Little FS not declared in this scope (ESP 32 - PlatformIO)

[MainWire]

The problem :
FS.h library isn't found, or parts of the FS library aren't founds when trying to compile.

IDE : PlatformIO
Version : v2.4.79
Board : esp32 DOIT Devkit-v1
TFT Driver : ILI9341_DRIVER
Interface : SPI

To Reproduce the problem :
Compiling a cpp sketch with TFT library on Visual Studio code using PlatformIO

My Workspace :

• Libraries tree :
  |-- TFT_eSPI @ 2.5.23
  |---|-- SPI @ 2.0.0
  |---|-- SPIFFS @ 2.0.0
  |---|-- LittleFS @ 2.0.0
  |-- TFT_eWidget @ 0.0.6
  |---|-- LittleFS @ 2.0.0
  |---|-- TFT_eSPI @ 2.5.23
  |---|---|-- SPI @ 2.0.0
  |---|---|-- SPIFFS @ 2.0.0
  |---|---|-- LittleFS @ 2.0.0
  |-- WiFi @ 2.0.0

My cpp file :

#include <Arduino.h>
#include <TFT_eSPI.h>  
#include <TFT_eWidget.h>
#include <FS.h>  //<---File not found, using either `#include <FS.h>` or `#include <LittleFS.h>`
#include <ESP.h>
#include <WiFi.h>

My platform.ini file :

[env:esp32doit-devkit-v1]
platform = espressif32
board = esp32doit-devkit-v1
framework = arduino
lib_deps = 
	bodmer/TFT_eSPI@^2.5.23
	bodmer/TFT_eWidget@^0.0.6

The issue started with that one : khoih-prog/ESPAsync_WiFiManager#96
At the begeninning the problem I had was the file object that wasn't declared. Deleting the library inside the platform.ini file didn't help, I now struggle with two problems : I either have a problem where FS.h library isn't found, or parts of the FS library (File object) that aren't founds when trying to compile.
I couldn't get past the problem as described, despite those existing issues.

Does anyone have an idea to bypass that problem ?
Thanks in advance

The first error is:

C:/Users/wawe/.platformio/packages/framework-arduinoespressif32/libraries/LittleFS/src/LittleFS.cpp:17:10: fatal error: vfs_api.h: No such file or directory

So there is a file in the board package that is not being found. I suspect this is the root cause.

Update the board package or roll back to an earlier version. Since this is an environment problem rather than with the TFT_eSPI library I will move it to discussions. May be worth posting on Espressif or PlatformIO forums.

Hi,

Thanks for your answer, I finally managed to make it work yesterday, by uninstalling and resetting everything.
I cannot understand what was wrong but it is fixed, and working.

Sorry if it was the wrong topic :/ Will pay attention next time !
