Rails 5 - 找不到生成器'rspec:install'

Question

在我的rails 5.0.0应用程序中,我已将以下内容添加到我的Gemfile中:

group :development, :test do
  gem 'byebug', platform: :mri
  gem 'rspec-rails', '~> 3.5', '>= 3.5.2'
end

我跑bundle install.然后gem成功安装.

然后我跑了以下:

rails generate rspec:install

但我得到一个错误说:

Running via Spring preloader in process 8893
Could not find generator 'rspec:install'. Maybe you meant 'css:assets', 'assets' or 'scaffold'
Run `rails generate --help` for more options.

在这个错误(Could not find generator 'rspec:install')上发布了大量其他问题,但它们都没有为我工作,看起来我有一个不同的问题.

包括它需要的,这是我的bundle show输出:

Answer 1

spring在我的案例中证明了它与gem 的问题.重启弹簧解决了这个问题.

第一次运行bin/spring status.如果弹簧正在运行,你会得到类似的东西:

Spring is running:

    8774 spring server | chessboard | started 14 mins ago   
    8808 spring app    | chessboard 6.52.08 PM | started 12 mins ago | development mode

这意味着您必须通过运行来停止弹簧:

bin/spring stop

然后再次启动它:

bin/spring server

然后运行rails generate rspec:install它应该工作.

您可能需要运行bundle update.
