I installed composer globally on my Debian server
~$ which composer
/usr/local/bin/composer
It works, gets updated and I used it for three different (Symfony) sites.
~$ composer self-update
You are already using composer version 1.3.3 (stable channel).
However, when I am in the directory of one of the sites, and try to update all dependencies, I get an error (before, this just worked and updated the vendors etc).
~/website-path$ ls composer.*
composer.json composer.lock
~/website-path$ composer update
[ErrorException]
Illegal string offset 'version'
~/website-path$ composer
[ErrorException]
Illegal string offset 'version'
When I rename composer.json, this Error disappears (but the lack of .json file makes this quite useless)
What went wrong here and how can I fix this?
The problem magically went away overnight by upgrading to 1.4.0
~$ composer -V
Composer version 1.4.0 2017-03-08 17:51:24
~/website-path$ composer update

I'm trying to install the latest version of Laravel 8 on the latest version of Homestead. When I run composer install or composer update, installation of symfony/var-dumper always fails:
Installing symfony/var-dumper (v5.2.6): Extracting archive
Install of symfony/var-dumper failed
[ErrorException]
file_get_contents(/home/vagrant/code/vendor/symfony/var-dumper/Resources/bin/var-dump-server):
Failed to open stream: No such file or directory
Despite the error exception, the file /vendor/symfony/var-dumper/Resources/bin/var-dump-server does exist.
Things I've tried:
Deleting the lock file and re-running composer update
Manually specifying specific versions of var-dumper, e.g. composer require symfony/var-dumper:5.2.0
I always get the same errors.
Remove /vendor folder, then run:
composer update -v
This turned out to be a compatibility issue with Composer 2.x. I downgraded to the 1.x channel using composer self-update --1, then ran composer install again, and the installation succeeded.
Composer version 2.2.4 2022-01-08 12:30:42
and
symfony/var-dumper v5.4.3
is working just fine
I am using laravel- 7. Everytime I try to install any package in my cpanel ,the process get killed.
composer require milon/barcode
Using version ^8.0 for milon/barcode
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Killed
after that I tried installing the package in my local machine then replace my server composer.lock file with the local's composer.lock file Then go to the terminal and run composer update.
It worked few days.
But now I am facing the issue again. Now I can't even update my composer also.
When I run composer update command.
The process get killed.
[....#host public_html]$ composer update

It is necessary to do the following:
composer self-update
composer global require "fxp/composer-asset-plugin:*"
But after executing the composer self-update, an error pops up:
The "hirak/prestissimo" plugin was skipped because it requires a Plugin API version ("~1.0.0-alpha10") that does not match your Composer installation ("1.1.0"). You may need to run composer update with the "--no-plugins" option.
My current version of Composer is 1.4.2
For the same reason, the following commands do not work:
composer global require "fxp/composer-asset-plugin:*"
An error pops up:
The "hirak/prestissimo" plugin was skipped because it requires a Plugin API version ("~1.0.0-alpha10") that does not match your Composer installation ("1.1.0"). You may need to run composer update with the "--no-plugins" option.
How to get the required version of the Composer Plugin API?
You just need to update hirak/prestissimo:
composer global update hirak/prestissimo --no-plugins
I am trying to install Laravel/Dusk on a laravel 5.4 application.
The command that I am running is, according to the documentation: https://laravel.com/docs/5.4/dusk
composer require laravel/dusk
The output in terminal:
Using version ^1.0 for laravel/dusk
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
- Installing facebook/webdriver (1.3.0)
Loading from cache
- Installing laravel/dusk (v1.0.10)
Downloading: 100%
Killed
That Killed is what's bothering. So, the package is being added to my composer.json file but no files can be found in vendor/laravel/dusk
I am trying to install this on my webhost and not on my local environment.
Any ideas?
The error is due to your machine on the host running out of memory, like described on this thread: https://github.com/composer/composer/issues/1815
So you may have to increase the performance on your account to be able to run more composer commands from your webhost.
i am installing composer dependencies by 'composer install'.
it download bunch of packages but after swiftmailer it gives me error
[UnexpectedValueException]
'C:\Users\DELL\Downloads\laravel-4\vendor/swiftmailer/swiftmailer/72e34d......54c82f.1' is not a zip archive.
what does it mean?
For me this problem happened due to the order composer was installing the files.
The work around that worked for me was to go into \vendor\composer\autoload_real.php and comment out the following line
require $vendorDir . '/swiftmailer/swiftmailer/lib/swift_required.php';
and then run composer again
Running composer install with the --prefer-source option, fixed this problem for me.
