I have an issue with the deployment of a node app to production.
When I try to execute with Node a script I get the following error:
internal/modules/cjs/loader.js:498
throw new ERR_PACKAGE_PATH_NOT_EXPORTED(basePath, mappingKey);
^

}
However when I execute this script on the testing server works fine.
We even copy and paste the node modules folder from the testing server to the production server but the error is the same.
I think is an error in some external package but I don't understand how the same configuration can have this kind of error depending on the system.
I've tried to update npm from 6.14.5 to 7.23.0 but the error persists.
Both testing and production server uses the same version of Node, 14.X
The only possibility remaining is that I'm using a different NODE_ENV variable between the 2 servers but looking at the error message it's seems unlikely.
Thanks in advance.

I've developed an electron app with following tech stack:
NodeJS (10.15) with Babel to allow ES6 import/export syntax.
Sequelize on SQLite and GraphQL to handle an internal database.
ReactJS (bundled) for views.
I've configured everything to work with Electron and running "electron" command in project root folder works without errors.
Now i'm trying to distribute it using this tutorial: https://electronjs.org/docs/tutorial/application-distribution
So i've simply downloaded the 4.1.4 binaries for windows and moved the project folder under resources/app/
But running the electron.exe i've the following error:
App threw an error during load

i've also tried to run npx electron resources/app/ from binaries folder and i've got the same error.
So i think the issue is something about the paths.
i've also tried electron-packager and the error is the same because this tool does the same process of guide above.
What can i do to fix it?
UPDATE1: after some investigations i've found that babel causes the issues. I guess when you run a project from a parent folder. I'm trying to find a solution
i've solved using this kind of configuration for babel/register:
const rootPath=path.resolve(path.join(__dirname, "../../"));
require("#babel/register")({
root: rootPath,
extends: path.join(rootPath, '.babelrc'),
ignore: [/node_modules/],
only: [rootPath],
})
I'm developing this project with TypeScript: https://github.com/scott-lin/install-npm-version
When trying to consume the package within another project, I'm getting Cannot find module 'install-npm-version' error.
Repro Steps
npm install install-npm-version#1.0.2
Create repro.js file with const inv = require('install-npm-version'); as the content
Invoke the repro with node .\repro.js
Error
> node .\repro.js

PS C:\Users\scottlin.REDMOND\Desktop\test>
The main property in the package.json file is used to find the module when using as an in-code Node module. Yours starts with a slash, implying the root directory. This is incorrect, which is why your code is failing.
To fix:
Change
"main": "/lib/Install.js",
to
"main": "lib/Install.js",
With the package.json, it's possible to do something like this
"dependencies": {
"WindowManager": "./lib/WindowManager"
},
But when trying to do this in Electron, it gives me this error:
App threw an error during load
Error: Cannot find module 'WindowManager'

Is it because of Electron, or am I doing something wrong?
./lib/WindowManager is a folder with a package.json in it with a main pointing to the WindowManager.js, so that should work.
The case you try to do normally works, make sure that the dependency "WindowManager" has been properly copied by the build tools to either:
.../desktop/node_modules/electron/dist/Electron.app/Contents/Resources/app.asar/node_modules
or
.../desktop/node_modules/electron/dist/Electron.app/Contents/Resources/node_modules
If WindowManager does not exist in the disted node_modules there is something wrong with your build process, hard to be more precise than that.
I'm building a basic MEAN webapp and am new to the stack. I have the front end running, but as soon as I add the following lines to app.js:
var mongoose = require('mongoose');
require('./models/test');
mongoose.connect('mongodb://localhost:3000/design-data-test');
I get the following error in terminal:
Error: Cannot find module 'debug'

And all of my front end code stops running. Mongodb is running on the default port.
How would I go about resolving this error?
For future visitors: You are probably missing a dependency. Make sure you run this first:
npm install
... before you run your app with npm start or node <app>
I think this may happen if you have a child dependency on debug through another package (for example express or mongoose) but you did not provide the dependencies' package.json files with the deployed application which makes node.js unable to locate debug.
I am trying to deploy a node app on Linode (Ubuntu 12.04) while following this guide from Node Knockout: http://blog.nodeknockout.com/post/9300619913/countdown-to-ko-14-deploying-your-node-js-app-to
I have no problems running the server as root, but when trying to start the server as the "deploy" user using sudo start node, I get this error:
/home/deploy/app/source/node_modules/bcrypt/node_modules/bindings/bindings.js:79

I have tried recompiling bcrypt using make clean then make since I thought my module version was incompatible with my version of node (v0.8.18), but that does not seem to be the case since I can start the server as root with no problem. I feel as though the problem lies in how I set up the deploy user, but I am not sure how to proceed.
