Expo:找不到模块LogReporter [英] Expo : cannot find a module LogReporter

问题描述

我已经创建了一个React Native项目，并且试图在Expo XDE中打开该项目.它将引发以下错误:

I have created a React Native Project and I was trying to open that project in Expo XDE. It throws the following error:

Cannot find module ...\node_modules\expo\tools\LogReporter

首先，我通过克隆KitchenSink项目创建了一个React Native项目. 链接:

Firstly I created a React Native project by cloning a KitchenSink Project. Link:

NativeBase-KitchenSink

NativeBase-KitchenSink

当我通过在项目根目录内发出一系列命令来启动项目时:

When I started the project by issuing series of commands inside the project root directory:

npm install然后是expo start

我发现app.json也不合适，如下所示:

I saw that the app.json was also not proper, which was the following:

{
  "name": "NativebaseKitchenSink",
  "displayName": "NativebaseKitchenSink"
}

发布expo start后，react-native报告说在当前目录中找不到app.json.

After issuing expo start react-native reported that the app.json is not to be found in the current directory.

我将app.json更改为:

I changed app.json to:

{
  "expo": {
    "name": "AwesomeProject",
    "description": "A Kitchen Sink project.",
    "slug": "AwesomeProject",
    "privacy": "public",
    "sdkVersion": "30.0.0",
    "platforms": [
      "ios",
      "android"
    ],
    "ios": {
      "supportsTablet": true
    },
    "android": {
      "package": "com.abhsax.first"
    },
    "version": "1.0.0",
    "orientation": "portrait",
    "icon": "./assets/logo.png",
    "splash": {
      "image": "./assets/splashscreen.png",
      "resizeMode": "contain",
      "backgroundColor": "#ffffff"
    },
    "updates": {
      "fallbackToCacheTimeout": 0
    },
    "assetBundlePatterns": [
      "**/*"
    ]
  }
}

当我再次发布npm install时，项目中有一些更新.然后我发出:

There were some updates in the project when I issued npm install again. Then I issued:

expo start

出现此错误:

(节点:2044)UnhandledPromiseRejection警告:错误:找不到 模块 'D:\ Projects \ ReactNativeProjects \ AwesomeProject \ node_modules \ expo \ tools \ LogReporter'

(node:2044) UnhandledPromiseRejectionWarning: Error: Cannot find module 'D:\Projects\ReactNativeProjects\AwesomeProject\node_modules\expo\tools\LogReporter'

为什么会出现此错误，该如何解决?

Why am I getting this error, and how can I fix it?

推荐答案

检查您的package.json是否包含所有必需的依赖项，并在项目的主目录中运行npm install.

check your package.json if it contains all needed dependencies and run npm install in the home directory of the project

如果缺少包，则可以使用

if a package is missing you can add it with

npm install <package_name> --save

如果您使用的是纱线，请运行:

if you are using yarn run:

yarn add expo
