装载时悬挂在导轨控制台上的红宝石

Question

无论出于何种原因,rails控制台都拒绝启动,它只是挂起.我没有对我的代码进行任何更改,而使用相同版本的ruby和rails的其他项目也没有问题.当我最终按Ctrl + C时,我得到这个堆栈跟踪,指向spring.

我无法解释为什么这种情况从一个时刻发生到另一个时刻,它工作正常.我通过RVM清除了所有的宝石,并通过捆绑命令重新安装,但仍然没有运气.任何想法,将不胜感激.

此外,rails服务器没有问题,所以我可以说,问题是项目相关,但没有代码更改,它唯一的rails控制台有问题.

Ruby 2.1.2 Rails 4.1.4

Answer 1

重新启动spring应修复挂起的命令:

$ bin/spring stop

删除并重新创建新的Rails应用程序后,我经历了挂起命令(rake,bin/rails等).谷歌没那么有用.我希望这是.

重新运行命令时,Spring将自动启动.

Answer 2

当怀疑 Spring 是导致异常的原因时，尝试运行以下命令：

spring stop && spring start

Answer 3

我觉得Spring gem版本有问题.

转到你的Gemfile并评论gem'spring'.然后运行bundle install并再试一次.

# gem 'spring'

然后:

bundle install

如果您的工作取决于宝石,请尝试通过以下方式更新宝石:

bundle update
