ruby-on-rails - 调试器不会安装 Rails 4.1.5

Question

所以我尝试做一个bundle update，我得到了:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Make sure that gem install debugger -v '1.6.8' succeeds before bundling.

所以我尝试执行以下操作:gem install debugger -v '1.6.8' 并得到了

我有 4 个其他 Rails 应用程序都在运行 4.1.5，它们都没有问题 bundle update 所以这是怎么回事？

Answer 1

调试器 gem 不应该与 ruby 2.0+ 一起使用，并且实际上不会与 ruby 2.1.2 一起安装。您将不得不切换到 byebug .

如果你是 pry 的粉丝，还有 pry-byebug

这是我的 Gemfile 中的调试 gem 在 Rails 4 和 Ruby 2.1.2 中的样子

group :development do
    gem 'pry'
    gem 'pry-remote'
    gem 'pry-rails'
    gem 'pry-stack_explorer'
    gem 'pry-byebug'
end
