我正在研究一个离子项目，我们在这个问题上遇到了很长时间：
[1230：250895] *由于未捕获的异常'NSInvalidArgumentException'而终止应用程序，原因：'* - [__ NSArrayM insertObject：atIndex：]：object不能为nil'
libc ++ abi.dylib：以NSException类型的未捕获异常终止
我们不知道错误来自何处，通过使用断点，这是错误部分：
int main(int argc, char* argv[])
{
@autoreleasepool {
int retVal = UIApplicationMain(argc, argv, nil, @"AppDelegate");
return retVal;
}
}
我相信它是一个包问题，但这里是我的package.json
