ruby-on-rails - Heroku：尽管运行 gem install bundler，但无法通过 Bundler 安装 gem

Question

当我在 heroku 上推送我的 git 时，我从 Heroku 收到以下错误：

Failed to install gems via Bundler

我试图通过运行以下命令来规避这个问题：

Gem install bundler
Gem install bundle update

但什么都没有改变。我仍然收到错误消息。在查看日志时，我可能会发现以下信息：

Warning: the running version of Bundler (1.15.2) is older than the version that created the lockfile (1.16.5). We suggest you upgrade to the latest version of Bundler by running `gem install bundler`.

remote:        inherited_resources-1.9.0 requires ruby version >= 2.3, which is incompatible
remote:        with the current version, ruby 2.2.6p396

Bundler 版本是 1.16.6，ruby 版本是 2.5.1p57，rails 版本是 4.2.8。请问我如何解决这个问题？

编辑这是 Gemfile

source 'https://rubygems.org'
