Question

我已经和Vapor和Heroku一起工作了几个星期，而且一切顺利。蒸汽很棒！ ;]我已经使用git push heroku master成功更新Heroku上的应用程序，直到昨天晚上我开始收到此错误：

我的仓库的主分支是干净的，最新的，没有其他地方的待处理（只有代码处理）。

任何想法都会非常感激。

哈！ Vapor Slack上的那些人对它进行了分类。 pbodsk，你说得对，这是一个Swift 3.1问题。

您需要在Vapor项目的根目录中创建一个.swift-version文件。该文件的内容很简单：

3.1

当它被推送到Heroku时，它将使用正确版本的Swift进行编译。

请注意，如果您遇到此问题，还需要执行此操作：

vapor toolbox broken after upgrading swift
