我得到模块 `./index.css` 无法从 react-native 找到

Question

我在 react-native 中找不到模块 ./index.css，

我已在该位置正确导入文件。在google上搜索了很多，请帮忙。

这是错误的完整输出，

根据 React Native 文档：

您不使用特殊的语言或语法来定义样式。您只需使用 JavaScript 为您的应用程序设置样式。所有核心组件都接受一个名为 style 的道具。样式名称和值通常与 CSS 在 Web 上的工作方式相匹配，但名称使用驼峰式大小写，例如 backgroundColor 而不是 background-color。

style 属性可以是一个普通的旧 JavaScript 对象。

随着组件的复杂性增加，使用StyleSheet.create 在一个地方定义多个样式通常更简洁。这是一个例子：

import React, { Component } from 'react';
import { StyleSheet, Text, View } from 'react-native';

export default class LotsOfStyles extends Component {
  render() {
    return (
      <View>
        <Text style={styles.red}>just red</Text>
        <Text style={styles.bigblue}>just bigblue</Text>
        <Text style={[styles.bigblue, styles.red]}>bigblue, then red</Text>
        <Text style={[styles.red, styles.bigblue]}>red, then bigblue</Text>
      </View>
    );
   }
 }

const styles = StyleSheet.create({
  bigblue: {
    color: 'blue',
    fontWeight: 'bold',
    fontSize: 30,
  },
  red: {
    color: 'red',
  },
});

当然，样式不需要与组件在同一个文件中。您可以将它们抽象到一个单独的文件中，然后简单地从那里导出它们并在需要的地方导入。
