在相应目录中运行“bundle install”后，我得到了以下错误：
An error occurred while installing linecache19 (0.5.12), and Bundler cannot continue.
Make sure that `gem install linecache19 -v '0.5.12'` succeeds before bundling.
在尝试运行gem install linecache19 -v '0.5.12'（如上所述）时，我收到以下错误：
nishant@nishant-Inspiron-1545:~/voylla_website$ gem install linecache19 -v '0.5.12'

我现在被困住了。我接下来该怎么做。

linecache19是ruby-debug的一部分，不再支持它，需要手动处理。 在您的Gemfile中，将ruby-debug-base19和ruby-debug19替换为“gem'debugger'” 这应该可以解决问题。 在此处详细了解此信息 - https://github.com/cldwalker/debugger

对于使用Ruby＆gt; = 2.x.x 的人，请尝试使用＆＃39; byebug＆＃39;，因为＆＃39; debugger＆＃39;仅适用于ruby 1.9.2和1.9.3。
gem install 'byebug'
