不能激活[]的rake（= 0.9.2.2，运行时），已激活rake-10.0.2 for [] [duplicate]

This question already has an answer here:

这个问题在这里已有答案:

You have already activated X, but your Gemfile requires Y 6 answers

您已经激活了X,但您的Gemfile需要Y 6个答案

I'm trying to run a simple rake task. When I do, I get the following error:

我正在尝试运行一个简单的rake任务。当我这样做时,我收到以下错误:

can't activate rake (= 0.9.2.2, runtime) for [], already activated rake-10.0.2 for []

无法激活[]的rake(= 0.9.2.2,运行时),已激活rake-10.0.2 for []

I run the gem list command, and it lists rake as having 10.0.3, 0.9.2.2, and 0.8.7.

我运行gem list命令,它将rake列为10.0.3,0.9.2.2和0.8.7。

So, I type gem uninstall rake -v 10.0.3. According to the prompt, the uninstall was successful - but version 10.0.3 is still there when I do a gem list - and I still get the exact same problem when I try to run any rake task.

所以,我输入gem uninstall rake -v 10.0.3。根据提示,卸载是成功的 - 但是当我执行gem列表时,版本10.0.3仍然存在 - 当我尝试运行任何rake任务时,我仍然得到完全相同的问题。

Any suggestions?

Thanks in advance, Tim

You can either :

你可以:

run bundle exec rake to use the version of rake listed on your Gemfile.lock if you don't want to update it

如果您不想更新它,请运行bundle exec rake以使用Gemfile.lock上列出的rake版本

Update the version of rake used in your Gemfile.lock by running bundle update rake and then you will be able to use the command rake again !

通过运行bundle update rake更新Gemfile.lock中使用的rake版本,然后您就可以再次使用rake命令了!

#2

You probably have the older version of rake listed in your Gemfile.lock. Try to run bundle update rake, which should update everything rake-related and change your Gemfile.lock as well.

您可能在Gemfile.lock中列出了旧版本的rake。尝试运行bundle update rake,它应该更新与rake相关的所有内容并更改你的Gemfile.lock。
