Help with the installation please

hello, maybe this helps

Modify your ionic.cmd file in C:\Users\AppData\Roaming\npm by adding --max_old_space_size. I set mine to 8096.

@if EXIST "%~dp0\node.exe" (
"%~dp0\node.exe" --max_old_space_size=8048 "%~dp0\node_modules\ionic\bin\ionic" %*
) ELSE (
@SETLOCAL
@set PATHEXT=%PATHEXT:;.JS;=;%
node --max_old_space_size=8048 "%~dp0\node_modules\ionic\bin\ionic" %*
)
