Answer 1

Look into your project directory where you initialized node app.js . The issue is that you're not in the project directory where this file exists. Go into the project directory and launch your node app.js .

90% sure, hopefully this will fix it.

Answer 2

This error usually occurs when you're not in the right folder. Here you're in C:\Program Files\nodejs\node_modules\npm and you're trying to run your file App.js which is stored elsewhere on your computer.

I'd recommend going through these simple steps to fix the problem: (let's say you want Node to run your file App.js .

1. Check whether or not your file exist in the current working directory (the error says it isn't there) with one of the commands:
   ls (bash, shell, powershell) or dir (cmd).

• If your file ( App.js ) is listed on the output of the above command, then check the spelling and make sure the case exactly matches what you provided to node . That is you command must be node App or node App.js and not node app.js or node aPP.js ...

• If your file isn't listed (what is the more probable outcome) then go to step 2 .

2. Get the full path of the folder containing your file ( App.js ) from your file explorer.

• On windows, just open the folder containing your file and copy the content of the address bar.
• On Linux, refer to this question .
• On Mac, refer to this other question

3. In your terminal navigate to the above folder with the command
   cd copied_path .

---

4. Check again the content of the path to make sure your command line is opened in the right folder.

---

5. Run node App.js
