NoMethodError: undefined method `last_comment' after upgrading to rake 11

我遇到过上述话题中描述的问题。回顾一下，运行rake会产生以下错误：

NoMethodError: undefined method `last_comment' for #<Rake::Application:0x00000002b15ba0>

上述主题中的共识是'{1}}中不推荐使用'last_comment'方法（替换为'last_description'）。

答案声称解决方案是在Gemfile中将rake 11固定到版本10.5，仍然调用'last_comment'，或升级到rake和rake 12，其中依赖项具有已经解决了。我已经尝试了两种解决方案，但仍然会遇到同样的错误。

更新 rspec >3.5跟踪表明bundle exec正在使用rake的系统gem，其中只有2.9。如何升级系统gem或让捆绑器识别我在gem路径中指定的版本？

Answer 1

最后想出来了：Rakefile指定了rspec ~> 2.9。刚刚删除了版本号，将更新后的rspec更新为3.7，一切运行顺利。

Rake 12.3仍然产生NoMethodError：未定义的方法'last_comment'
