Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

如果我这样做:捆绑安装"

If I do: "bundle install"

但是我要了

You have already activated rake 0.9.0, but your Gemfile requires rake 0.8.7

一边做

rake db:migrate

推荐答案

感谢 Dobry Den，干杯伙计.但我还没有做更多的事情.这是解决方案(对我有用).我已经添加了

I thank to Dobry Den, cheers dude. but little more I had to do. here is solution (works for me). I had added

gem 'rake','0.8.7'

在 Gemfile 上，它不存在，但我的新版本 rails 会自动安装 rake(0.9.0).

on Gemfile, which was not there, but my new version of rails automatically install rake(0.9.0).

在我通过 gem uninstall rake 删除 rake0.9.0 之后在执行 bundle update rake 之后，我可以创建和迁移数据库.

after I had delete rake0.9.0 by gem uninstall rake and after doing bundle update rake , I can create and migrate database.
