It tells me that I have a library error and I don't know what to do to fix it, according to me I'm using the correct ones. Thanks

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

#define LED_DAY 2
#define LED_EVENING 3
#define LED_NIGHT 4
#define LIGHT_SENSOR_PIN A0

LiquidCrystal_I2C lcd(0x27, 16, 2); // Inicializo LCDi2c 0x27

void setup() {
    pinMode(LED_DAY, OUTPUT);
    pinMode(LED_EVENING, OUTPUT);
    pinMode(LED_NIGHT, OUTPUT);
    lcd.begin();
    lcd.backlight();
}

void loop() {
    int lightLevel = analogRead(LIGHT_SENSOR_PIN);
    String timeOfDay;

    if (lightLevel > 800) { // Daytime threshold
        digitalWrite(LED_DAY, HIGH);
        digitalWrite(LED_EVENING, LOW);
        digitalWrite(LED_NIGHT, LOW);
        timeOfDay = "MaƱana";
    } else if (lightLevel > 400) { // Evening threshold
        digitalWrite(LED_DAY, LOW);
        digitalWrite(LED_EVENING, HIGH);
        digitalWrite(LED_NIGHT, LOW);
        timeOfDay = "Tarde";
    } else { // Nighttime
        digitalWrite(LED_DAY, LOW);
        digitalWrite(LED_EVENING, LOW);
        digitalWrite(LED_NIGHT, HIGH);
        timeOfDay = "Noche";
    }

    lcd.clear();
    lcd.setCursor(0, 0);
    lcd.print("Tiempo del dia:");
    lcd.setCursor(0, 1);
    lcd.print(timeOfDay);
    
    delay(1000); // Update every second
}

I'm sure you'll agree that sharing the complete error message, enclosed with the <CODE/> tool as you've already done with your sketch, would go a long way towards enabling anyone to diagnose what your problem might be. I never paid attention in mind reading class as a child, and apparently neither did anyone else.

Please post the complete error message, using code tags.

We can't help if we don't see ALL the verbose verify output in code tags.

You must use

lcd.init();

instead

lcd.begin();
