谷歌云日志 Node.js React Native 中的库导入

Question

I am having difficulty importing the @google-cloud/logging npm package in my React Native project. I tried with npm install @google-cloud/logging and yarn add @google-cloud/logging but when I try to use it in my code via const {Logging} = require('@google-cloud/logging');or import {Logging} from '@google-cloud/logging'; commands I am getting a stream not found exception.

Exception:

error: Error: Unable to resolve module stream from 
C:\Users\User\Documents\repos\project\node_modules\@google-cloud\logging\build\src\index.js: 
stream could not be found within the project.

If you are sure the module exists, try these steps:
 1. Clear watchman watches: watchman watch-del-all
 2. Delete node_modules and run yarn install
 3. Reset Metro's cache: yarn start --reset-cache
 4. Remove the cache: rm -rf /tmp/metro-*

I tried deleting node_modules folder from the project and installing the packages again, resetting the Metro cache . The error still persists.

I have "react-native": "~0.63.4" and "@google-cloud/logging": "^9.6.1" in my package.json

Is there a way to implement Google Cloud Logging in a React Native project?

UPDATE 1

I resolved the stream exception with yarn add stream command. Now it asks for the fs package which I added with yarn but now I receive the following error:

Error: While trying to resolve module `fs` from file `C:\Users\User\Documents\repos\project\node_modules\@google-cloud\logging\build\src\utils\metadata.js`, the package `C:\Users\User\Documents\repos\project\node_modules\fs\package.json` was successfully found. However, this package itself specifies a `main` module field that could not be resolved (`C:\Users\User\Documents\repos\project\node_modules\fs\index.js`. Indeed, none of these files exist:

To wrap it up, @Asp1re has found a solution to solve the initial Error: Unable to resolve module stream which is running the yarn add stream command.

After that, another error occurred:

Error: While trying to resolve module `fs` from file `C:\Users\User\Documents\repos\project\node_modules\@google-cloud\logging\build\src\utils\metadata.js`, the package `C:\Users\User\Documents\repos\project\node_modules\fs\package.json` was successfully found. However, this package itself specifies a `main` module field that could not be resolved (`C:\Users\User\Documents\repos\project\node_modules\fs\index.js`. Indeed, none of these files exist

This should be solved by adding other extensions into the metro.config.js :

module.exports = {
  transformer: {
    getTransformOptions: async () => ({
      transform: {
        experimentalImportSupport: false,
        inlineRequires: false,
      },
    }),
  },
  resolver: {
    sourceExts: ['jsx', 'js', 'ts', 'tsx'], //add here
  },
};

and installing the react-native-fs . Make sure to update the requirements from fs to react-native-fs .
