宝石和/或Ruby on Rails突然崩溃了，谁知道发生了什么？ [英] gem and/or Ruby on Rails broke all of a sudden, anyone know what happened?

问题描述

我有一个曾经工作的Ruby on Rails应用程序。我在一个月左右没有使用它，但是今天试着用 rails s 来启动它，并且得到了下面的错误 - 事实上，当我遇到这个错误时尝试 rails -h 或 rails -v 甚至 gem -h 或 sudo gem update --system 或任何与 gem 有关的任何内容。

 注：不推荐使用Gem :: Specification＃default_executable =。它将在2011年10月1日或之后删除。 
 Gem :: Specification＃default_executable =从/Library/Ruby/Gems/1.8/specifications/rubygems-update-1.8.2.gemspec:11调用。

任何人都知道发生了什么以及如何解决它？我怎样才能卸载它并重新安装它（不卸载我的操作系统，真的很吸引人）

通过运行清理所有已安装的gem

$ $ p $ r $ r $ r $ r $ -rf〜/ .gems $ b $ sudo rm -rf / Library / Ruby / Gems / *

在此之后 gem list 应该列出没有宝石。然后运行

  sudo gem update --system 
  

确保Ruby Gems处于最新版本。您将不得不重新安装所有的宝石。 （可能 gem install bundler 然后是 bundle install ）。

<顺便说一下，您应该查看 rbenv 或 rvm 来管理Ruby版本，并将所有开发宝石与系统Ruby分开。

I had a Ruby on Rails app that used to work. I hadn't used it in a month or so, but then tried starting it up today with rails s and got the following error—in fact, I get this error when I try rails -h or rails -v or even gem -h or sudo gem update --system or anything having to do with gem.

Anyone know what's going on and how to fix it? How can I uninstall it all and reinstall it (without uninstalling my OS, man that would really suck)

解决方案

I'd try cleaning out all your installed gems by running

rm -rf ~/.gems
sudo rm -rf /Library/Ruby/Gems/*

After this gem list should list no gems. Then run

sudo gem update --system

to ensure Ruby Gems is at the latest version. You'll then have to reinstall all your gems. (Probably gem install bundler followed by bundle install).

By the way, you should check out rbenv or rvm for managing Ruby versions and keeping all your development gems separate from the system Ruby.
