I have a project that is using express for the backend API. The project is working on my local machine but when I try to deploy it on a linux VM I get the error "Cannot find module 'Express'".
The steps I took to produce this error were cloning and cding into the repo, and running npm install. express is listed as a dependency in the package.json file. I tried explicitly running npm install express and npm install -g express and both said that they added and/or updated packages and did not return any errors. I also looked in the node_modules folder and there is an express folder there as well.
My package.json:
{
"name": "user-backend",
"version": "1.0.0",
"private": true,
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",

},
"devDependencies": {

}
}
Any help would be greatly appreciated. Thank you
This ended up being a simple syntax error in my import ("Express" vs "express")

I am using sharp to convert images to webp (project developped with angular + nodejs), it works only localy because i have error when i deploy using Cpanel (nodejs apps), i checked with different versions (latest 0.31.1, 0.27.0 and also 0.23.0 ..). I can install sharp if only i remove it from dependencies :
"dependencies": {
"sharp": "^0.27.0"
Have you any idea ?
Thanks.
Here is error :

I want to run the npm command 'npm audit fix --force', because I already ran 'npm audit fix' and there are still vulnerabilities, is there a way I can somehow fix all the vulnerabilities without breaking my program, I tried running the command in a cloned file to see what damage it would cause, and you guessed it, it broke.
Is there a way I can somehow modify the package.json and package-lock.json to fix this?
Here is my package (making a login and registration system via mongodb)

I'm working on server side coding using Node.js. I've noticed Webpack (I think) is randomly creating dist folder with .dev.js files. I'm not running build, I'm starting server with nodemon npm run start.
Image of what I'm talking about
package.json
{
"name": "card-match-game-server",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "nodemon index.js"
},
"author": "",
"license": "ISC",
"devDependencies": {
"nodemon": "^2.0.6"

"jsonwebtoken": "^8.5.1",
"lodash.shuffle": "^4.2.0",
"mongoose": "^5.11.6",
"socket.io": "^3.0.4"
}
}
Can someone clarify why those dist folders are auto generated and the purpose of it? Thanks.
To clarify the issue:
I have built a node server, which works fine. But on pushing to git and cloning elsewhere, it doesn't work in the new location.
Cleared node_modules, and tried npm install.
gitignore has only node_modules directory in it.
package.json contains the following

I'm getting the error heroku cannot find module 'Sequelize' when the server runs npm start on index.js file. When I run it locally by command heroku local it works fine. What I don't understand is that there is no module called 'Sequelize' in my project. It's called in lower case sequelize. Here's my package.json

}
My bad I was importing 'Sequelize' with uppercase. It works locally but it seems heroku is case sensitive. Changed it to 'sequelize' and it worked
