how to solve this error when I run npm start in node.js

Question

When I run the npm start command, I get this error.

I had the latest version of npm installed but now I have installed an older one because the project is old and uses an older version of npm.this is my folder structure and my packag.json. Here is an Error message

Here is my file

I guess you need to install `module` first by typing command `npm install` — kedar sedai, Jul 04 '20 at 04:12
no it is not fixed , i can't share the code repository of git because it is private ,with the team. — Bouchra Dahamni, Jul 04 '20 at 04:34
can you show us your package.json script part and your folder structure?it seems error is coz you don't have server.js file and in your package.json you mentioned your start file as server.js and that is not available in your root folder of project. — CodeBug, Jul 04 '20 at 04:56
i edit the question with the screenshot of the package.json and folder structure. — Bouchra Dahamni, Jul 04 '20 at 07:35
Have you try this following step 1.`npm cache clean -f` 2.`npm install -g n` 3.`sudo n latest`.4. `npm start` — Jay Parmar, Jul 04 '20 at 07:59
try this step 1: `npm cache clean --force` step 2: Delete node_modules by `rm -rf node_modules package-lock.json` step 3: `npm install` and step 4 `npm start` — kedar sedai, Jul 05 '20 at 11:34

Before running npm start run npm install to install all your modules.

Most probably your project is not installed and the files are not found.

Do you have the start script specified in your config.json file? You need to write in the scripts section: "start": "node <your_main_js_file_name>".

I can already see that your server.ts is not in the root of your folder but in a subfolder. I assume it is going to be src/ or public/ or whatever so you will have to add that to your script. so for example "start": "node src/server.ts"

currently, it was like this, but I changed it, other members of my team work for them very well. "start": "node ./build/server.js".I don't know if extension of .js or .ts is the reason. I can't see the build file.But i just take it like this from github of my team. – Bouchra Dahamni Jul 04 '20 at 08:10
Thats weird because I tried it with a typescript project of mine and whenever I remove the path before server.ts where it becomes _"start" : "node server.js"_ I get the exact same error as you showed above. Maybe what you can try is installing nodemon _npm install -D nodemon_ and changing your script to _"start':"nodemon YourSubFolder/server.ts". Fingers crossed – Achraf Jul 04 '20 at 08:30
