unity 项目里用了AVPro Video，打包到Mac端时报错如下：
Plugin 'AVProVideo.bundle' is used from several locations: Assets/Plugins/AVProVideo.bundle would be copied to <PluginPath>/AVProVideo.bundle Assets/Plugins/macOS/AVProVideo.bundle would be copied to <PluginPath>/AVProVideo.bundle Please fix plugin settings and try again.
原因：AVProVideo 插件在多个位置都有相同的 bundle 文件，Unity 不知道应该使用哪一个。
解决：把Assets/Plugins/AVProVideo.bundle删掉，成功打包！
