mysql - 将 FluentMySQL 与 vapor 3 结合使用

Question

几天来，我一直在尝试将 fluent-mysql 依赖项添加到我的 vapor 项目中，以便从项目中查询我单独的 mysql 数据库。但是我似乎总是会遇到某种错误，例如当我尝试 vapor update它永远不会完成。 (过去我已经离开了几个小时)，我也试过swift package update但那有同样的错误。我现在处于 vapor update 的地步有效，但是我仍然遇到两个错误 'mysql/udf_registration_types.h' file not found with <angled> include; use "quotes" instead

和 Could not build Objective-C module 'CMySQL'

我从 vapor 网页模板中唯一改变的是 package.swift现在是这样的:

import PackageDescription

let package = Package(
    name: "iPadLocator",
    products: [
        .library(name: "App", targets: ["App"]),
        .executable(name: "Run", targets: ["Run"])
    ],
    dependencies: [
        .package(url: "https://github.com/vapor/vapor.git", .upToNextMajor(from: "2.2.0")),
        .package(url: "https://github.com/vapor/leaf-provider.git", .upToNextMajor(from: "1.1.0")),
        .package(url: "https://github.com/vapor/fluent-mysql.git", .upToNextMajor(from: "2.0.0"))

    ],
    targets: [
        .target(
            name: "App",
            dependencies: ["Vapor", "LeafProvider", "MySQLDriver"],
            exclude: ["Config", "Database", "Public", "Resources"]
        ),
        .target(name: "Run", dependencies: ["App"]),
        .testTarget(name: "AppTests", dependencies: ["App", "Testing"])
    ]
)

提前感谢您的任何帮助。这是我的第一个 stackOverflow 问题，很抱歉，如果它很糟糕。我在跑vapor Toolbox 3.1.7和 Vapor framework 2.4.4 , 我都有 mysql和 cmysql已安装并且是最新的。

Answer 1

您想使用 Vapor 2 还是 Vapor 3？ (忽略工具箱的版本)。如果您想要 Vapor 2，那么您拥有的是正确的 - 您只需将依赖项从 MySQLDriver 更改为 MySQLProvider。

如果你想要 Vapor 3，那么你需要将所有依赖项更改为类似

// swift-tools-version:4.0
import PackageDescription

let package = Package(
    name: "TILApp",
    dependencies: [
        // 💧 A server-side Swift web framework.
        .package(url: "https://github.com/vapor/vapor.git", from: "3.0.0"),
        .package(url: "https://github.com/vapor/fluent-mysql.git", from: "3.0.0"),
        .package(url: "https://github.com/vapor/leaf.git", from: "3.0.0-rc"),
    ],
    targets: [
        .target(name: "App", dependencies: ["FluentMySQL", "Vapor", "Leaf"]),
        .target(name: "Run", dependencies: ["App"]),
        .testTarget(name: "AppTests", dependencies: ["App"]),
    ]
)
