node.js - 构建 React 项目时出现错误 : node_modules\react-native-fs\FS. common.js : Unexpected token, 预期 ","(30:29)

Question

我刚刚在我的项目中安装了jsmediatags。然后当我尝试构建我的项目时，出现如下错误

...
Creating an optimized production build...
Failed to compile.

.\node_modules\jsmediatags\build2\ReactNativeFileReader.js
Cannot find module: 'react-native-fs'. Make sure this package is installed.

You can install this package by running: npm install react-native-fs.

然后我继续安装react-native-fs，仍然有错误。

...

./node_modules/react-native-fs/FS.common.js

当时我找不到任何文章来解决这个问题。

经过大量时间寻找解决此问题的方法后，我尝试注释 var RNFS = require('react-native-fs'); 以及 中相关的代码node_modules\jsmediatags\build2\ReactNativeFileReader.js 然后卸载 react-native-fs，它就可以工作了。

我知道这不是解决此问题的最佳方法，但也许您可以尝试一下。
