Why Error comes: In you gem list two version (10.0.2 and 0.9.2.2) of rake gem install so that this error comes.*

为什么会出现错误：在您的 gem 中列出了 rake gem 安装的两个版本（10.0.2 和 0.9.2.2），因此会出现此错误。*

Another Solution is you can do bundle update

For me, I just ran bundle updateand everything works right again.

I was able to solve this by opening up Gemfile and changing gem 'rake', '~> 0.9.2.2'to gem 'rake', '~> 10.0.1'

我能够通过打开 Gemfile 并更改gem 'rake', '~> 0.9.2.2'为gem 'rake', '~> 10.0.1'

In your Gemfile, explicitly set the latest rake version by:

在您的 中Gemfile，通过以下方式明确设置最新的 rake 版本：

gem 'rake', '~> 10.0.1'

And then run

然后运行

$ bundle update rake

Then try

回答by Rogério Alexandre

I've just ran into the same problem.

我刚刚遇到了同样的问题。

1. I inserted in my gemfilen gem 'rake', '~> 10.0.1' [in your case it should be '10.0.2']
2. I deleted my gemfile lock
3. I ran rake db:migration again and it worked.

1. 我插入了我的 gemfilen gem 'rake', '~> 10.0.1' [在你的情况下它应该是 '10.0.2']
2. 我删除了我的 gemfile 锁
3. 我再次运行 rake db:migration 并且它起作用了。

I got this tip here: Activated Ruby RAKE 10.0.1, require 10.0.0

我在这里得到了这个提示：Activated Ruby RAKE 10.0.1，需要 10.0.0

Update:In my case I didn't have rake duplicated. I just have in my gems the 10.0.1 version.

更新：就我而言，我没有重复使用耙子。我的 gems 中只有 10.0.1 版本。

Solved the same issue by running:

通过运行解决了同样的问题：

bundle update

This will update your rake gem to the latest version and allow you to run the migration.

这会将您的 rake gem 更新到最新版本并允许您运行迁移。

If you are using a gemset: be sure to run bundle installafter you've updated rake to update your local gemset as well.

如果您使用的是 gemset：请确保bundle install在更新 rake 后运行以更新您的本地 gemset。

回答by mrded

It happens because you are using rakefrom the system. (latest version by default) The solution is use follow command:

发生这种情况是因为您正在使用系统中的rake。（默认最新版本）解决方法是使用以下命令：

bundle exec rake db:migrate

Also, you can create alias. Because this command is too big and difficult to write.

此外，您可以创建别名。因为这个命令太大，很难写。

echo "alias be='bundle exec'" >> ~/.bash_profile
source ~/.bash_profile

Then you can use follow short command:

然后您可以使用以下简短命令：

be rake db:migrate

回答by Richard Chen

change the version which located both in the gemfile and gemlock to the version number shown in the console, it will be done

将位于 gemfile 和 gemlock 中的版本更改为控制台中显示的版本号，它将完成
