error: could not find target(s): MyLib; use the 'path' property in the Swift 4 manifest to set a custom target path

Question

我是 运行 sudo swift test 并收到以下错误：

error: could not find target(s): MyLib; use the 'path' property in the Swift 4 manifest to set a custom target path

Package.swift:

// swift-tools-version:4.0

import PackageDescription

let package = Package(
    name: "MyLib",
    targets: [
        .target(name: "MyLib"),
        .testTarget(
            name: "MyLibTests",
            dependencies: ["MyLib"])
    ]
)

Answer 1

根据 proposal 对退出代码有影响。目的说：

These enhancements will be added to the version 4 manifest API, which will release with Swift 4. There will be no impact on packages using the version 3 manifest API. When packages update their minimum tools version to 4.0, they will need to update the manifest according to the changes in this proposal.

由于您的最低工具版本是4.0，您必须在.Target()中添加path: "path/to/sources"。

您的 Package.swift 应如下所示：

// swift-tools-version:4.0

import PackageDescription

let package = Package(
    name: "MyLib",
    targets: [
        .target(
           name: "MyLib",
           path: "Sources"), //path for target to look for sources
        .testTarget(
            name: "MyLibTests",
            dependencies: ["MyLib"],
            path: "Tests")
    ]
)
