FATAL: Pry failed to get user input using `Readline`.
To fix this you may be able to pass input and output file descriptors to pry directly. e.g.
Pry.config.input = STDIN
Pry.config.output = STDOUT
binding.pry

It looks like you're trying to run pry inside of your application as the errors seem related.看起来您正试图在应用程序内部运行pry ，因为这些错误似乎相关。 Try to remove or comment out any occurance of binding.pry and anywhere you may have included or required pry such as in Gemfile, or if you have any require 'pry' in anything.尝试删除或注释掉任何binding.pry以及您可能包含或需要 pry 的任何地方，例如在 Gemfile 中，或者如果您有任何require 'pry' 。
Then try your command again to see if this works.然后再次尝试您的命令，看看这是否有效。
