Php Solutions
Solution 1 - Php
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
to
pcre.jit=0
Solution 2 - Php
I solved this by disabling the PCRE jit compilation.
I suppose you installed php 7.3 through homebrew.
If so, create a zzz-myphp.ini in /usr/local/etc/php/7.3/conf.d with the following content:
; My php.ini settings
; Fix for PCRE "JIT compilation failed" error
[Pcre]
pcre.jit=0
Solution 3 - Php
Other answers suggest disabling PCRE JIT via a configuration file. That works, but caveat: this disables PCRE JIT for all engine invocations that use those INI files. You therefore won't be getting JIT improvement for a potentially wider swath of functionality, which may not be desired.
You can disable JIT for composer only via:
php -d pcre.jit=0 composer.phar ...
Solution 4 - Php
In PHP 7.1.24 there is no 'pcre.jit' in php.ini file so you have to set
memory_limit:128M (if you increase this).
Solution 5 - Php
It work for me by follow steps:
- Open you Terminal and run php --ini
- Open file php.ini in the path "Loaded Configuration File: /usr/local/php5/lib/php.ini" https://prnt.sc/p9tspy
- Find pcre.jit and change ;pcre.jit=1 to pcre.jit=0
Solution 6 - Php
Thanks for the answers.. I solved it by command composer.phar and then export path. Example:
$composer.phar
$export PATH=/usr/local/php5/bin:$PATH
$composer.phar --version
Solution 7 - Php
I got the same error. I installed MAMP 5.4 on my Mac OS 10.11.6 using PHP 7.3.7 and installed Composer. It seemed to work but as soon as I attempted to install Yii2 or even check the version, it gave me the error...
$composer.phar --version
Fatal error: Uncaught ErrorException: preg_match_all(): JIT compilation failed: no more memory in phar:///Users/kristin/Sites/htdocs/composer.phar/vendor/symfony/console/Formatter/OutputFormatter.php:137
Increasing the memory_limit in php.ini from 128M to anything did NOT solve the issue and pcre.jit=1 was commented out so turning it off didn't do anything either.
Here is what worked:
I simply changed the export path to the previous version's directory (without actually downgrading in MAMP's preferences) and it worked!
$export PATH=/Applications/MAMP/bin/php/php7.2.20/bin:$PATH
$composer.phar --version
Composer version 1.9.0 2019-08-02 20:55:32
If anyone can explain why this worked, I'd appreciate knowing. Cheers.
Solution 8 - Php
This works for me -
alias composer='php -d pcre.jit=0 /usr/local/bin/composer'
It's does not require and older version of PHP and is specific to composer. To persist across shell closure edit and add to ~/.bash_profile.
