QUESTION

Error: require() of ES modules is not supported when importing node-fetch

Asked 2022-Mar-28 at 07:04

I'm creating a program to analyze security camera streams and got stuck on the very first line. At the moment my .js file has nothing but the import of node-fetch and it gives me an error message. What am I doing wrong?

Running Ubuntu 20.04.2 LTS in Windows Subsystem for Linux.

Contents of the .js file (literally nothing but the import):

user@MYLLYTIN:~/CAMSERVER$ cat server.js 
import fetch from "node-fetch";

Result:

user@MYLLYTIN:~/CAMSERVER$ node -r esm server.js 
/home/user/CAMSERVER/node_modules/node-fetch/src/index.js:1
Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /home/user/CAMSERVER/node_modules/node-fetch/src/index.js
require() of ES modules is not supported.
require() of /home/user/CAMSERVER/node_modules/node-fetch/src/index.js from /home/user/CAMSERVER/server.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /home/user/CAMSERVER/node_modules/node-fetch/package.json.

    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1089:13) {
  code: 'ERR_REQUIRE_ESM'
}

Use ESM syntax, also use one of these methods before running the file.

  1. specify "type":"module" in package.json
  2. Or use this flag --input-type=module when running the file
  3. Or use .mjs file extension
