Seven Segment Display programing problem

Hi I need to display temperature and humidity on 7 segments by library named sevenSegmentDisplay,
I have a problem in one programming Lines (colored in red) He say
'sevenSegmentsDisplays' does not name a type , I don't understand it so i need help.

// Libraries
#include <DHT.h>
#include <sevenSegmentDisplay.h>

// Setup Sensor.
#define DHTPIN 2 // Temperature Sense pin
#define DHTTYPE DHT11 // DHT 11
DHT dht(DHTPIN, DHTTYPE); // Initialize DHT Sensor

// Variables
float hum; // Humidity
float temp; // Temperature

// Variable to store current time.
unsigned long previousMillis = 0;

// Set interval to read temperature.
const long interval = 2000;

// Configure a 2-Digit 7-Segment Display.
int segments[7] = {3, 4, 7, 6, 5, 10, 8}; // Display segments (a,b,c,d,e,f,g)
int displays[2] = {12, 11}; // Display digits (00 - 99)
int type = COMMON_ANODE; // Type

SevenSegmentDisplay sevenSegmentDisplay(
segments[0],
segments[1],
segments[2],
segments[3],
segments[4],
segments[5],
segments[6],
displays[0],
displays[1],
type
);

void setup()
{
Serial.begin(9600);
dht.begin();
sevenSegmentDisplay.begin();
}

void loop()
{
// Get current time in milliseconds.
unsigned long currentMillis = millis();

// Read temperature every 2 seconds.
if (currentMillis - previousMillis >= interval) {
// Save the last time we've read the temperature.
previousMillis = currentMillis;

// Read data and store it to variables hum and temp.
// hum = dht.readHumidity();
temp = dht.readTemperature();
}

// Display temperature.
sevenSegmentDisplay.display(temp);
}

Where did you find that library? There seem to be multiple libraries of that name. Have you gotten the examples that come with the library that you have to work?

The problem there is no examples

Here's library :
