使用Xcode 9和Swift 4以及vapor heroku push
/ vapor heroku init
,我收到:

在Package.swift
文件中,它说:

let package = Package(

.library(name: "App", targets: ["App"]),

除此之外,它实际上是最初的api模板项目。我错过了什么?非常感谢帮助。
答案 0 :(得分:11)
项目模板最近更新为需要Swift 4,但Heroku buildpack默认仍安装Swift 3.1.1。在更新模板以解决此问题之前,请执行以下操作:
.swift-version
的文件,其中包含4.0
。buildpack现在将安装Swift 4,你的项目将编译。
我已更新buildpack,因此不再需要上述步骤 没有固定版本的新应用程序和推送将使用Swift 4.0.2。

以上答案是完美的,我只是试图简化那些可能会感到困惑的人(比如我:D)并且有问题怎么样?
转到项目根目录。
打开该文件
$ open .swift-version
写4.0
保存该文件
完成:)

首先安装swift 4.0,然后将其设置为构建器。
swiftenv install 4.0
swiftenv local 4.0
