Composer not installing

Question

I have installed windows 10 on my pc and when I installing composer it shows:

The PHP exe file you specified did not run correctly: D:\\Xampp\\php\\php.exe

The php.ini used by your command-line PHP is: D:\\Xampp\\php\\php.ini

A setting in your php.ini could be causing the problem: Either the ' extension_dir ' value is incorrect or the dll does not exist.

Program Output:

Answer 1

May I know do you run it by administrator powershell during the installation,

if yes please check those extensions whether exist or not,

and does install correctly : https://getcomposer.org/doc/00-intro.md#using-the-installer

C:\bin>echo @php "%~dp0composer.phar" %*>composer.bat

The @php does it point to your php of xampp? You can check .
