Gem Debugger 无法通过 bundle install 进行安装

我已经使用 rvm 安装了 ruby​​ on rails。我使用的是 2.2.0 ruby​​ 和 4.2.0 Rails。我尝试在以前的 PC 上开发的旧项目上运行 bundle install，但我得到了：

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

    /home/florin/.rvm/rubies/ruby-2.2.3/bin/ruby -r ./siteconf20151003-6297-foug8b.rb extconf.rb

Gem files will remain installed in /home/florin/.rvm/gems/ruby-2.2.3/gems/debugger-1.6.8 for inspection.
Results logged to /home/florin/.rvm/gems/ruby-2.2.3/extensions/x86_64-linux/2.2.0/debugger-1.6.8/gem_make.out
An error occurred while installing debugger (1.6.8), and Bundler cannot
continue.
Make sure that `gem install debugger -v '1.6.8'` succeeds before bundling.

通过阅读互联网，我尝试安装所有开发工具，例如：sudo apt-get install libpq-dev

sudo apt-get install libmysqlclient-dev
sudo apt-get install libpq-dev
sudo apt-get install libsqlite3-dev
sudo apt-get install libev-dev

但它不起作用。

当我从 ruby​​-1.9.3-p385 升级到 ruby​​-2.2.3 时也发生了同样的事情。

看起来当你生成项目时，Rails 会使用适合 Ruby 版本的 gem，但不能保证它们也适用于其他 Ruby 版本。

在这种情况下，调试器不支持 Ruby 2.1.1 以上版本，您可以通过以下方式替换：

gem 'debugger'

和：

gem 'byebug'

在你的 Gemfile 中。
