在 rails 6 中使用带有 rspec 的防护显示警告

Question

运行时bundle exec guard收到这些警告。

<main>:1: warning: __FILE__ in eval may not return location in binding; use Binding#source_location instead
/home/workstation/.rbenv/versions/2.7.0/lib/ruby/gems/2.7.0/gems/pry-0.12.2/lib/pry/commands/whereami.rb:40: warning: in `eval'

它显然来自 pry gem 并且在所有测试运行中看到这些都太令人沮丧了。我怎样才能隐藏这个不显示？

Answer 1

这是Pry 中特定于 Ruby 2.7 的已知上游错误。鉴于 Pry 已经有一段时间没有更新了，建议的修复（对我有用）是从 GitHub 中提取 Pry：

# Gemfile
source 'https://rubygems.org'

gem 'pry', git: 'https://github.com/pry/pry.git', ref: '272b3290b5250d28ee82a5ff65aa3b29b825e37b'
