Answer 1

bundle exec rake db:migrate应解决此错误。我不久前遇到了同样的事情，这为我解决了。

Answer 2

作为旁注，RVM不再将rake安装到全局gemset中，以便与特定ruby的每个gemset一起使用。这是密切相关的，因为我们这样做是为了你可以直接通过Gemfile和/或gemset安装rake PER-PROJECT。

我们非常鼓励每个项目的.rvmrc文件，以便将每个项目的宝石与其特定的宝石集分配隔离开来。这使得A）的“默认”和/或“全局”被污染，或者B）污染其他宝石。

每个安装的Ruby应该在'global'gemset中的唯一gem应该是bundler。

rvm x.x.x@global exec rvm gemset empty && rvm x.x.x@global exec gem install bundler && rvm --create use x.x.x@mygemset && gem list -l

将非常有效地证明这一点。此外，通过这种方式，您可以有效地消除

的需要

bundle exec ...

。

Rails rake给出冲突消息（rails 3.1）
