Resolving ESP8266Wifi.h not found error when compiling Code for NodeMCU

This blog - shows how to resolve an error that is usually found at the beginning session of trying to compile ESP8266 code on the Arduino.

At this point -I'd imagine that you have connected one of the USB cable to the NodeMCU and other end to your laptop ( In my case a Mac OS)

If you tried to compile and Upload a sample code something like

#include <ESP8266WiFi.h>

constchar*ssid ="Name";
constchar*password ="Password";

; //
WiFiServerserver(80);

voidsetup() {
 Serial.begin(115200);
 delay(10);
...

and got an error that the ESP8266WiFi.h - was not found , then follow instructions as shown in this link:

In my case - I had to copy, and unzip master.zip it in Users/shashikiran/Documents/Arduino/librariesfolder
and then compile the code.
Without which I was getting the "ESP8266WiFi.h not found in this Arduino workbench window.
