尝试在heroku上部署但遇到错误

Question

我对rails上的ruby很新鲜，我一直在尝试使用git部署到heroku但我遇到错误。

我的工作环境是windows，但是使用WSL在ubuntu环境中运行ruby代码。

这是我的宝石文件

的内容

source 'https://rubygems.org'

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
  "https://github.com/#{repo_name}.git"
end

Answer 1

使用Rails 5，您不再需要rails_12factor gem。

  

以前版本的Rails要求您为项目添加gem   rails_12factor启用静态资产服务并登录Heroku。   如果要部署新应用程序，则不需要此gem。
