Ruby on Rails-Rake db：schema：dump，找不到指定的路径

Question

I'd like to dump schema of my MySql database but when i try to do it than i have error:

C:\\Users\\p\\Sites\\simple_cms>rake db:schema:dump The system cannot find the path specified.

It's my very first time with Ruby/Ruby on rails and I perform everything according "Ruby on Rails 4 Essential Training". Now i don't have any idea where i can find any solution of this problem.

Here is my Gemfile.lock:

... rake (>= 0.8.7)
  thor (>= 0.18.1, < 2.0)
rake (12.0.0)...

I can show you everything in this file if you want but its 170 lines so maybe it will be enough.

Here is my database.yml:

adapter: mysql2
encoding: utf8
pool: 5
username: dev_user
password: password
host: localhost
socket: /tmp/mysql.sock

Thanks for help!

好的，我在重新安装“ rake”后解决了该问题。
