包更新耙不是固定我“你已经激活耙...”错误(bundle update rake not fixi

当我运行rake db:migrate在Ubuntu终端我不断收到错误：

rake aborted!
You have already activated rake 10.0.4, but your Gemfile requires rake 0.9.6. Using bundle exec may solve this.

我看到计算器来解决这个问题的方法是运行：

bundle update rake

所以，我这样做，我得到：

Fetching gem metadata from https://rubygems.org/.......
Fetching gem metadata from https://rubygems.org/..
Enter your password to install the bundled RubyGems to your system: 
Using rake (0.9.6) 
Using SystemTimer (1.2.3) 
etc...
etc...

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

这难道不应该更新耙10.0.4？ 因为当我运行rake db:migrate我仍然得到错误：

rake aborted!
You have already activated rake 10.0.4, but your Gemfile requires rake 0.9.6. Using bundle exec may solve this.

任何想法我怎么能解决这个问题？ 当我运行gem env我得到：

RubyGems Environment:
  - RUBYGEMS VERSION: 1.8.15
  - RUBY VERSION: 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]

莫不是创业板PATHS一些冲突？ 谢谢你的帮助。

Answer 1:

我总是建议之前，任何此类命令使用“捆绑EXEC”

bundle exec rake db:migrate

Answer 2:

您已为问题与rvm -所以我假设你使用RVM，但是你的宝石ENV看起来并不像你所用RVM安装红宝石，做到这一点，你需要运行：

rvm use ruby --version
bundle install

RVM默认自带rubygems-bundler宝石，将自动进行bundle exec对你那么它应该是足够的：

rake db:migrate

用RVM安装红宝石之后，做出的运行下一届会议的红宝石默认：

rvm use ruby --default

在极少数情况下（如系统安装或OSX），您需要重新启动计算机，这才会生效。
