小编eby*_*yte的帖子

当地环境：

• IDE：vscode
• 语言模式：JavasSript React

import React from 'react';

出现语法错误消息：

Replace `'react'` with `"react"`eslint(prettier/prettier)

我该如何配置它？

在.eslintrc.js

Replace `'react'` with `"react"`eslint(prettier/prettier)

谢谢您的回答。 Rules可以解决

但我想知道从哪里来@react-native-community。我没有看到这个文件。

脚蹼Hermes debugger不显示

请问如何让他正常显示\xef\xbc\x9f

react-native\xef\xbc\x9a0.62.2（从0.61更新到0.62.2）

https://fbflipper.com/

https://reactnative.dev/docs/hermes

错误信息：

Metro is connected but no Hermes apps were found.\n\nOpen a React Native screen with Hermes enabled to connect. Note: you may need to reload the app in order to reconnect the device to Metro.\n

错误消息：

一直报错，请问是什么原因？

错误是因为这行代码

item.component = () => import(`@/views/${_component}`)

如果我修改.eslintrc.js，它的工作原理

'indent' : "off",
'template-curly-spacing' : "off",

但是这样，eslint 不会帮我格式化代码

当我运行以下代码时，他无法工作，但 eslint 没有错误：

item.component = () => import(`@/views/` + _component)

"babel-core": "7.0.0-bridge.0",
"babel-eslint": "10.0.1",
"eslint": "5.15.3",

节点-v：v12.9.1

eslint -v: v6.8.0

vscode

遇到错误，但不知道如何解决？我不知道为什么会出现这个错误

我该如何定位这个错误呢？

• 系统：
  • 操作系统：Windows …

在 android\app\build.gradle 中：

project.ext.react = [
    entryFile: "index.js",
    enableHermes: false,
]

在index.js中

console.log('hermes -> ishermes', global.HermesInternal !== null);

npm run android

在日志中：

    Time    Tag Message
    18:28:15.576    ReactNativeJS   'hermes -> ishermes', true

为什么enableHermes: false但是global.HermesInternal = {}？

反应本机：0.61.5
