【问题描述】：

我有一个带有 /javascript 和 /plugins 的供应商目录/directgory，但它们是空的，所以我也删除了它们。

我做了 git add --all 并推送了删除，但我仍然收到警告消息：

【解决方案1】：

如果您使用的是 Rails 3，那么 Heroku 在部署时会将插件注入您的代码 - 您可以通过添加来防止这种情况发生

gem rails_12factor

到您的 gemfile、捆绑、提交和重新推送。这是记录在here

【解决方案2】：

是什么

git ls-files vendor/*

显示？如果它在那里显示文件，那么你仍然有文件在那里。
