我尝试从命令行运行Vapor应用程序的迁移。基本命令swift run App似乎不起作用。下面是一个典型的测试，比较旧的语法。

danieldonaldson@Daniels-Mac-mini wb2-web % vapor run  migrate      
This command is deprecated. Use `swift run App` instead.
Error: Invalid URL: /Volumes/500 GB Current/Current Work/wb2-web/Package.swift
danieldonaldson@Daniels-Mac-mini wb2-web % swift run App migrate
error: no executable product named 'App'

字符串
Package.swift文件位于Active Directory中，并且似乎使用名称“App”。

targets: [
        .target(
            name: "App",
            dependencies: [
                .product(name: "Vapor", package: "vapor"),
                .product(name: "FluentPostgresDriver", package: "fluent-postgres-driver"),
                .product(name: "Fluent", package: "fluent"),
                .product(name: "Leaf", package: "leaf"),
//                .product(name: "SendGrid", package: "sendgrid"),
            ],
            swiftSettings: [
                // Enable better optimizations when building in Release configuration. -- Despite the use of
                // the `.unsafeFlags` construct required by SwiftPM, this flag is recommended for Release
                // builds. See <https://github.com/swift-server/guides#building-for-production> for details.
                .unsafeFlags(["-cross-module-optimization"], .when(configuration: .release))
            ]
        ),

型
虽然在顶部，名称是不同的：

let package = Package(
    name: "Authentication",
    platforms: [
       .macOS(.v10_15)
    ],

型
但这是一个已经在几年的地方的名称，没有变化已作出.我不通常迁移或恢复手动，但在这种情况下，我必须测试一些东西.所以我不知道什么时候突然出现，但我确实需要检查这个.
为什么swift找不到应用程序的可执行文件？我相信这是相当标准的Vapor做法。
