在Ubuntu WSL上构建sourcekit-lsp时出错

Question

我正在尝试在我的Ubuntu WSl上构建sourcekit-lsp。已成功安装swift-5.2.5-RELEASE-ubuntu20.04

amal@DESKTOP-CJJEUS7:~/sourcekit-lsp$swift --version
Swift version 5.2.5 (swift-5.2.5-RELEASE)
Target: x86_64-unknown-linux-gnu

并且还从主分支克隆sourcekit-lst，安装了两个sudo apt install libsqlite3-dev libncurses5-dev，按照documentation的每一步操作，但在构建时我得到了这个错误。

swift build -Xcxx -I/home/amal/swift-5.2.5-RELEASE-ubuntu20.04/usr/lib/swift -Xcxx -I/home/amal/swift-5.2.5-RELEASE-ubuntu20.04/usr/lib/swift/Block

/home/amal/sourcekit-lsp/.build/checkouts/swift-package-manager/Sources/PackageLoading/ManifestLoader.swift:530:55: error: type 'JSONEncoder.OutputFormatting' has no member 'withoutEscapingSlashes' encoder.outputFormatting = [.sortedKeys, .withoutEscapingSlashes]

你知道我做错了什么吗？请帮帮忙。

当它像这样静默地失败时，通常是因为您缺少一些依赖项。确保您安装了所有

sudo apt-get install curl clang libicu-dev git libatomic1 libxml2 \
libcurl4 zlib1g-dev libbsd0 tzdata libssl-dev libsqlite3-dev \
libblocksruntime-dev libncurses5-dev libicu-dev libblocksruntime-dev \
libpthread-workqueue-dev -y

然后，我仍然在sourcekit-lsp的main分支上失败，并出现错误

/home/rock64/Software/sourcekit-lsp/.build/checkouts/swift-package-manager/Sources/PackageLoading/ManifestLoader.swift:548:55: error: type 'JSONEncoder.OutputFormatting' has no member 'withoutEscapingSlashes'
            encoder.outputFormatting = [.sortedKeys, .withoutEscapingSlashes]
                                                     ~^~~~~~~~~~~~~~~~~~~~~~

但改用本地克隆的swift-package-manager有助于编译。我刚刚修改了sourcekit-lsp项目中Package.swift文件末尾的依赖项，以获取本地spm，如下所示

if ProcessInfo.processInfo.environment["SWIFTCI_USE_LOCAL_DEPS"] == nil {
  // Building standalone.
  package.dependencies += [
    .package(name: "IndexStoreDB", url: "https://github.com/apple/indexstore-db.git", .branch("main")),
    //.package(name: "SwiftPM", url: "https://github.com/apple/swift-package-manager.git", .branch("main")),
    .package(name: "SwiftPM", path: "/home/rock64/Software/swift-package-manager"),
    .package(url: "https://github.com/apple/swift-tools-support-core.git", .branch("main")),
    .package(url: "https://github.com/apple/swift-argument-parser.git", .upToNextMinor(from: "0.3.0")),
  ]
} else {
⋮

并在文件中删除了失败的枚举案例encoder.outputFormatting = [.sortedKeys, .withoutEscapingSlashes]

swift-package-manager/Sourcswift-package-manager/Sources/PackageLoading/ManifestLoader.swiftes/PackageLoading/ManifestLoader.swift

所以现在只剩下encoder.outputFormatting = [.sortedKeys]了

只需确保使用路径，并且不要忘记在本地克隆的swift-package-manager中提交更改

这应该可以帮助您完成编译阶段。我可以确认服务器在vim和vscode中运行良好，但由于枚举编辑，可能会有一些隐藏的小故障。稍后我将进一步研究它。
