【问题标题】：What steps are required to make the Xcode 8 Command Line Tools template build? [closed]构建 Xcode 8 命令行工具模板需要哪些步骤？ [关闭]

【问题描述】：

在 XCode 8 中没有为我构建 MacOS 命令行工具的模板项目。这是整个代码：

#import <Foundation/Foundation.h>

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        // insert code here...
        NSLog(@"Hello, World!");
    }
    return 0;
}

失败发生在导入行。错误输出的开头重现如下。

我有一台运行 El Capitan 的新机器。大约一周前，我从 GM 下载（不是应用商店）安装了 Xcode 8。

我需要做什么才能构建它？

错误输出：

【问题讨论】：

请投票结束。在这个问题中，我基本上是在问如何在 MacOS 上安装应用程序而没有意识到这一点。 Xcode 是我在我的第一台 Mac 上安装的第一个应用程序：-)。

【解决方案1】：

在`/Applications/`下安装Xcode

查看这些路径，Xcode 直接从下载目录运行，它是从 GM 种子 xip 文件中解压出来的（即它在 "/Users/ahcox/Downloads/Xcode.app/" 中）。要么手动将其复制到/Applications/，要么运行 App Store 应用程序并让它在需要的位置安装 Xcode。为了自己解决这个问题，我做了后者。有关installation of apps on MacOS 的更多信息。
