如何从系统中删除RVM(Ruby版本管理器)？

Ruby最近停止了我兄弟的机器.

• gem 命令
• rails server
• rails console

全部失败,出现以下错误:

$ irb
irb(main):001:0> require 'digest/sha1'

LoadError: dlopen(~/.rbenv/versions/2.0.0-p0/lib/ruby/2.0.0/x86_64-darwin12.2.0/digest/sha1.bundle, 9): Symbol not found: _rb_Digest_SHA1_Finish

他尝试了不同版本的Ruby.重新安装一切rvm.运行rvm implode并重新安装rvm.切换到rbenv.通过安装几个红宝石ruby-build.brew install ruby.

所有人都有同样的问题.

如果他卸载了所有红宝石,操作系统提供的版本/usr/bin/ruby就可以了.但它是1.8.7.

经过数小时的故障排除后,我们得出了以下解决方案.我希望它可以帮助你避免一些痛苦.

我正在尝试(没有太大成功)rake db:migrate在rails项目上运行,但它返回:

Could not find rake-10.4.2 in any of the sources
Run bundle install to install missing gems.

我运行bundle install并且工作正常 - 安装了rake 10.4.2,但是当我跑:( rake --version由于某种原因你不能做rake -v ???)它显示:rake, version 0.9.6

我运行了捆绑更新rake并返回了我的宝石列表然后: Your bundle is updated!

为什么不进行rake更新？有什么东西我做错了(我刚开始使用rails btw - 所以这可能很简单)

任何帮助都非常感谢

我不是一个Ruby专家,但想知道发生了什么,因为我试图让指南针在节点应用程序中运行,但我的Ruby似乎已经坏了.打字:

ruby --version

得到我:

ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin13.0]

我安装了Homebrew,之前遇到过Ruby版本的问题,但它似乎已安装并正常工作.但是,当我使用gem输入请求时,我收到此错误:
