TypeError：undefined 不是本机反应中的对象（正在评估“_reactNative.Stylesheet.create”）

Question

我正在用 React Native 制作一个项目，并且已经为它安装了所有依赖项，但是当我运行它显示的代码时

TypeError: undefined is not an object (evaluating '_reactNative.Stylesheet.create')

连同下面这个

• __guard 中的 node_modules/react-native/Libraries/BatchedBridge/MessageQueue.js:364:10

• node_modules/react-native/Libraries/BatchedBridge/MessageQueue.js:134:4 influshedQueue

• [本机代码]：flushedQueue 中的 null
• [本机代码]：invokeCallbackAndReturnFlushedQueue 中的 null

起初它说的是我修复的一个函数，但我不明白它在哪里引用了未定义的对象，如果有人能找到它所谈论的文件或函数，那就太好了。

请尝试这样的事情

const styles = StyleSheet.create({ 
  _container: { 
    flex: 1, 
    backgroundColor: 'blue', 
    alignItems: 'center', 
    justifyContent: 'center' 
  }, 
  get container() { 
    return this._container; 
  }, 
  set container(value) { 
    this._container = value; 
  }, 
});
