问题描述

我想在 Heroku 中推送我的第一个应用程序，但是我的推送失败了。我的 shell 中有这个错误；

Bundle completed (197.95s)

bla bla bla

所以，这是我的 Gemfile

source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }

ruby '2.7.2'

# Bundle edge Rails instead: gem 'rails',github: 'rails/rails'
gem 'rails','~> 6.1.0'
# Use postgresql as the database for Active Record
gem 'pg','~> 1.1'
# Use Puma as the app server
gem 'puma','~> 5.0'
# Use SCSS for stylesheets
gem 'sass-rails','>= 6'
# Transpile app-like JavaScript. Read more: https://github.com/rails/webpacker

# Use Redis adapter to run Action Cable in production

group :development,:test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug',platforms: [:mri,:mingw,:x64_mingw]
end

group :development do
  # Access an interactive console on exception pages or by calling 'console' anywhere in the code.
  gem 'web-console','>= 4.1.0'

  gem 'selenium-webdriver'
  # Easy installation and use of web drivers to run system tests with browsers

end

# Windows does not include zoneinfo files,so bundle the tzinfo-data gem
gem 'tzinfo-data',platforms: [:mingw,:mswin,:x64_mingw,:jruby]

gem 'faker'
gem 'table_print'
gem 'bootstrap'
gem 'jquery-rails'
gem 'rake'
gem 'rack-timeout'

我想我尝试了一切。这是我尝试解决此错误的方法；

  • 在我的 Gemfile 中添加 gem 'rake' 和 gem 'rack-timeout'
  • 捆绑安装
  • git commit -m "修改 Gemfile.lock"
  • 添加 RAILS_SERVE_STATIC_FILES 环境。到您的服务器。
  • RAILS_ENV=生产包 exec rake 资产：预编译 （如果我运行 RAILS_ENV=production bundle exec rake assets:precompile，我有这个）
sh: /Users/mac/Library/Mobile: No such file or directory
sh: /Users/mac/Library/Mobile: No such file or directory
Warning: you are using an unstable release of Node.js (v15.4.0). If you encounter issues with Node.js,consider switching to an Active LTS release. More info: https://docs.npmjs.com/try-the-latest-stable-version-of-node
Everything's up-to-date. nothing to do
  • git add public/assets
  • git commit -m "供应商编译的资产"
  • ...

但是没什么，我一次又一次地出现这个错误...... 如果有人可以帮助我，我将不胜感激。

谢谢。

解决方法

您能分享一下您的Gemfile.lock吗？ 我遇到了同样的问题，并通过将 PLATFORMS 从 x86_64-darwin-19 更改为 ruby 来解决它。
