使用旧ruby

Question

我正在使用ruby 2.1.10开展项目。它应该使用rails 4.0.13。

我正在使用rbenv。

我相信，我已经安装了所有东西。我为项目运行了bundle install。最终我让它运行。

然而，现在我得到了：

turlingdrome$ rails
Rails is not currently installed on this system. To get the latest version, simply type:

    $ sudo gem install rails

You can then rerun your "rails" command.

turlingdrome$ gem install rails -v 4.0.13
Successfully installed rails-4.0.13
Parsing documentation for rails-4.0.13
Done installing documentation for rails after 1 seconds
1 gem installed

turlingdrome$ which rails
/Users/brianp/.rbenv/shims/rails

turlingdrome$ rails -v
Rails is not currently installed on this system. To get the latest version, simply type:

    $ sudo gem install rails

You can then rerun your "rails" command.

turlingdrome$ ruby -v
ruby 2.1.10p492 (2016-04-01 revision 54464) [x86_64-darwin16.0]

如果重要，我会在运行10.12.6的Mac上运行

来自评论的ETA：

turlingdrome$ bundle exec rails -v
Rails 4.0.13

所以，bundle exec让我运行rails。 rbenv exec rails似乎也有用。

所以，问题似乎在垫片中！

Answer 1

重新垫片：

rbenv rehash

现在，您应该只能在不rails或bundle exec的情况下运行rbenv exec。
