ruby-on-rails - Heroku push 被拒绝错误：无法通过 Bundler 安装 gems（可能由 mimemagic 引起）

问题描述

我尝试在heroku上推送我的项目并弹出错误消息

git push heroku master

我猜这个问题是由 rails gem mimemagic 的版本过时引起的，所以我尝试更新到最新版本，它仍然无法正常工作。

这是我的 ruby​​，Rails，mimemagic 版本

ruby -v
ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-darwin18]

rails -v
Rails 6.1.3.1

bundle info mimemagic
  * mimemagic (0.4.3)

Gemfile 中的信息

gem 'rails', '~> 6.1', '>= 6.1.0'
gem 'bundler', '~> 2.2', '>= 2.2.1.1'
gem 'mimemagic', '~> 0.4.3'

在 Gemfile.lock

 mimemagic (~> 0.4.3)

解决方案

跑步bundle update mimemagic对我有用
