Question

我一直在尝试将fluent-mysql依赖项添加到我的蒸气项目中，以便从该项目中查询单独的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时，它永远不会完成。（我已经将它放置了几个小时了），我也尝试了swift package update，但是有同样的错误。我现在可以使用vapor update了，但是仍然出现两个错误 'mysql/udf_registration_types.h' file not found with <angled> include; use "quotes" instead

和 Could not build Objective-C module 'CMySQL'

我从蒸气Web模板更改的唯一一件事是package.swift，现在是这样：

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"])
    ]
)

在此先感谢您的帮助。这是我的第一个stackOverflow问题，非常抱歉。我正在运行vapor Toolbox 3.1.7和Vapor framework 2.4.4，并且同时安装了mysql和cmysql。

Answer 1

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

如果要使用Vapor 3，则需要将所有依赖项更改为类似的内容

// 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"]),
    ]
)

Answer 2

出现这些错误的原因是因为Vapor 3不包含“ Droplet”，“ Resource”或“ ResourceRepresentable”类型。好消息是您已经成功安装了蒸气3依赖项，这是一个坏消息，要使用它们，您必须使蒸气3成为项目。好消息，蒸气3比蒸气2更出色。

在FluentMySQL 3上使用FluentMySQL
