【问题描述】：

这是正在发生的事情，我是新手，所以如果有人能解释这意味着什么以及如何解决它，将不胜感激。尝试使用 Heroku 启动 Django 项目。在终端中输入 Foreman Start 后，这是我收到的错误：

【问题讨论】：

没有足够的信息让我们回答这个问题。这可能是 foreman 中的错误或您的错误。
您需要什么信息，也许我可以提供？

标签： ruby django python-2.7 heroku

【解决方案1】：

Ruby 版本不匹配——您的 gemset 使用的是 Ruby 2.2，但 Foreman 正在寻找 2.0。我解决问题的方法是运行

gem install foreman

对于我正在使用的 gemset。然后foreman start 将引用foreman 的本地（而不是全局）实例。

【讨论】：

【解决方案2】：

如果所有 gem 都已安装 bundle install.. 尝试运行执行 bundle exec foreman start
