3+ - `` xxx is not defined ``
4+
5+ 例如:`` Component is not defined ``
6+ 错误原因:在当前的js文件中没有定义或者没有引入这个组建,并且有调用的地方
7+
8+ - `` JSX attributes must only assigned a non-empty expression(29:28) ``
9+
10+ 错误原因:这个报错就非常简单了,已经告诉我们在哪一行了,错误原因就是,定义了之后不能为空
11+
12+ - `` Cannot read property 'Aspect' of undefined ``
13+
14+ 错误原因:没有在当前文件夹下运行`` react-native start `` ,导致一些关键的东西引入不进来
15+
16+ - `` undefined is not an object(evaluating 'Daily_Service.props.navigation') ``
17+
18+ 错误原因:一般来说,我们这样写了代码,就是因为我们认为,可以用this,或者用到某个对象的时候,但是它本身是调用不了的。
