heroku運行rake db：migrate dosn't work

我試圖在Heroku上遷移我的postgresql數據庫。當我運行heroku運行rake db：migrate dosn't work

heroku run rake db:migrate

我得到了錯誤：

Could not find rake-0.9.6 in any of the sources

當我運行包EXEC ...同樣的錯誤，

 $rake --version 
rake, version 10.4.2

我的Gemfile：

source 'https://rubygems.org' 


group :production do 
    gem 'pg', '0.15.1' 
    gem 'rails_12factor' 
end 
group :development, :test do 
    gem 'sqlite3' 
end 

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails' 
gem 'rails', '4.1.8' 
gem 'rake', '0.9.6' 

# Use SCSS for stylesheets 
gem 'sass-rails', '~> 4.0.3' 
# Use Uglifier as compressor for JavaScript assets 
gem 'uglifier', '>= 1.3.0' 
# Use CoffeeScript for .js.coffee assets and views 
gem 'coffee-rails', '~> 4.0.0' 
# See https://github.com/sstephenson/execjs#readme for more supported runtimes 
# gem 'therubyracer', platforms: :ruby 

# Use jquery as the JavaScript library

除非你特別需要該版本，否則我會離開Gemfile。 Bundler將使用正確的版本。

運行此命令

heroku run bundle exec rake db:migrate

這將工作。

如果不行，可能你需要卸載耙所以運行

gem uninstall rake

然後運行

bundle install

然後

bundle exec rake db:migrate
