This function is the bottom-level initialization component function of react native. To report this problem, basically only
1. Configuration error
2. The version does not correspond.
At that time, the possibility of guessing the second is relatively high.
My current RN version is 0.50.4
and in the package.json file The react native version is 0.44.1, modified to
0.50.4
