在学习中,遇到的bug,记录一下
1.Duplicate declaration "FontText" --重复声明“FontText”
出现的原因:自己定义了一个text的类,使用时又在import中导入,解决方法:从import中删除FontText,如图
2.the<Image>componet cannot contain children.if you want to render content on top of the image ,consider using the <ImageBackground> component or absolute positioning--<图像>不能包含组合的自视图。如果你想呈现内容的形象,考虑使用< ImageBackground >组件
3.No bundle URL present.Make sure you're running a packager server or have included a .jsbundle file in your application bundle.
原因:运行时打开了翻墙软件(ShadowsocksX),只要关闭就可以
4.Type error:undefined is not an object(evaluating 'style.width')
5.Super expression error must either be null or a function
注意点在于:1.导入的react-native库的方式2.导入的js文件路径是否正确3.React.Component是否正确
6.TypeError: Cannot read property 'split' of undefined
split:为分割方法,增加未定义(空字符串)的情况即可
7.Invariant Violation:View config not found for name image.
View config not found for name XXXX. 一般就是XXXX写的有问题,如应该大写的写成了小写
8.使用TabBarIOS报错react.children.only expected to receive a single react element child
9.加载图片require(image!'tabbar_home')报错
