Ruby on rails 更新rspec gem已导致'；gem&x27；命令变得不稳定/不稳定。救命啊！

我已经安装了最新的rspec gem，现在每个“gem”命令，不管发生什么，都会抛出以下错误：

egervari@egervari:~/Websites/training$ gem -v

您使用的是什么版本的ruby和rubyems

ruby-v

---

gem-v

我在Ruby 1.9.2p0（gem版本1.7.2）下的Rails应用程序中遇到了这个问题。我通过进入（在我的情况下）/Users/smei/.rvm/gems/ruby-1.9.2-p0并删除所有rspec core 2.6.2内容，手动卸载了rspec core 2.6.2。当我卸载gem时，它没有出现在我的rspec核心版本列表中

---

然后我将rspec内核锁定到2.6.0，这就解决了问题。

我建议使用rvm来处理gem安装和ruby版本。这是一个非常棘手的问题，不知道如何帮助。似乎将生成的日期替换为“2011-05-21”可以解决这个问题。我只需要运行“sudogedit/usr/local/lib/ruby/gems/1.9.1/specifications/rspec-core-2.6.2.gemspec”。尽管如此，我还是对这种事情的发生感到失望。很难相信一个日期参数会导致整个GEM程序被破坏。考虑在同一个问题上报告一个问题，GEM-> 1.7.2，Ruby -Ruby 1.87（2011-02-18补丁级别334）[I68 6DARWIN 107.0]，MBARI 0x67 70，Ruby企业版2011.03
