无法使用Swift 4 Package Manager导入软件包 [英] Can't import packages using Swift 4 Package Manager

问题描述

尝试在计算机上使用Xcode-beta(v9)测试Swift 4，并将软件包导入测试项目时遇到问题:

Trying to test Swift 4 using Xcode-beta (v9) on my machine and having issues with importing packages into a test project:

• 使用swift package init --type executable
启动的项目
• 更改了Package.swift并添加了2个项目进行试用:

• Initiated project using swift package init --type executable
• Changed Package.swift and added 2 projects to try out:

Package.swift

// swift-tools-version:4.0
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "sampleproject",
    dependencies: [
        // Dependencies declare other packages that this package depends on.
        // .package(url: /* package url */, from: "1.0.0"),
        .package(url: "https://github.com/IBM-Swift/Kitura.git", from: "1.7.6"),
        .package(url: "https://github.com/Alamofire/Alamofire.git", from: "4.5.0")
    ],
    targets: [
        // Targets are the basic building blocks of a package. A target can define a module or a test suite.
        // Targets can depend on other targets in this package, and on products in packages which this package depends on.
        .target(
            name: "sampleproject",
            dependencies: []),
    ]
)

• 运行swift build && swift package generate-xcodeproj
• 当我在Xcode-beta(v9)中打开项目并尝试导入Kitura或Alamofire时，出现了No such module Kitura/Alamofire错误消息
• 在终端中运行swift build会产生以下错误:
• Run swift build && swift package generate-xcodeproj
• When I open project in Xcode-beta(v9) and try to import Kitura or Alamofire, I'm getting No such module Kitura/Alamofire error message
• Running swift build in terminal produces the following error:

依赖项虚拟文件夹包含具有相同软件包名称的目录，但它们为空.但是，.build\checkouts和.build\repositories包含程序包文件夹和相应的文件.

Dependencies virtual folder contains the directories with the same package names, but they are empty. However, .build\checkouts and .build\repositories contain packages folders and corresponding files.

我的系统配置中是否缺少某些内容?

Is there something I'm missing in my system's configuration?

推荐答案

原来，我还必须将依赖项包含在Package.swift的.target中:

Turns out I had to also include the dependencies into the .target of the Package.swift:

.target(named: "sampleproject", dependencies: ["Kitura", "Alamofire"])

然后再次构建项目.
