ionic 3 问题：*** 由于未捕获的异常而终止应用程序

Question

伙计们，我正在从事一个离子项目，我们在这个问题上被困了很长时间：

[1230:250895] * 由于未捕获的异常 'NSInvalidArgumentException' 导致应用程序终止，原因：'* -[__NSArrayM insertObject:atIndex:]: object cannot be 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哪里，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;
    }
}

我认为这是一个包问题，但这是我的 package.json
