Why I cannot run npm run dev on a centos7?

I have a problem installing my app on a new server, I come from centos6 to centos7.
When I am installing a Laravel app that works perfectly on centos6 it goes right except when I run npm run dev

I have been searching for an answer for hours but nothing works.
I tried to delete node_modules and package-lock and reinstall, but also didn't work.

Ok the problem might be permission as dimitri says. I just go to node_modules/webpack/bin/webpack.js and change the permission to 777
I dont know if this is recomended but at least works

Can not import reactjs

I'm trying to import react, I wrote the following code:
import React from "react";
but when I write npm start in the terminal it shows me these errors:

The error is Error: listen EADDRINUSE 127.0.0.1:8080 which means there already is something that uses port 8080 on your machine, try changing the port webpack starts the dev server

solution 1: if your are beginner - just restart your PC.
solution 2: open task manager and kill all node instances.
alternatively you check if there is some other react app already running on port 8080 so you have to stop it
OR
you have to change your current app port to some other port.

i had this error when i run npm start frontend(angularjs)and in the symfony is run correctly can someone have a idea how can i solve.

Another process is already listening on port 8001. You are either trying to start your server twice, or there is another server/application which uses that port. The solution is to change the port or kill the process which listens on the same port.

How to build VSCode on Windows?

I am trying to build https://github.com/Microsoft/vscode from the source, but I am not sure exactly what to do. When I ran scripts\npm.bat install, it completed successfully. Then I ran scripts\code.bat and a stranger window showed up. It is it the compiled version? It did not seem to work correctly.
How can I create full build? The page:
https://github.com/Microsoft/vscode/wiki/How-to-Contribute#build-and-run-from-source
Does not offered how to create an executable from the source. When I run scripts\npm.bat install what should happen? For now I only see it create the folder out/out-build within some javascript files, as showed bellow. What are those files and what I do with them?
Later I tried to ran the scripts\code.bat and created an executable similar in size to the stable version on the folder .build\electron:
But when I ran npm run watch, this error is throw:

I found the other question:
How to build release vscode version
But I could not figure it out correctly how to build it. Forehand I figured out the following steps to setup the environment:
Install NodeJS and npm. See
the tutorial How to Install Node.js® and NPM on
Windows
Run this command npm install --global --production windows-build-tools from cmd line as
Administrator. See npm install error - MSB3428: Could not load the Visual C++ component
“VCBuild.exe”
Install gulp. See gulpjs/gulp#Getting
Started
Steps to Reproduce
git clone https://github.com/Microsoft/vscode
cd vscode
scripts\npm.bat install
npm run watch
Outputs: F:\vscode>npm run watch
File npm-debug.log:
1) When I ran the command scripts\npm.bat install for the first time, this was the output:

And the following window showed up:

The problem seems to be the outdated version 6.11.0 of nodejs used. From the issue: Failed at the code-oss-dev#1.15.0 watch script 'gulp watch --max_old_space_size=4096' on the VSCode issue tracker, we may follow the steps:
Install Node 7.9.0
git clean -xfd .
git pull
.\scripts\npm.bat install
Then, if there are no errors:
npm run watch
Run it until it tells you compilation succeeded. Then:
.\scripts\code.bat

When I try to follow the instructions, I get:

Appreciate your attention.

If you type in:
cat /etc/dogtag
you will get a readout. This readout tells you what version of Linux you have on your machine. If you go to http://elinux.org/Beagleboard:BeagleBoneBlack_Debian, the images are updated regularly for the BBB and BBG boards.
Try to update your image and then upgrade to the newer version of socket.io.

P.S. If this does not work, please let me know.
