (good luck) or install them into your user's local gem directory.
To do that, you'll need to update your .gemrc and be sure that it includes a line like:
:user_install: true
Then rake gems:install
Unless your deployment environment won't let you build executables, in which case you'll need to shell out for a less restricted package - I know for a fact that Dreamhost does provide packages that will allow for extension-gems.
(And there's the separate issue of libcurl being deployed...)
Try Following.put this code in envoirment.rb
config.load_paths += Dir["#{RAILS_ROOT}/vendor/gems/**"].map do |dir|
File.directory?(lib = "#{dir}/lib") ? lib : dir
end
Don't know if my hints are useful, because feedzirra is compiled extension (against CURL i think). Better solution is to normally install feedzirra gem (it will compile itself) on your server.
You have not installed (unpacked) feedzirra gem, but pauldix-feedzirra. Probably you need feedzirra unpacked too.
Try to add
config.gem feedzirra
into environment.rb and run locally
rake gems:install
rake gems:unpack
It looks like feedzirra unpacked gem is missing in /vendor/plugins. Look if feedzirra will be copied there after those commands...
