蒸气4叶子-无法解决依赖关系

如何解决蒸气4叶子-无法解决依赖关系

在使用终端创建新的蒸气项目vapor new someProjectName之后，同时还添加了流利的语言和postgres作为我的数据库...一切正常，但是，在手动添加叶子之后，我得到了无法解决依赖性错误，这是我在Package.swift文件中所拥有的：

// swift-tools-version:5.2
import PackageDescription

let package = Package(
    name: "someProjectName",platforms: [
       .macOS(.v10_15)
    ],dependencies: [
        // ? A server-side Swift web framework.
        .package(url: "https://github.com/vapor/vapor.git",from: "4.0.0"),.package(url: "https://github.com/vapor/fluent.git",.package(url: "https://github.com/vapor/fluent-postgres-driver.git",from: "2.0.0"),.package(url: "https://github.com/vapor/leaf.git",from: "3.0.0"),],targets: [
        .target(
            name: "App",dependencies: [
                .product(name: "Fluent",package: "fluent"),.product(name: "FluentPostgresDriver",package: "fluent-postgres-driver"),.product(name: "Vapor",package: "vapor"),.product(name: "Leaf",package: "leaf")
            ],swiftSettings: [
                // Enable better optimizations when building in Release configuration. Despite the use of
                // the `.unsafeFlags` construct required by SwiftPM,this flag is recommended for Release
                // builds. See <https://github.com/swift-server/guides#building-for-production> for details.
                .unsafeFlags(["-cross-module-optimization"],.when(configuration: .release))
            ]
        ),.target(name: "Run",dependencies: [.target(name: "App")]),.testTarget(name: "AppTests",dependencies: [
            .target(name: "App"),.product(name: "XCTVapor",])
    ]
)

一定是我添加了错误的叶子依赖项，并且在阅读了蒸气的文档之后，他们也没有更新文档...请让我知道是否知道答案。谢谢！

解决方法

叶子仍然在RC中，这就是为什么您无法找到任何有关它的原因。

将版本设置为4.0.0-rc，它应该可以工作
