If you care about the build number (like "10B61"), especially during betas, the best place to check which version of Xcode and related SDKs you have installed is to use "System Information".
如果您关心内部版本号（如“10B61”），尤其是在测试版期间，检查您安装的 Xcode 和相关 SDK 版本的最佳位置是使用“系统信息”。
Apple Menu > About This Mac > System Report > Software > Developer
Apple 菜单 > 关于本机 > 系统报告 > 软件 > 开发人员
Once there, you'll see version and build numbers for all of the major components of the Developer Tools. The top level version and build number corresponds to the name of the disk image you downloaded from Apple.
在那里，您将看到开发人员工具的所有主要组件的版本号和内部版本号。顶级版本和内部版本号对应于您从 Apple 下载的磁盘映像的名称。
This is as of macOS 10.14.3.
这是从 macOS 10.14.3 开始的。

The simplest why I found is to run this command line:
我发现的最简单的原因是运行此命令行：
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
OR, if you have multiple XCodeversions:
或者，如果您有多个XCode版本：
sudo xcode-select -switch /Applications/Xcode<version_number>.app/Contents/Developer
fastlaneisn't able to successfully execute that command so it sounds like that you don't have an Xcode version selected for xcodebuildto run things with. Running the xcode-selectcommand above should do the trick for you ;)
fastlane无法成功执行该命令，因此听起来您没有选择用于xcodebuild运行的 Xcode 版本。运行xcode-select上面的命令应该可以为您解决问题；)
