`rails new my_app` returns "Could not locate Gemfile or .bundle/ directory"

Question

I tried creating a new Rails app, and got this error:

% bundle exec rails new my_app
Could not locate Gemfile or .bundle/ directory

I tried running bundle and got the same error.

What am I doing wrong?

Answer 1

Just leave off the bundle exec part of the command:

% bundle exec rails new my_app 
Could not locate Gemfile or .bundle/ directory

% rails new my_app
      create
      create  README.md
      create  Rakefile
      create  .ruby-version
      create  config.ru
      create  .gitignore
      create  Gemfile
         run  git init from "."
      (etc.)

In the case of generating a new rails app (something that I've only done 3-4 times in several years as a full-time Rails developer), there is no Gemfile yet...just like the error suggests. rails new my_app is probably the only command in the Rails environment that can't run under bundler.

This may be a particular gotcha if you've got an alias rails=bundle exec rails in your shell, or if your fingers are just trained to always type bundle exec for rails commands. In this case, you could remove that alias ( unalias rails ), but it's probably better to bypass the alias just this once by enclosing it in quotes:

"rails" new my_app
      create
      create  README.md
      create  Rakefile
      (etc.)

Answer 2

what about :

• rails new app_name
• cd app_name
• bundle
