你好，我正在尝试创建一个shell脚本buildffmpeg.sh，当运行时，将下载和构建ffmpeg，所以你可以自动化的过程，使一个自定义的ffmpeg构建，最终结果是一个ffmpeg和ffprobe可执行文件。
如果你在mac或linux上运行下面的脚本，它运行得很好，但是当我在我的老版本macos10.13上测试时，我首先得到一个错误，我的ffmpeg快照url太旧了：FFMPEG_URL="https://git.ffmpeg.org/gitweb/ffmpeg.git/snapshot/74c4c539538e36d8df02de2484b045010d292f2c.tar.gz"所以我更新了var，所以它“应该”链接到ffmpeg 6. 0（最新版本，但我不确定我的链接是否正确）FFMPEG_URL="https://git.ffmpeg.org/gitweb/ffmpeg.git/snapshot/adb4688bfb0652b2ffa5bc29e53761e27e1a3b3e.tar.gz"
当我在Mac终端上使用命令$ ./buildffmpeg.sh运行下面的脚本时，它会打印出'11'，然后失败并显示错误：

...
INSTALL libavutil/ffversion.h
INSTALL libavutil/libavutil.pc
~11~
/Library/Developer/CommandLineTools/usr/bin/objdump: '/Users/apple/Documents/projects/buildffmpeghighsierra/workspace/bin/ffmpeg': No such file or directory

错误为workspace/bin/ffmpeg': No such file or directory
我的脚本构建ffmpeg的方式有什么问题吗？
