Question

我确实有一个较旧的Perfect Swift项目，其中package.swift看起来如下：

// Generated automatically by Perfect Assistant Application
// Date: 2017-09-24 18:44:24 +0000
import PackageDescription
let package = Package(
    name: "SomeName",
    targets: [],
    dependencies: [
               .Package(url: "https://github.com/PerfectlySoft/Perfect-HTTPServer.git", majorVersion: 2),
               .Package(url: "https://github.com/PerfectlySoft/Perfect-LocalAuthentication-MySQL.git", majorVersion: 1),
               .Package(url: "https://github.com/PerfectlySoft/Perfect-CURL.git", majorVersion: 2),
               .Package(url: "https://github.com/SwiftORM/StORM.git", majorVersion: 3),
               .Package(url: "https://github.com/PerfectlySoft/Perfect-MySQL.git", majorVersion: 3),
               .Package(url: "https://github.com/PerfectlySoft/Perfect-SMTP.git", majorVersion: 1),
               .Package(url: "https://github.com/PerfectlySoft/Perfect-RequestLogger.git", majorVersion: 1)

    ]
)

当我运行swift package build时，得到以下输出，然后机器挂起了几个小时：

我该怎么做才能再次运行？ swift --version得到

Swift version 4.2.1-dev (LLVM 4ba03d9389, Clang 78aa734eee, Swift f4134ebef6)
Target: x86_64-unknown-linux-gnu

Answer 1

改为尝试.package(url: "package_url", from: "version")。

Answer 2

您是否尝试过更新所有内容，包括Perfect本身？考虑到您的旧项目是在不同版本的Swift下编写的，此后依赖关系可能已经发生了重大变化，而旧版本的依赖关系可能尚不支持新版本。

完成此操作后，请尝试让Perfect重新生成Package.swift，因为另一个用户指出语法已更改。
