我想做什么，发生了什么

我在本地做了一个rails应用程序。我想把它部署到heroku。

我试过这个：

代码语言：javascript
运行
复制
$ git push heroku master

，但我收到了如下错误消息：

代码语言：javascript
运行
复制

remote:

我想要解决的

首先，我尝试了$ bundle exec rake -P，正如消息所显示的那样。

和我得到了很长的输出：

Gemfile是这样的：

代码语言：javascript
运行
复制
source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }

ruby '2.7.2'

gem 'rails', '~> 6.1.0'
gem 'puma', '~> 5.0'
gem 'sass-rails', '>= 6'
gem 'webpacker', '~> 5.0'
gem 'turbolinks', '~> 5'
gem 'jbuilder', '~> 2.7'
gem 'bootsnap', '>= 1.4.4', require: false
gem 'devise'

group :development, :test do
  gem 'sqlite3', '~> 1.4'
  gem 'byebug', platforms: [:mri, :mingw, :x64_mingw]
  gem 'rspec-rails'
  gem 'factory_bot_rails'
end

group :development do
  gem 'web-console', '>= 4.1.0'
  gem 'rack-mini-profiler', '~> 2.0'
  gem 'listen', '~> 3.3'
  gem 'spring'
  gem 'spring-commands-rspec'
end

group :test do
  gem 'capybara', '>= 3.26'
  gem 'selenium-webdriver'
  gem 'webdrivers'
end

group :production do
  gem 'pg'
end

我修改了在config/environments/production.rb中编译的资产配置

database.yml 和在这里：

代码语言：javascript
运行
复制
default: &default
  adapter: sqlite3
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
  timeout: 5000

development:
  << *default
  database: db/development.sqlite3

test:
  << *default
  database: db/test.sqlite3

production:
  << *default
  adapter: postgresql
  encoding: unicode
  pool: 5

我已经创建了heroku应用程序，并添加了git遥控器。我确实捆绑了安装并推到heroku。

代码语言：javascript
运行
复制
$ bundle install --without production
$ git add .
$ git commit -m "ready for deploying"
$ git push heroku master

然后我就发现了那个错误。

我还尝试用相同的ruby、bundler和rails版本创建新的rails应用程序。并修改了相同的东西。然后，效果很好。

对不起我的英语不好。请帮帮我。如果你需要的话我会加一些密码。谢谢。

环境

红宝石2.7.2p137 (rbenv)

  • rails 6.1.0

  • bundler 2.1.4
ruby-on-rails

我今天也有同样的问题。为了解决这个问题，我所做的就是将spring gem从development组移到我的Gemfile中的“主”组。

以前的Gemfile：

代码语言：javascript
运行
复制
ruby '2.7.2'

group :development do
  gem 'spring'
end

以前的Gemfile：

代码语言：javascript
运行
复制
ruby '2.7.2'

gem 'spring'

我希望它也适用于你。

不知道为什么会发生这个错误，但是如果在bin/rake和bin/rails中添加一个begin救援块，那么heroku就会接受它。

代码语言：javascript
运行
复制
# bin/rake  bin/rails and bin/rspec 
begin
  load File.expand_path('../spring', __FILE__)
rescue LoadError => e
  raise unless e.message.include?('spring')
end
