Question

从我的终端（Mac OSX Yosemite）运行rails s命令时，我收到以下错误：

Could not find mime-types-2.4.3 in any of the sources
Run `bundle install` to install missing gems.

当我运行捆绑安装时，我得到了使用mime-types 2.4.3＆＃39;

Using rake 10.4.2
Using i18n 0.7.0
Using json 1.8.2
Using minitest 5.5.1
Using thread_safe 0.3.4
Using tzinfo 1.2.2

Using spring 1.3.2
Using sqlite3 1.3.10
Using turbolinks 2.5.3
Using uglifier 2.7.0
Using web-console 2.0.0

但是运行＆＃39; rails s＆＃39;命令再次导致相同的错误消息：

Could not find mime-types-2.4.3 in any of the sources
Run `bundle install` to install missing gems.

这里是gemfile（我的Rails 4.2创建的默认文件）：

source 'https://rubygems.org'


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.0'
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
# Use SCSS for stylesheets

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .coffee assets and views
gem 'coffee-rails', '~> 4.1.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby

# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks

# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~> 0.4.0', group: :doc

# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'

# Use Unicorn as the app server
# gem 'unicorn'

# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development

group :development, :test do
  # Access an IRB console on exception pages or by using <%= console %> in views
  gem 'web-console', '~> 2.0'

  # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring
  gem 'spring'
end

注 - mime-types 2.4.3位于Gemfile.lock

中

关于问题可能是什么的任何想法？

感谢您的时间。

Answer 1

尝试捆绑安装--path vendor / cache

Answer 2

尝试

bundle update mime-types

然后再次运行服务器。

Rails服务器无法运行 - 找不到gem错误
