ios - 为什么我不能在Package.swift中包含SPM TSCUtility库作为依赖项？

我想在项目中包括Swift Package Manager(SPM)的TSCUtility库。

SPM的Package.swift中定义了特定的库，如下所示:

   ...
   .library(
        name: "TSCUtility",
        targets: [
            "TSCclibc",
            "TSCLibc",
            "TSCBasic",
            "TSCUtility",
        ]
    ),
    ...

构建项目时，出现以下错误:

swift build --product nfgz
'ngfz' /Users/nlykkei/Projects/ngfz: error: product dependency 'TSCUtility' not found
warning: dependency 'SwiftPM' is not used by any target

提示找不到该库。但是，如果我改为将另一个SPM库作为依赖项，例如SwiftPM，那么一切正常吗？

我的Package.swift定义如下:

// swift-tools-version:5.0
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "ngfz",
    products: [
        .executable(
            name: "ngfz",
            targets: ["ngfz"]),
    ],
    dependencies: [
        // Dependencies declare other packages that this package depends on.
        .package(url: "https://github.com/apple/swift-package-manager.git", from: "0.1.0"),
    ],
    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: "ngfz",
            dependencies: ["TSCUtility"]),
        .testTarget(
            name: "ngfzTests",
            dependencies: ["ngfz"]),
    ]
)

最佳答案

据我所知，最后标记的版本是0.4.0，其中实用程序库仍命名为SPMUtility。您可以通过声明对master分支的依赖来获取最新版本:

dependencies: [
    .package(url: "https://github.com/apple/swift-package-manager.git", .branch("master"))
],
