NativeWind 与 React Navigation 一起使用时不工作

Question

NativeWind 不起作用。当文件 tailwind.config.js 的内容为“./App,{js,jsx,ts,tsx}”时它可以工作，但自从我实现了 React Navigation 后就不再工作了。

tailwind.config.js：

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: ["./App.{js,jsx,ts,tsx}", "./screens/**/*.{js,jsx,ts,tsx}"],
  theme: {
    extend: {},
  },
  plugins: [],
}

包.json：

{
  "name": "inovarlagos",
  "version": "1.0.0",
  "main": "node_modules/expo/AppEntry.js",
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "web": "expo start --web"
  },
  "dependencies": {
    "@react-navigation/native": "^6.0.12",
    "@react-navigation/native-stack": "^6.8.0",
    "expo": "~46.0.9",
    "expo-status-bar": "~1.4.0",
    "nativewind": "^2.0.7",
    "react": "18.0.0",
    "react-native": "0.69.5",
    "react-native-safe-area-context": "4.3.1",
    "react-native-screens": "~3.15.0"
  },
  "devDependencies": {
    "@babel/core": "^7.12.9",
    "tailwindcss": "^3.1.8"
  },
  "private": true
}

应用程序.js：

import * as React from 'react';
import { View, Text } from 'react-native';
import { NavigationContainer } from '@react-navigation/native';
import { createNativeStackNavigator } from '@react-navigation/native-stack';
import HomeScreen from './screens/HomeScreen';

const Stack = createNativeStackNavigator();

function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator>
        <Stack.Screen name="Home" component={HomeScreen} />
      </Stack.Navigator>
    </NavigationContainer>
  );
}

export default App;

./screens/HomeScreen.js：

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

const HomeScreen = () => {
  return (
    <View className="flex-1 items-center justify-center bg-black">
      <Text className="text-red-200">Futuristik Lagos- Home</Text>      
    </View>
  );
};

export default HomeScreen;

结果（TailWind 不起作用）：

Answer 1

我假设您正在使用 NativeWind，因为 React Native 最近终止了对 TailwindCSS 的支持。

首先停止expo服务器。然后，不要使用 启动它expo start，而是运行expo start -c以擦除 NativeWind 添加的缓存并重新启动服务器。

Answer 2

如果您使用的是 Expo，只需将以下代码放入您的 app.js 中

import { NativeWindStyleSheet } from "nativewind";

NativeWindStyleSheet.setOutput({
  default: "native",
});
