ruby - 错误的文件描述符错误 - 读取，当使用 nohup 在 ubuntu box 后台运行服务器时

Question

每次我尝试将 make serve 与 nohup 命令一起使用时，都会将此错误附加到 nohup.out。

我运行的nohup命令

codio@anita-doctor:~/workspace/Introduction-to-Data-Science/IntroBook$ nohup make serve &
[1] 2201
codio@anita-doctor:~/workspace/Introduction-to-Data-Science/IntroBook$ nohup: ignoring input and 
appending output to ‘nohup.out’

---

我的程序服务器在没有 nohup 的情况下使用正常的 make serve 工作正常。我正在尝试使用 nohup 在后台托管我的服务器，但是当我执行上面的代码时，出现以下错误。

附加到 nohup.out 的错误

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

任何帮助都将不胜感激，因为这对我能够在后台托管的项目至关重要。

Answer 1

看起来您正在尝试在您的应用程序内部运行 pry，因为这些错误似乎是相关的。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'任何事物。

然后再次尝试您的命令，看看是否有效。
