Pry gem被击中,但是我无法在控制台中键入任何内容

Question

它很奇怪,我没有得到任何错误信息,我只是无法使用Pry.在binding.pry被击中,和进程也会停止.但后来我实际上无法使用Pry我尝试输入,但它要么不起作用,要么它的胡言乱语而不是我正在打的关键.

关于如何Pry工作的任何想法？我正在运行Ubuntu 14.04.3 LTS,已安装的宝石列表是:

gem 'rails', '~>4.2.6'

gem 'sass-rails', '~> 5.0'

group :development do

Answer 1

• 如果您正在使用运行应用程序,则会发生这种情况foreman.这就是工头处理流程的方式.
• 一旦你达到断点,在foreman接管之前尽可能快地输入你需要的东西.

• 不幸的是,你将无法看到你输入的是什么,但只要你输入正确的东西,你应该能够看到输出.

  1. 或者,如果这是我的领班命令 foreman start -f Procfile.dev

  2. 转到foreman正在运行的文件(我的Procfile.dev),并删除运行您的rails服务器的行,对我来说,它类似于 web: rails s -b 0.0.0.0 现在rails s -b 0.0.0.0在不同的终端会话中单独运行.

  3. 您现在应该看到断点后键入的任何内容,并且可以根据需要进行调试.请注意,如果你花费太长时间foreman将接管,你将无法打字.如果是,请重新启动rails服务器.
