ESPAsyncWebServer.h with esp32

I am new to esp32 programming. I wanted to try to make a server.

I tried to use the ESPAsyncWebServer library.

I got this error

In file included from C:\Users\User\Documents\Arduino\server\server.ino:2:0:
Multiple libraries were found for "WiFi.h"
sketch\ESPAsyncWebServer.h:33:22: fatal error: AsyncTCP.h: No such file or directory
Used: C:\Users\User\Documents\ArduinoData\packages\esp32\hardware\esp32\1.0.4\libraries\WiFi

Not used: C:\Program Files\WindowsApps\ArduinoLLC.ArduinoIDE_1.8.33.0_x86__mdqgnx93n4wtt\libraries\WiFi
exit status 1
Error compiling for board ESP32 Wrover Module.

Can someone help me and tell me what is the correct way to install liberals because I have a feeling that I am doing it wrong.

Your compile error says that you are lacking the AsyncTCP library. You can find it here:

You will need to install both libraries ESPAsyncTCP and ESPAsyncWebServer, since the latter is dependant on the first.

You can install them by:

1. Downloading the zip files from github:

2. In your Arduino IDE go to Sketch > Include Library > ZIP-Library and select the libraries you just downloaded.
