Path's issue with bundler, to change or not to change?

I'm trying to setup a new rails 3 project with bundler, but i ran into issues with bundler. I'm on rails 3.0.3 with ruby 1.8.7

When trying to do

$ bundle exec rake db:migrate

I get the following error

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems/dependency.rb:52:in `initialize': Valid types are [:development, :runtime], not nil (ArgumentError)

Same goes for when I try to issue a regular rake task in my terminal, one like $ rake -T i.e., only then I get the error:

uninitialized constant Bundler /Users/daniel/cc/contributie_data/Rakefile:4 (See full trace by running task with --trace)

I've been reading some other questi开发者_运维问答ons regarding this problem, therefore i've learned it has something to do with paths...

$ which rake /usr/bin/rake

$ which ruby /usr/local/bin/ruby

Can anyone give me some suggestions about what could be happening here? And even more important, how I can get bundler to play nice with rake..

Thanks for any input on this, much appreciated!

I got the same error (I'm using rvm). It turned out that in both my .profile and .bashrc was the following statement:

export PATH=~/.gem/ruby/1.8/bin:$PATH

So this path was taken instead of the rvm path. I commented these lines out and now everything works fine

Try to delete Gemfile.lock. It usually helps with

Valid types are [:development, :runtime], not nil

error.

Oh man, I just when through this today.

I did an update, and my rvm broke -- started throwing up on missing scripts and the like. I just got finished completely reinstalling rvm and my rubies.

it's not great, and it takes a while but it's what I did to get back to a working state.

Started here. How can I remove RVM (Ruby Version Manager) from my system? Ended up going through and installing fresh.

I too face the same issue and resolved it with the help of this link github:bundler

Modified a line in the file lib/bundler/resolver.rb which is reside inside bundler gem. Remove * mark from the line d = Gem::Dependency.new(base.first.name, *reqs)

like this:

reqs = [dep.requirement.as_list, base.first.version.to_s].flatten.compact
d = Gem::Dependency.new(base.first.name, *reqs)

to

reqs = [dep.requirement.as_list, base.first.version.to_s].flatten.compact
d = Gem::Dependency.new(base.first.name, reqs)

*modifying content of a gem directly is not a good practice. Posted this just to show another way to resolve this issue.
