Failure Reason: No such file or directory
: error: Failed to read file attributes for "/Users/admin/Desktop/XXX/XXX/XXX/XXX/main/Assets.xcassets"
Failure Reason: No such file or directory
解决办法：
（1）在桌面前面文件夹中进入带有lib的路径下，将Assets文件删除，这里要进入的路径如下：
/Users/admin/Desktop/XXX/XXX/XXX/XXX/lib/class/Assets/ImagesPicker.xcassets"
（2）在工程中删除Assets.xcassets后重新导入，重新运行即可
