react-native - 找不到模块：错误：无法解析“react-native/Libraries/Image/resolveAssetSource”

问题描述

我正在我当前的 react-native 项目中添加一个音频模块。我尝试安装几个模块（react-native-sound，react-native-track-player）。在两个模块中获取相同的错误输出，该输出始终指向“react-native/Libraries/Image/resolveAssetsource”，因为找不到模块。

ERROR in ./node_modules/react-native-track-player/lib/index.js
Module not found: Error: Can't resolve 'react-native/Libraries/Image/resolveAssetsource' in 'D:\workspaces\web\react\blink\node_modules\react-native-track-player\lib'
 @ ./node_modules/react-native-track-player/lib/index.js 1:401-459
 @ ./node_modules/react-native-track-player/index.js
 @ ./components/ui/BlinkAudio/BlinkAudio.web.js
 @ ./components/ui/BlinkAudio/index.web.js
 @ ./components/dialogs/ResourceDetails/ResourceDetails.js
 @ ./components/dialogs/ResourceDetails/index.js
 @ ./components/panels/catalog/CatalogPanel.js
 @ ./components/parts/Main/Main.js
 @ ./components/parts/Main/index.js
 @ ./index.web.js

这是音频模块 react-native-track-player 的索引文件中的当前导入：

import { Platform, AppRegistry, DeviceEventEmitter, NativeEventEmitter, NativeModules } from 'react-native';
import resolveAssetSource from 'react-native/Libraries/Image/resolveAssetsource';

我试图解决这个问题，包括来自“react-native”的导入的“resolveAssetsource”，如下所示：

import { 
    Platform, 
    AppRegistry, 
    DeviceEventEmitter, 
    NativeEventEmitter, 
    NativeModules, 
    resolveAssetsource 
} from 'react-native';

但我不太确定这是否是最好的方法，通常我不喜欢直接接触包节点模块。

我还尝试从 webpack 加载器中排除音频模块，但没有结果。

 module: {
    loaders: [
      {
        test: /\.js?$/,
        exclude: function (modulePath) {
          return (
            /node_modules/.test(modulePath) &&
            !/node_modules(\\|\/)react-native-track-player/.test(modulePath)
          );
        },

我想知道是否有人可以帮助我找到答案，以及是否可以处理这个 react-native 问题，因为我认为这些音频模块错误地调用了 resolveAssetsource，或者另一方面，react-native 没有不为第三方提供这个特定的库，我不知道。

解决方案

这似乎是一个语法错误问题。没有文件或模块命名，模块和文件名都是大写的。resolveAssetsourceresolveAssetSourceS

尝试删除react-native-track-player并yarn remove react-native-track-player重新安装它（或删除整个node_modules目录并yarn install再次运行），因为源代码下react-native-track-player/lib/index.js正确没有任何错误：

import { Platform, AppRegistry, DeviceEventEmitter, NativeEventEmitter, NativeModules } from 'react-native';
import resolveAssetSource from 'react-native/Libraries/Image/resolveAssetSource';

如果您在其他地方使用它，则必须像这样导入它：

import resolveAssetSource from 'react-native/Libraries/Image/resolveAssetSource';

但这不是首选的方法，因为此方法是 RN Imageclass/component的成员Image.resolveAssetSource(source)，所以最好只导入Image组件并像这样使用它：

import { 
    Platform, 
    AppRegistry, 
    DeviceEventEmitter, 
    NativeEventEmitter, 
    NativeModules, 
    Image  // Add Image import
} from 'react-native';

// and use the function as of Image method

let audioAssetSource = Image.resolveAssetSource(audioSource);

无论哪种方式，您都可以使用该方法并解析资产来源信息。
