I am newly converting from Arduino IDE and Visual Studio using the Microsoft Arduino extension working with .ino files. I installed the PlatformIo IDE extension (using all users in advanced install experience). I create a new project - selecting EspressIf 32 development board and arduino for the framework. I then compile using PIO RUN and things compile fine. I then go to add a single library - Adafruit BusIO for an example by adding it to my platformio.ini file. I then try to compile again with PIO RUN and it blows up with a missing header file:
#include <Wire.h>
^~~~~~~~
compilation terminated.
In file included from .pio/libdeps/esp32dev/Adafruit BusIO/Adafruit_I2CDevice.cpp:1:
.pio/libdeps/esp32dev/Adafruit BusIO/Adafruit_I2CDevice.h:5:10: fatal error: Wire.h: No such file or directory
The Wire.h file is a standard Arduino library function that should not require any additional dependency. When I look at the dependencies I don’t see anything missing:

Here is my platformio.ini file:
[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
lib_deps =
Adafruit BusIO
It feels like the header include system is messed up. Is that because I had the previous Microsoft Arduino extension installed? What can I look for to ensure it knows where to find that header?
Or is this an issue of something picking up an executable from another folder? Here is my environment path:
Path=C:\Program Files\Python311\Scripts\;C:\Program Files\Python311\;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\WINDOWS\System32\OpenSSH\;C:\Program Files\Git\cmd;C:\Users\shanl\AppData\Local\Microsoft\WindowsApps;C:\Users\shanl\AppData\Local\Programs\Microsoft VS Code\bin;C:\Users\shanl**\.vscode\extensions\vsciot-vscode.vscode-arduino-0.5.0-win32-x64\assets\platform\win32-x64\arduino-cli**;
What other steps can I take to diagnose this?
