“ ./build_frameworks.sh”失败，并显示“ xcodebuild：错误：'../ AudioKit.xcodeproj”不存在

如何解决“ ./build_frameworks.sh”失败，并显示“ xcodebuild：错误：'../ AudioKit.xcodeproj”不存在

首次安装AudioKit时：

-OS X 10.15.5（19F101） -XCode版本12.0.1（12A7300）

为了他人的利益：运行./build_frameworks.sh最初抱怨：

xcode-select: error: tool 'xcodebuild' requires Xcode,but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

运行后似乎已解决：

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

再次运行它会发出很多这样的抱怨：

/Users/ali/Documents/Development/AudioKit: error: manifest parse error(s):
<module-includes>:5:9: note: in file included from <module-includes>:5:
#import "copyfile.h"
        ^

我看到作者在this Stack Overflow thread中回答了类似的问题，但是我正在Frameworks文件夹中运行脚本，所以我认为这不是我的问题...。
