【问题标题】：`binding.pry` causing `ArgumentError: non-absolute home``binding.pry` 导致 `ArgumentError: non-absolute home`
【发布时间】：2019-06-04 20:52:30
【问题描述】：

在什么情况下pry 可能会因此错误而失败？

ArgumentError: non-absolute home

故障点代码：

puts "ENV['HOME']: #{ENV['HOME']}"
binding.pry

堆栈跟踪：

ENV['HOME']: localhost:3000

ArgumentError: non-absolute home

更新

我发现如果我在模块顶部的require 'pry' 之后立即发出binding.pry（即不在方法内但在任何方法范围之外），那么它可以工作，ENV['HOME'] 是我们所期望的：

/Users/bart_simpson

所以现在的问题是：ENV['HOME'] 是在哪里更改为localhost:3000？？

【问题讨论】：

我不熟悉这个错误，但在谷歌上发现了一些东西：fog，net::ssh。建议打印ENV['HOME'] 或echo $HOME 的内容。
你能发布完整的堆栈跟踪吗？
github.com/pry/pry/issues/477
谢谢，我看到了 fog、net:ssh、pry/issues/477。 ENV['HOME'] 是 localhost:3000。我添加了堆栈跟踪。
更新了问题并提供了更多信息。

标签： ruby pry

【解决方案1】：

ENV['HOME'] 已被覆盖。

有人将ENV['HOME']='localhost:3000' 添加到我们的应用环境变量中。不好！

抱歉浪费了大家的时间！
