看来运行 bundle exec rake -t 可以。每 bundler.io http://bundler.io/man/bundle-exec.1.html
我建议添加 bundle exec 以确保我们使用的是当前上下文中指定的 Gem。另请参阅此 SO post。 What does bundle exec rake mean?
早先 运行 之后：sudo gem install bundler
我创建了一个 Gemfile：
gem 'rake'
gem 'rspec'
gem 'kramdown'
并做了 bundle install。现在我没有收到错误。
假设您的 Gemfile 中确实有 rspec，如果您收到此错误，则意味着您没有 运行ning rake 使用正确的 gem应用程序需要（使用应用程序根目录中的 bundle exec rake 来解决），或者您的 rspec 核心 gem 尚未安装。
如果在 运行ning bundle install 之后，您在 运行ning bundle exec rake 时仍然遇到相同的错误，请检查您是否确实安装了 "test mode" gems。这发生在我身上。
在我的例子中，我没有安装我的测试 gems 因为 Bundler 通过记住传递给 --without 选项 as noted here 的先前参数表现出非常规行为，所以它可能是你认为当你 运行 bundle install 时你正在安装你所有的 gem 但你实际上可能是 运行 （例如...） --without development test 作为好吧，不知道。
检查 bundle install 输出末尾的类似 "Gems in the groups development and test were not installed." 的内容。
要重置您的捆绑包选项，只需删除您的 ./.bundle 目录（所以... rm -r ./.bundle）。现在 bundle install 将恢复正常，抽佣应该可以正常工作了。
在生产环境中
发生的事情是，capistrano 被配置为仅在 production 组中安装 gem 包（如在 Gemfile 中）。所以它运行像 bundle install --without development test 这样的捆绑命令。
想要验证？
运行 bundle install Production环境下project目录下的命令，你会看到如下
Using devise 4.2.0
Using activeadmin 1.0.0.pre4
Using responsive_active_admin 0.0.5
Bundle complete! 60 Gemfile dependencies, 133 gems now installed.
Gems in the groups development and test were not installed.
Bundled gems are installed into /path/to/your/app/production/shared/bundle.
请注意（组开发和测试中的 Gem 未安装。）。
您可能记得您已指定 rspec-rails gem 仅在 development 模式下安装。
解决方案
尝试指定RAILS_ENV喜欢
# For Rails 5.0 +
RAILS_ENV=production bundle exec rails -T
# or
RAILS_ENV=production bundle exec rake -T
# but this may not work
bundle exec rake -T RAILS_ENV=production
我遇到这个问题是因为在我的 gem 文件中我没有指定 rspec 的版本，它得到的是旧版本。
我更新了我的 gem 文件：
gem 'rspec', '3.8.0'
成功了！
