I have downloaded a project from github and tried npm install in my application but I get this error result:

> [email protected] install C:\Users\Admin\Desktop\New folder\flow\node_modules\node-sass
> node scripts/install.js

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.9.0/win32-x64-72_binding.node
Cannot download "https://github.com/sass/node-sass/releases/download/v4.9.0/win32-x64-72_binding.node":

HTTP error 404 Not Found

Hint: If github.com is not accessible in your location
      try setting a proxy via HTTP_PROXY, e.g.

      export HTTP_PROXY=http://example.com:1234

or configure npm proxy via

      npm config set proxy http://example.com:8080

As I am a new Angular learner I can't understand the error message? I could run the program in other laptop in my home but can't in my office computer! Please help me know what is the problem and how can I fix it?

EDIT: I also tried npm install --global windows-build-tools but I got this result and seems it's stopped working:

Try to install this module in Windows. To install node-sass on windows 10, you probably need to install windows-build-tools

https://github.com/felixrieseberg/windows-build-tools

Run following command in terminal

npm install --global windows-build-tools

And try npm install

You probably need to have visual studio installed and relevant modules such as windows development tools, C++ compile tools on the machine, I think.

@Hasani, As you mentioned you can't run the project on the office computer is because your office computer is under the proxy and You should set up the proxy to access the NPM's

Your Error message which says to configure the proxy is here

HTTP error 404 Not Found

Hint: If github.com is not accessible in your location
      try setting a proxy via HTTP_PROXY, e.g.

      export HTTP_PROXY=http://example.com:1234

or configure npm proxy via

      npm config set proxy http://example.com:8080

This is how you can do.

For HTTP

npm config set proxy http://proxy_host:port

For HTTPS

use the https proxy address if there is one

npm config set https-proxy https://proxy.company.com:8080

If you have password and user name to be entered you can try this one 

npm config set https-proxy http://<username>:<password>@proxy<COMPANYDOMAIN.COM>.com:8080

I can't understand what is the proxy?
When I connect to wi-fi at the office, it goes automatically to this page: hotspot.sbu.ac.ir/login then there is a form that I must enter my user and pass then the internet will work until I disconected. I also I can open github.com in my browser without any problems.
you are allowed to access this git hub from the browser but not using command line when you behind the proxy. So please do the configuration and follow the steps properly and you can make npm and flutter commands works fine in the office computer
