快速包:错误:没有找到包'LineNoise‘中的产品依赖’linenoise‘

Question

我使用Swift软件包管理器来管理我的项目中的依赖项。我正试图在我的快速包中导入LineNoise，但我得到了以下信息：

'SwiftMC' /Users/nathanfallet/git/SwiftMC: error: product dependency 'LineNoise' in package 'linenoise-swift' not found

这不是我导入的第一个包，其他程序也在工作(我也是以同样的方式导入它们)。我和其他包一样将这个包添加到我的Package.swift文件中，但是这个包似乎不起作用.

我的Package.swift文件：

// swift-tools-version:5.2
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "SwiftMC",
    products: [
        // Products define the executables and libraries produced by a package, and make them visible to other packages.
        .library(
            name: "SwiftMC",
            targets: ["SwiftMC"]),
        .executable(
            name: "SwiftMCRun",
            targets: ["SwiftMCRun"])
    ],
    dependencies: [
        // Dependencies declare other packages that this package depends on.
        .package(url: "https://github.com/apple/swift-nio.git", from: "2.0.0"),
        .package(url: "https://github.com/adam-fowler/compress-nio.git", from: "0.0.1"),
        .package(url: "https://github.com/apple/swift-argument-parser", from: "0.0.1"),
        .package(url: "https://github.com/andybest/linenoise-swift.git", from: "0.0.1")
    ],
    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: "SwiftMC",
            dependencies: [
                .product(name: "NIO", package: "swift-nio"),
                .product(name: "CompressNIO", package: "compress-nio")
            ]),
        .target(
            name: "SwiftMCRun",
            dependencies: [
                "SwiftMC",
                .product(name: "ArgumentParser", package: "swift-argument-parser"),
                .product(name: "LineNoise", package: "linenoise-swift") // Error seems to come from here; I tried "linenoise", "LineNoise", "linenoise-swift" but nothing seems to work
            ]),
        .testTarget(
            name: "SwiftMCTests",
            dependencies: ["SwiftMC"]),
    ]
)

知道这是怎么回事吗？为什么这个包没有进口，而其他人呢？

Answer 1

原因：

当包指定与github回购名称不同的Package.name属性时，会发生此问题。例如，LineNoise的回购名称是linenoise-swift，但LineNoise。您将注意到所有其他依赖项都有与package.swift包名称一致的github名称。

Fix:只是.package的包名

要解决这个问题，请在您的中显式地指定包依赖项的包名(您可以在库package.swift文件中找到该名称)。

// Latest prerelease
.package(name: "LineNoise", url: "https://github.com/andybest/linenoise-swift", from: "0.0.3")

现在，在目标依赖项中，可以使用LineNoise作为package参数。

另一个例子(Mapbox导航)：

在使用MapBox导航库时，我遇到了类似的问题。而不是像我添加其他库那样使用添加，而是声明使用特定用途的文档

要在另一个包而不是应用程序中安装MapboxNavigation框架，请运行swift package init来创建Package.swift，然后添加以下依赖项：

// Latest prerelease
.package(name: "MapboxNavigation", url: "https://github.com/mapbox/mapbox-navigation-ios.git", .exact("2.0.0-beta.11"))

无论如何，看起来您的存储库不再使用lineNoise了。

对包开发人员的注意：

确保您的GitHub回购是相同的名称与您的包名，它将只是更方便。
