无法激活测试单元（= 1.2.3），已激活测试单元2.3.0
最近我在 Rails 2.3.5 中添加了 rspec 测试，但我无法简单地运行 rake -T 命令。然后我发现 Rails 3 -如果我使用 RSpec，我可以删除“test”文件夹吗？ 并且我在 Gemfile 中添加了 gem test-unit。这是向我显示以下消息。
rake aborted!
can't activate test-unit (= 1.2.3), already activated test-unit-2.3.0. Make sure all dependencies are added to Gemfile.
Recently I added rspec test in my rails 2.3.5 but I wasn't able to run simply rake -T command. Then I found Rails 3 - If I'm using RSpec, can I just delete the 'test' folder? and I added gem test-unit in my Gemfile. This is showing me below message.
rake aborted!
can't activate test-unit (= 1.2.3), already activated test-unit-2.3.0. Make sure all dependencies are added to Gemfile.

You must to doing something like

这将在您的捆绑包上下文中运行 rake 命令，该命令应锁定所有 gem 的正确版本。
Try running
That will run the rake command in the context of your bundle which should lock in the correct version of all of your gems.
