服務(wù)器系統(tǒng)：Ubuntu Server 16.04.1 LTS 64位
-----------------------搭建Swift環(huán)境---------------------------
1.安裝所需的依賴項：

sudo apt-get install clang libicu-dev

2.下載對應(yīng)ubuntu的版本號和對應(yīng)的數(shù)字簽名

wget https://swift.org/builds/swift-4.2-release/ubuntu1604/swift-4.2-RELEASE/swift-4.2-RELEASE-ubuntu16.04.tar.gz

wget https://swift.org/builds/swift-4.2-release/ubuntu1604/swift-4.2-RELEASE/swift-4.2-RELEASE-ubuntu16.04.tar.gz.sig

3.將PGP密鑰導(dǎo)入密鑰環(huán)：

wget -q -O - https://swift.org/keys/all-keys.asc | \
  gpg --import -

4.解壓剛才下載的swift

tar xzf swift-4.2-RELEASE-ubuntu16.04.tar.gz

5.進入解壓包的swift-4.2-RELEASE-ubuntu16.04 -> usr -> bin目錄 通過以下命令獲取路徑

pwd

6.通過上一步獲取的路徑設(shè)置環(huán)境變量

sudo vi /etc/profile

//輸入 i 進入編輯模式

//在最后一行輸入
export PATH=/home/ubuntu/swift-4.2-RELEASE-ubuntu16.04/usr/bin:"${PATH}"

//按ESC退出編輯模式

//輸入:wq 保存

//刷新環(huán)境變量
source   /etc/profile

7.輸入swift --version

// 部署成功顯示如下信息
Swift version 4.2 (swift-4.2-RELEASE)
Target: x86_64-unknown-linux-gnu

8.可能會出現(xiàn)以下錯誤

// 錯誤
swift: error while loading shared libraries: libatomic.so.1: cannot open shared object file: No such file or directory

//解決方案：輸入以下命令即可
cat /etc/ld.so.conf
echo "/usr/local/lib" >> /etc/ld.so.conf
ldconfig

---------------------------------Perfect-----------------------

1.安裝庫

sudo apt-get install openssl libssl-dev uuid-dev libcurl4-openssl-dev

2.創(chuàng)建Swift軟件包

mkdir MyAwesomeProject
cd MyAwesomeProject

3.用SPM軟件包管理器初始化項目

swift package init --type=executable

這個命令會在當(dāng)前工作目錄自動生成下列文件

Creating executable package: MyAwesomeProject
Creating Package.swift
Creating README.html
Creating .gitignore
Creating Sources/
Creating Sources/MyAwesomeProject/main.swift
Creating Tests/

可能遇到這個問題 解決方案：(https://www.ics.uci.edu/~pattis/common/handouts/macmingweclipse/allexperimental/macxcodecommandlinetools.html)

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

4.然后打開Package.swift文件進行編輯

import PackageDescription

let package = Package(
    name: "LCZProjectDemo",
    dependencies: [
    .package(url: "https://github.com/PerfectlySoft/Perfect-HTTPServer.git", from: "3.0.0")
        // Dependencies declare other packages that this package depends on.
        // .package(url: /* package url */, from: "1.0.0"),
    ],
    targets: [
        // Targets are the basic building blocks of a package. A target can define a module or a test suite.
        // Targets can depend on other targets in this package, and on products in packages which this package depends on.
        .target(
            name: "LCZProjectDemo",
            dependencies: ["PerfectHTTPServer"]),
        .testTarget(
            name: "LCZProjectDemoTests",
            dependencies: ["LCZProjectDemo"]),
    ]
)

5.進行編譯和運行

swift build
.build/debug/MyAwesomeProject

效果:http://111.230.45.233:8181
