I'm trying to add a module to my project , following the doc I add this line to my index.js on my node.js project
import { bkLabs } from '@berkelium/nlp-core';
but I get the following error
SyntaxError: Cannot use import statement outside a module
at wrapSafe (internal/modules/cjs/loader.js:1001:16)
at Module._compile (internal/modules/cjs/loader.js:1049:27)
at Object.Module._extensions..js (internal/modules/cjs/loader.js:1114:10)

at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:75:12)
at internal/main/run_main_module.js:17:47
then I looked for a solution and I found that I have to change the import for a require
const bkLabs = require('@berkelium/nlp-core');
but then I get this error:
internal/modules/cjs/loader.js:1102
throw new ERR_REQUIRE_ESM(filename, parentPath, packageJsonPath);
^
Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /home/user/proyectos/chatBot/node_modules/@berkelium/nlp-core/src/index.js
require() of ES modules is not supported.
require() of /home/user/proyectos/chatBot/node_modules/@berkelium/nlp-core/src/index.js from /home/user/proyectos/chatBot/index.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 /home/user/proyectos/chatBot/node_modules/@berkelium/nlp-core/src/index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /home/user/proyectos/chatBot/node_modules/@berkelium/nlp-core/package.json.
Looks like the library you're trying to use is written with ESModule syntax and your NodeJS code with CommonJS.
You can’t require() ESM scripts; you can only import ESM scripts, like that: import {foo} from 'foo'.
This is a problem with mixing CommonJS and ESModules.
By default, nodejs uses CommonJS module syntax unless you specify "type": "module" in package.json or using .mjs exentions.
Solution, choose one that works best for you:
@berkelium/nlp-core to support hybrid-module syntax (see more information here: https://nodejs.org/api/packages.html#dual-commonjses-module-packages)the solution you've looked is correct only when you are working with node.js files, but if you want to import modules as a ES you have to specify "type": "module" in package.json
