Rails 5 - 找不到生成器“rspec:install" [英] Rails 5 - Could not find generator 'rspec:install'

问题描述

在我的 rails 5.0.0 应用程序中，我在 Gemfile 中添加了以下内容:

In my rails 5.0.0 application I've added the following to my Gemfile:

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

我运行了bundle install.然后gem就安装成功了.

I ran bundle install. Then gem was successfully installed.

然后我跑了:

rails generate rspec:install

但我收到一条错误消息:

But I got an error saying:

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.

在这个错误上发布了一大堆其他问题(找不到生成器'rspec:install')，但他们都没有为我工作，看起来我遇到了不同的问题.

There are whole bunch of other question posted on this error (Could not find generator 'rspec:install'), but none of them worked for me and it looks like I am having a different issue.

如果需要，这是我的 bundle show 输出:

推荐答案

在我的例子中，spring gem 有问题.重启spring解决了问题.

Turns out its an issue with spring gem in my case. Restarting spring solved the problem.

首先运行bin/spring status.如果 spring 正在运行，您会得到类似的结果:

First run bin/spring status. If spring is running you will get something similar:

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

这意味着你必须通过跑步来阻止 spring:

That means you have to stop spring by running:

bin/spring stop

然后重新开始:

bin/spring server

然后运行 ​​rails generate rspec:install 就可以了.

Then run rails generate rspec:install and it should work.

您可能需要运行bundle update.
