This is a known PHP 7.3 bug, which has already been fixed.

As a temporary workaround, edit your php.ini file (in my case: vi /usr/local/etc/php/7.3/php.ini), disable PHP PCRE JIT compilation by changing:

;pcre.jit=1

pcre.jit=0

Php – Composer install/update failing

Packagist is having an outage. https://twitter.com/PrincipeBorodin/status/342655643603324929

About all you can do is try to contact @packagist or the contact us page on packagist.org

I'm seeing exactly the same thing on one of my projects. If you go to https://packagist.org/packages/base-reality/php-to-javascript you can see the latest version is 0.1.17

But the doing:

composer show base-reality/php-to-javascript

gives

versions : dev-master, * 0.1.16, 0.1.15, 0.1.14, 0.1.13, 0.1.12, 0.1.11, 0.1.10, 0.1.9, 0.1.8, 0.1.7, 0.1.6, 0.1.5, 0.1.4, 0.1.3, 0.1.2, 0.1.1, 0.1.0, 0.0.9, 0.0.8, 0.0.7, 0.0.6, 0.0.5, 0.0.4, 0.0.3, 0.0.2, 0.0.1

i.e. the 0.1.17 version isn't available through composer.

Update

It is now fixed now https://twitter.com/packagist/status/342710331547729920

Php – Composer require runs out of memory. PHP Fatal error: Allowed memory size of 1610612736 bytes exhausted

To get the current memory_limit value, run:

php -r "echo ini_get('memory_limit').PHP_EOL;"

Try increasing the limit in your php.ini file (ex. /etc/php5/cli/php.ini for Debian-like systems):

; Use -1 for unlimited or define an explicit value like 2G
memory_limit = -1

Or, you can increase the limit with a command-line argument:

php -d memory_limit=-1 composer.phar require hwi/oauth-bundle php-http/guzzle6-adapter php-http/httplug-bundle

To get loaded php.ini files location try:

php --ini

Another quick solution:

php composer.phar COMPOSER_MEMORY_LIMIT=-1 require hwi/oauth-bundle php-http/guzzle6-adapter php-http/httplug-bundle

Or just:

COMPOSER_MEMORY_LIMIT=-1 composer require hwi/oauth-bundle php-http/guzzle6-adapter php-http/httplug-bundle
