rails 命令不起作用。 出现错误“找不到 Gemfile 或 .bundle/ 目录”

Question

Whenever I try any rails command, even rails -v , I keep getting the error - Could not locate Gemfile or .bundle/ directory

Things I have already tried:

gem install rails (successfully installed)

gem update rails

gem update bundler

tried uninstalling bundler and reinstalling it.

Current ruby -v is: ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin15]

None of the above worked. Any ideas?

Answer 1

If you have installed rails successfully rails -v should work fine. For running bundle you have to be in a Gemfile directory. Are you sure you are in the root directory of your app? If not cd to your root directory and run the commands

$ rails new my_app
$ cd my_app
$ bundle

EDIT
The problem can occur if you have to be logged in as an admin user to run the command but the gemfile was in a directory under a different user.
