ruby - `binding.pry` 导致 `ArgumentError: non-absolute home`

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binding.pry之后立即发出require 'pry'（即不在方法内但在任何方法范围之外），那么它可以工作并且ENV['HOME']是我们所期望的：

/Users/bart_simpson

所以现在的问题是：在哪里ENV['HOME']得到改变localhost:3000？？

标签： rubypry

解决方案

ENV['HOME']被覆盖。

有人添加ENV['HOME']='localhost:3000'到我们的应用程序环境变量中。坏的！

很抱歉浪费了大家的时间！
