如果没有进入我的Rails应用程序的根目录,我该如何为该应用程序执行Rails或Rake命令.
我试过了:
bundle exec rake my_tasks:do_stuff BUNDLE_GEMFILE=/PATH/TO/RAILS_APP/Gemfile
在其他组合中,无济于事.

问题实际上是双重的,bundle不知道gemfile在哪里,rake不知道要运行什么.
要使用Bundler:
BUNDLE_GEMFILE=/PATH/TO/RAILS_APP/Gemfile bundle exec ...
请注意,BUNDLE_GEMFILE必须在'bundle exec'之前.
使用Rake:
rake -f /PATH/TO/RAILS_APP/Rakefile my_task:do_stuff
要使用Rails控制台:

还没有弄清楚如何从另一个目录进入Rails控制台.查看源代码,我认为这可能是不可能的,因为它最终会执行File.join('script','rails')来启动rails进程.
我在Windows 8.1中安装了Docker Toolbox并且一直在关注安装教程.当你进入创建和推动自己想象的步骤时,我在尝试运行时遇到了这个错误docker login ....
