Why does “Cannot find module ‘ejs'” occur?
Below, are the reasons for “Cannot find module ‘ejs'” occurring:
- Module Not Installed
- Incorrect Module Name
Reason 1: Module Not Installed
In this scenario, Node.js script uses the ‘ejs’ module to read an EJS template from ‘index.ejs’, compiles it, replaces a variable with the value ‘World’, generates HTML, and writes it to ‘output.html’. But, as the module is not installed, it will give the Error as “Cannot find module ‘ejs'”. Without installing the module, we cannot use ejs.
Javascript
const ejs = require('ejs');const fs = require('fs');const template = fs.readFileSync('index.ejs', 'utf-8');const compiledTemplate = ejs.compile(template);const data = { name: 'World' };const renderedHTML = compiledTemplate(data);fs.writeFileSync('output.html', renderedHTML);console.log('HTML file generated successfully!'); |
Output:
node:internal/modules/cjs/loader:998
throw err;
^
Error: Cannot find module 'ejs'
Reason 2: Incorrect Module Name
Another reason for the error mighr be a typing mistake or incorrect naming when trying to import the ejs module. Node.js is case-sensitive, so ensure that the module name is spelled correctly.
Javascript
const ejs = require('EJS'); // Incorrect |
Output:
node:internal/modules/cjs/loader:998
throw err;
^
Error: Cannot find module 'EJS'
