Answer: The error message “Cannot find module ‘fs/promises'” indicates that the module ‘fs/promises’ is not installed in the current environment or it is not accessible. The ‘fs/promises’ module is a built-in module in Node.js that provides asynchronous filesystem operation methods.
To resolve this issue, you can follow these steps:
- Check Node.js version: Make sure you have a version of Node.js that supports the ‘fs/promises’ module. The ‘fs/promises’ module was introduced in Node.js version 14.0.0. You can check your Node.js version by running the following command in the terminal:
node -v
- Update Node.js: If your Node.js version is older than 14.0.0, you should consider updating to a newer version that includes the ‘fs/promises’ module. Visit the official Node.js website (https://nodejs.org) to download and install the latest version of Node.js.
- Verify module installation: If you already have a compatible version of Node.js, the ‘fs/promises’ module might not be installed properly. You can verify its installation by running the following command in the terminal:
npm list | grep fs
If the ‘fs’ module is listed in the output, it means the ‘fs/promises’ module is installed. Otherwise, you need to install it using the following command:
npm install fs
- Import the module: Once the ‘fs/promises’ module is installed, you can import it in your code using the following syntax:
const fsPromises = require('fs/promises');
Note that the ‘fs/promises’ module uses the ES6 module syntax, so make sure your environment supports it (Node.js 14+ or using a transpiler like Babel).
- Use the module: Now, you can use the asynchronous filesystem operation methods provided by the ‘fs/promises’ module. Here’s an example of reading a file using the ‘fs/promises’ module:
const fsPromises = require('fs/promises'); async function readFile(filePath) { try { const data = await fsPromises.readFile(filePath, 'utf8'); console.log(data); } catch (error) { console.error('Error reading file:', error); } } readFile('path/to/file.txt');
This code reads the content of a file asynchronously and logs it to the console. Replace ‘path/to/file.txt’ with the actual path to the file you want to read.
By following these steps, you should be able to fix the “Cannot find module ‘fs/promises'” error and use the ‘fs/promises’ module in your code.
