How to update Composer in Windows 10
PhpComposer PhpPhp Problem Overview
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?
Php Solutions
Solution 1 - Php
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
Solution 2 - Php
Windows 10 update for Composer still works (end of 2020, pre version 2) with:
Follow This below Image:
composer self-update --1 it will be updated from 1.x
composer self-update --2 it will be updated from 2.x and from 1.x
composer self-update --rollback If you need to rollback to your previous version
composer -V For check your composer version
composer self-update:
If you run composer self-update from 1.x, it will warn you that a new stable major version of Composer is available, and you can use composer self-update --2 to migrate to it.
So run composer self-update --2
How easy is it to upgrade?
- Composer 2.0 still supports PHP 5.3 and above, much like Composer 1.x
- composer.lock files are interoperable between versions, so you can upgrade to 2.0 and roll back easily if needed.
- Most commands and arguments remain the same, and largely what you know about Composer remains true in 2.0.
Solution 3 - Php
Windows 10 update for Composer still works (end of 2020, pre version 2) with:
composer self-update
If you need to rollback to your previous version, you can do that with:
composer self-update --rollback
Solution 4 - Php
Try.
php composer.phar self-update
'update' updates your dependencies not composer itself.
Solution 5 - Php
Use
composer self-update --2
By default, the installer and composer self-update will download the latest stable version only.
To programmatically install specific major versions you can use the --1 or --2 flag.
To go back to the previous version:
composer self-update --rollback
To check the current version
composer --version
