[FIXED] How to update Composer in Windows 10

Issue

I am using Composer for my PHP project. I am new to Composer. Now when I update my dependencies using composer update command, it is saying that my Composer version is too old and ask me to update. So I tried as below. But all failed.

My composer.phar file is in C:/ProgramData/ComposerSetup/bin/composer.phar

I opened terminal and tried

composer.phar update

php composer.phar update

composer C:/ProgramData/ComposerSetup/bin/composer.phar update

php composer C:/ProgramData/ComposerSetup/bin/composer.phar update

When I run composer-self-update, error as in screenshot.

All command failed. I am using XAMPP. There is no composer.phar file in xampp/php folder as well. How can I update Composer in Windows 10?

Solution

Try

composer self-update

If this doesn't work check your PATH variable, if it's not there try searching composer.bat in windows and add it to your PATH variable. Normally, its in following path.

C:\ProgramData\ComposerSetup\bin
