Swift package: error: product dependency 'LineNoise' in package 'linenoise-swift' not found

Question

我正在使用 Swift 包管理器来管理我项目中的依赖项。我试图在我的 swift 包中导入 LineNoise，但我得到了这个：

'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，其他人正在工作（我正在以相同的方式导入它们）。我像其他包一样将包添加到我的 Package.swift 文件中，但是这个似乎不起作用...

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"]),
    ]
)

知道它有什么问题吗？为什么这个包不导入而其他包导入？

Answer 1

原因：

当软件包指定与 github 存储库名称不同的 Package.name 属性时，会发生此问题。例如。 LineNoise 的 repo 名称是 linenoise-swift 但 Package.swift says is called LineNoise。您会注意到所有其他依赖项的 github 回购名称与 package.swift 包名称一致。

修复：只将包名改为`.package`

要解决此问题，请在 Package.swift 中明确指定包依赖项的 包名称 （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，您可以使用 LineNoise 作为 package 参数。

另一个例子（Mapbox导航）：

我在使用 MapBox Navigation 库时遇到了类似的问题。文档没有像我添加其他库那样使用添加它，而是使用 specific usage:

To install the MapboxNavigation framework in another package rather than an application, run swift package init to create a Package.swift, then add the following dependency:

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

无论如何，您的 repo 似乎不再使用 lineNoise 了。

包开发人员注意事项：

确保你的 GitHub 仓库与你的包名同名，这样会更方便。
