我正在尝试在 Heroku 上部署 Vapor 4 应用程序。它失败并出现以下错误：

   remote: Building source:
   remote: 
   remote: -----> Swift app detected
   remote: -----> Using Swift ’5.1.3’ (from .swift-version file)

这是我的包裹描述：

// swift-tools-version:5.1
import PackageDescription
       
let package = Package(
       name: "ashi-apns",
       platforms: [
          .macOS(.v10_15),
       ],
       dependencies: [
         // ???? A server-side Swift web framework.
          .package(url: "https://github.com/vapor/fluent.git", from: "4.0.0-rc"),
          .package(url: "https://github.com/vapor/fluent-postgresql.git", from: "2.0.0-rc"),
          .package(url: "https://github.com/vapor/vapor.git", from: "4.3.0"),

          //.package(url: "https://github.com/vapor/leaf.git", from: "4.0.0-rc"), //.product(name: "JWT", package: "jwt"), 
      ],
      targets: [
         .target(
            name: "App", 
            dependencies: [
              .product(name: "Fluent", package: "fluent"),
              .product(name: "FluentPostgresDriver", package: "fluent-postgres-driver"),
              .product(name: "Vapor", package: "vapor"),
              "APNSwift",
              .product(name: "FCM", package: "FCM"),
            ]),
               
            .target(name: "Run", dependencies: [
               .target(name: "App"),
            ]),
               
            .testTarget(name: "AppTests", dependencies: [
               .target(name: "App"),
            ])
        ]
 )

我正在使用这个 buildpack：

heroku buildpacks:set https://github.com/vapor-community/heroku-buildpack

使用相同的 buildpack，我可以部署 v3 应用。

为什么 Heroku 不能构建 Swift 5.1.3？

【问题讨论】：

【解决方案1】：

Using Swift ’5.1.3’ (from .swift-version file)

那些引用看起来很有趣。我敢打赌你的.swift-version 文件确实包含

’5.1.3’

而它应该包含

5.1.3

去掉引号，提交，再次部署。
