为什么我的Heroku推送被拒绝？

Question

I am working through chapter 1 of Hartl's Rails 4.0 tutorial , and I'm stuck on Section 1.4.2, which is to push a black app into GitHub and Heroku.

I tried typing git push heroku master , but I get an error message, similar to a previous question on StackOverFlow:

• Heroku push rejected - Hartl's Rails 3.2 tutorial
• Heroku push rejected, railties dependency conflict? Ruby on Rails Tutorial Section 1.4.2

It's probably the same but I don't even realize it:

-----> Ruby/Rails app detected
-----> Installing dependencies using 
       Running: bundle install --without development:test --path vendor/bundle --binstubs vendor/bundle/bin --deployment
       /usr/bin/env: ruby1.9.1: No such file or directory
 !
 !     Failed to install gems via Bundler.
 !
 !     Heroku push rejected, failed to compile Ruby/Rails app

Here is the Gemfile I used:

source 'https://rubygems.org'
ruby '1.9.3'

gem 'rails', '4.0.0.rc1'

group :development do
  gem 'sqlite3', '1.3.7'
end

gem 'sass-rails', '4.0.0.rc1'
gem 'uglifier', '2.1.1'
gem 'coffee-rails', '4.0.0'
gem 'jquery-rails', '2.2.1'
gem 'turbolinks', '1.1.1'
gem 'jbuilder', '1.0.2'

group :doc do
  gem 'sdoc', '0.3.20', require: false
end

group :production do
  gem 'pg', '0.15.1'
end

---

UPDATE : The main error seems to be /usr/bin/env: ruby1.9.1: No such file or directory Is that folder on the Heroku machine or my home computer ?

I tried removing the line ruby '1.9.3' from my .gitignore but it still returns this message.

Answer 1

First, Remove ruby 1.9.3 from the Gemfile . You don't need it and may be the cause of your problem. Start of your Gemfile should look like this:

source 'https://rubygems.org'

gem 'rails', '4.0.0.rc1'

group :development do
  gem 'sqlite3', '1.3.7'
end

etc........

Also, make sure you run

bundle install --without production 

since you are using sqlite3 in :development and postgresql in :production

I had a similar problem. The issue is that Bundler is generating stubs. Rails 4 apps do not store stubs in the app's bin/ directory. In order to fix this problem you need to use the following commands:

$ bundle config --delete bin

Then you need to update the bin directory to use the new Rails 4 executables

$ rake rails:update:bin

Then add the new bin/ directory to your version control using:

$ git add bin

Commit the changes and push your code to Heroku

i had the same problem and the problem was that i didn't chose the version of ruby that i want to use, so i did the following:

$rvm list
   ruby-1.9.3-p392 [ i686 ]
   ruby-2.0.0-p247 [ i686 ]

$rvm use  ruby-1.9.3-p392

$rvm list 
    =>   ruby-1.9.3-p392 [ i686 ]
    ruby-2.0.0-p247 [ i686 ]
