ruby – 不能再运行rspec了
作者：互联网
我用rspec 3.0获得了ruby 2.0.我卸载了所有的rspec 3.0宝石,并用2.0替换它们.我这样做是为了摆脱弃用警告.现在,我的规格不起作用.我收到以下错误.错误告诉我什么以及如何解决？没有任何堆栈溢出帖子对此有帮助.

好的,我找到了解决办法.
我刚刚删除了所有不必要的宝石
for i in `gem list --no-versions`; do gem uninstall -aIx $i; done
然后,我刚刚使用gem install rspec重新安装rspec,它给了我rspec 3.0并解决了所有问题.但是,我再次收到了弃用警告.
请告诉我发生错误的原因.教程作者说它应该与rspec 2.10.0或更高版本一起使用.
解决方法:
The tutorial author said that it should work with rspec 2.10.0 or higher.
可能作者的意思是2.10或更高,在2.x范围内. RSpec 3.x有重大变化.
尝试像以前一样卸载gem,然后：
gem install rspec '>=2.10', '<3'
然后运行你的代码.
使用RSpec 3时发生的弃用警告并不错;他们正在指导你告诉你,你正在调用的RSpec方法将被逐步淘汰.移动整个版本号时,这些类型的警告是典型和精细的,例如2.x到3.x.
使用RSpec 2.0时出现的错误是因为这是一个非常旧的版本,并且您调用的方法在2.0中不存在.这可能是教程作者说使用2.10或更高版本的原因.
很可能该教程已经过时,因此最好的解决方案是编写教程作者并让他/她知道更新它.
