Errors installing Composer on macOS (JIT compilation failed)

php macos composer-php jit php-7.3

Solution 1

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

Solution 2

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

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

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

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

When I run composer --version in the macOS terminal, I get the following errors.

Is that explicitly telling composer to simply run on PHP 5.x?

@Umbrella Exactly. Its setting up a path for execution of composer.

Downgrading PHP also works, but is quite extreme. Perhaps invoking with -d pcre.jit=0 or adding same to a configuration file would allow you to continue using version 7 without the trouble.

What happens when something you try to install via composer has php 7 as a requirement? Not to mention the fact that you're keeping a PHP version on your computer that is officially End-of-life.

this will disable it completely. to just disable it for composer, see bishop's answer stackoverflow.com/a/53772696/4233593

I did this on the loaded php.ini but PCRE JIT is still enabled.

This was a very clear step by step explanation. Thank you.
