耙子中止，Gemfiles需要不同的耙子

Question

I am completing the tutorial Ruby on Rails 3 Essential Training through Lynda.com on Windows 7 (64 bits) using MySQL Server 5.7(64bits), MySQL Connector C 6.1 6.1.2 (32bits), Ruby 1.9.3p392 (2013-02-22) [i386-mingw32] and Rails 3.2.12.

In the training, I am in the section on "Databases and Migrations" attempting to sync the database I have created in MySQL with my Rails project, however I have been running into an abort message.

The instructor asked my class to go through Command Prompt to open up our rails project and perform a Rake to build a "schema.rb" with this code:

This is what it says now when I run "db:schema:dump"

C:\\Sites\\todo>rake db:schema:dump rake aborted!

You have already activated rake 10.1.1, but your Gemfile requires rake 10.0.3.

Using bundle exec may solve this.

C:/Sites/todo/config/boot.rb:6:in '`

C:/Sites/todo/config/application.rb:1:in '`

C:/Sites/todo/Rakefile:4:in '`

(See full trace by running task with --trace)

What do I do to get the rake that the Gemfile needs?

Answer 1

So active gem version 10.1.1, but your project have dependency 10.0.3

To solve just use bundle exec before rake db:schema:dump

bundle exec rake db:schema:dump

As you have older version at Gemfile, you can do gem uninstall rake , bundle install , this will install proper version of rake .

Answer 2

To solve this issue, I decided to delete Windows off of my computer and download a Linux distribution called Ubuntu. This completely bypassed the issue by changing the programming environment I was in and thereby accelerated me in a programming environment suitable to perform in Ruby. I didn't have to spend any money on a new computer, but I did lose about 3 months time waiting to get an answer to this question.
