Upgrade to Composer 2.x

[pramanikriju]

I have laragon installed, but I have been unable to upgrade to the 2.x version.
What are the steps that I should follow for Laragon on windows to upgrade my composer?

@pramanikriju : What the steps did you do to upgrade composer?

[pramanikriju]

First I tried the official method to run the windows setup file, but laragon has it's own composer in the 'bin' directory.
So I replaced the composer.phar file there and followed the steps here
Then I restarted laragon, but composer -V still gives me 1.x

The upgrade process is based on getcomposer.org/download/

You first need to change your directory to C:\laragon\bin\composer Or in explorer navigate to C:\laragon\bin\composer and open Terminal

cd C:\laragon\bin\composer

Run composer -V to get the current version (e.g.):

C:\laragon\bin\composer
λ composer -V
Composer version 1.10.7 2020-06-03 10:03:56

Then follow the steps from getcomposer.org/download/

Note: There steps are for composer v2.0.3, the hash_file will be different for newer versions! Check the link above for the latest version.

C:\laragon\bin\composer
λ php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

C:\laragon\bin\composer
λ php -r "if (hash_file('sha384', 'composer-setup.php') === 'c31c1e292ad7be5f49291169c0ac8f683499edddcfd4e42232982d0fd193004208a58ff6f353fde0012d35fdd72bc394') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
Installer verified

C:\laragon\bin\composer
λ php composer-setup.php
All settings correct for using Composer
Downloading...

Composer (version 2.0.3) successfully installed to: C:\laragon\bin\composer\composer.phar
Use it: php composer.phar


C:\laragon\bin\composer
λ php -r "unlink('composer-setup.php');"

Check the version of composer by running composer -V

C:\laragon\bin\composer
λ composer -V
The "hirak/prestissimo" plugin was skipped because it requires a Plugin API version ("^1.0.0") that does not match your Composer installation ("2.0.0"). You may need to run composer update with the "--no-plugins" option.

If you have a message about "hirak/prestissimo" plugin, like me, you can uninstall it: composer global remove hirak/prestissimo (e.g.):

λ composer global remove hirak/prestissimo

So the steps work to upgrade my composer version to 2.x

But then, when I switch directories to any of my existing projects under 'www' and type
C:\laragon\www\project (master) λ composer -V Composer 1.10.8 2020-06-24 21:23:30

Whereas the composer folder in bin is updated to 2.x
C:\laragon\bin\composer λ composer -V Composer version 2.0.4 2020-10-30 22:39:11

So how will I know which composer file is being used in the project directory and how do I update those specifically?

@pramanikriju My guess is you have Composer installed globally.

• See this OS question
  • Change COMPOSER_HOME to c:\laragon\bin\composer.
• You can also check control panel > programs and remove Composer.
• Finally check you have added Laragon to PATH.
  • Menu > Tools > Path > Manage Path, then if required Add Lagaon to Path.
  • Log off and back on after changing the Path.

I have successfully upgraded my composer to 2.x using these methods

• Find where your composer file is which composer

• For me, it was in
  /c/Users/USERNAME/AppData/Roaming/Composer/vendor/bin/composer

• Open a terminal in that directory

• follow the steps here - Installastion Steps

• composer -V should now return 2.x

composer selfupdate does the trick .-.
