【问题描述】：
我正在尝试使用 Vapor 3 beta 和 Swift 4.1 将新的蒸汽应用程序构建部署到 Heroku，但构建过程中经常失败。我尝试在其中添加带有4.1 的.swift-version 文件，但没有运气。
还尝试使用设置新的构建包
$ heroku buildpacks:set https://github.com/vapor-community/heroku-buildpack.git
$ vapor --version
Vapor Toolbox: 3.1.4
Vapor Framework: 3.0.0-beta.3.1.3`
这些是我在终端看到的日志
$ git push heroku master

error: failed to push some refs to 'https://git.heroku.com/serene-cliffs-74861.git'`
在我的 heroku 应用程序中，我看到以下构建日志
-----> Swift app detected
-----> Installing clang 5.0.0
-----> Installing swiftenv
Cloning into 'swiftenv'...
-----> Installing Swift 4.1
We don't have build instructions for 4.1.
! Push rejected, failed to compile Swift app.
! Push failed`
谁能帮我解决这个问题。
