pod 失败，需要修改podfile

[zuohuachen]

use_frameworks!

platform :osx, '10.11'

target 'FFmpegTutorial-macOS' do
  pod 'FFmpegTutorial',:path => '../../'
end

pre_install do |installer|
  puts `../../download-vendor.sh macos 0.10.1-230831144049-ijk`
end

如上，PodFile文件只有一个打印puts，没执行 sh文件。把它改成下面这样，就可以执行pod install了。

pre_install do |installer|
  podfile_path = File.dirname(File.realpath(__FILE__))
  script_relative_path = "../../download-vendor.sh"
  script_full_path = File.expand_path(script_relative_path, podfile_path)
  system("sh #{script_full_path} ios 0.10.1-230831144049-ijk")
end

不是啊，这里使用了最简单的反引号方式调用了 shell ，然后通过 puts 把执行日志打印出来。
你可以看下这个：https://stackoverflow.com/questions/2232/how-to-call-shell-commands-from-ruby
麻烦改回去再试试，看下具体原因。

环境：
ruby 2.6.10p210 (2022-04-12 revision 67958) [universal.arm64e-darwin23]
pod --version 1.13.0

报错原因：（但如果改成正常引号，可以正常执行）

我知道了，是执行脚本时的目录不对，使用下面的步骤安装即可。

git clone https://github.com/debugly/FFmpegTutorial.git
cd FFmpegTutorial/Example/macOS
pod install
open FFmpegTutorial-macOS.xcworkspace

优化了脚本，现在可以 pod install --project-directory=Example/MacOS 了。
