react-native：无法从''... / node_modules / window-size / index.js解析模块`tty`：模块映射中不存在模块

Question

  

错误

    loading dependency graph, done.
    error: bundling failed: Error: Unable to resolve module `tty` from `/MyWorks/rnTestTrials/myCurrencySample/node_modules/window-size/index.js`: Module does not exist in the module map

    This might be related to https://github.com/facebook/react-native/issues/4968
    To resolve try the following:
      1. Clear watchman watches: `watchman watch-del-all`.
      2. Delete the `node_modules` folder: `rm -rf node_modules && npm install`.
      3. Reset Metro Bundler cache: `rm -rf /tmp/metro-bundler-cache-*` or `npm start -- --reset-cache`.  
      4. Remove haste cache: `rm -rf /tmp/haste-map-react-native-packager-*`.

我在错误中厌倦了给定的解决方案，并删除并重新启动npm  并从"./ios"删除构建并再次运行'react-native run-ios'

此应用程序工作正常，但突然显示此错误并停止工作，

厌倦了网络上所有与npm_module相关的解决方案，

  

版本

react-native-cli: 2.0.1
react-native: 0.54.0

  

的package.json

{
  "name": "myCurrencySample",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",

  },

  }
}

请帮忙，

Answer 1

我得到了与你完全相同的错误，我意识到在导入不同的模块时，我不小心从'window-size'中导入了这个“import {width};”，这通常发生在IntelliSense开启时，对于某些人来说像Visual Studio Code这样的IED导入了一行你不打算放的代码。 因此，要回答您的问题，请浏览您的文件，可能是您正在处理的最后一个文件，并检查您是否意外导入了您不打算导入的“窗口大小”模块并删除了该行代码。这就是简短的回答

如果您有太多文件要通过，那么您可以暂时删除项目目录中node_modules内的窗口大小文件夹，警告不要永久删除，保持其他安全，并确保关闭地铁捆绑窗口，然后再次运行“react-native run-android或ios”，地铁捆绑器应该通过错误，但这次，错误将准确显示项目中的哪个文件有问题，一旦找到它，删除该行代码，把窗口大小的文件夹， 然后通过运行“cd android＆amp;＆amp; ./gradlew clean”来清理你的项目，关闭metro捆绑器并再次运行“react-native run-android或ios”，它应该可以工作，

免责声明，这个答案只针对这个问题，因为“无法解决模块”错误，可能是由很多事情引起的
