即使安装了bundler-1.1.3，“ bundle install”也会失败

Question

I'm trying to run "bundle install" and it seems to have an issue with finding the appropriate gemfile even though I installed the gem bundler. I'm not sure what to do from here. When I run "bundle install" I get this:

C:\Users\User1\Sites\simple_cms>bundle install
Fetching gem metadata from http://rubygems.org/.........
Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    rails (= 3.0.0) x86-mingw32 depends on
      bundler (~> 1.0.0) x86-mingw32

  Current Bundler version:
    bundler (1.1.3)

This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?

So then I install the bundler gem which appears to install just fine.

C:\Users\User1\Sites\simple_cms>gem install bundler
Successfully installed bundler-1.1.3
1 gem installed
Installing ri documentation for bundler-1.1.3...
Installing RDoc documentation for bundler-1.1.3...

But even though the install for the bundler gem succeeded "bundle install" still fails:

C:\Users\User1\Sites\simple_cms>bundle install
Fetching gem metadata from http://rubygems.org/.........
Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    rails (= 3.0.0) x86-mingw32 depends on
      bundler (~> 1.0.0) x86-mingw32

  Current Bundler version:
    bundler (1.1.3)

This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?

When I run "gem list" the bundler is definitely there:

C:\Users\User1\Sites\simple_cms>gem list

Answer 1

Try to remove your Gemfile.lock . Then run bundle check and see the output. It may ask you to run bundle install again.

Answer 2

It looks to me like your version of Rails (3.0.0) requires Bundler 1.0.0 -- you have a newer version.

You can install a specific version through gem install like this:

gem install bundler -v 1.0.0

Answer 3

I suggest you don't copy and paste whole projects.

First of all learn to use rvm or rbenv so you don't encounter conflicts with ruby versions and gems.

if your tutorial uses rails 3.0, you can put in something like

gem 'rails', '3.0.0'

in your Gemfile.

I suggest you install the latest rails version though and learn that.
