Resolved Unable to initialize custom php module v8js

[nisamudeen97]

Hi,

I am trying to enable v8js module for php 7.1 in plesk. I need this for installing dreamfactory. I followed the below doc as base and installed module in the server.

v8js - DreamFactory

Meanwhile i am getting the below information in php cli. Is there any solution for the same ?

PHP Warning:  PHP Startup: v8js: Unable to initialize module

Module compiled with module API=20151012

PHP    compiled with module API=20160303

These options need to match

 in Unknown on line 0

This means the extension was compiled with a different version of PHP than the one you're trying to use. In step 3 of the instructions you linked to, when you run "phpize", you need to choose the one for the version of PHP you'll be using. They're located in /opt/plesk/php/<version>/phpize ("<version>" being 7.0, 7.1 or 7.2 - though your setup may vary depending on which versions of PHP you have installed).

You need to start from something like:

# apt-get install plesk-php71-dev libv8-dev
# /opt/plesk/php/7.1/bin/pecl install v8js
...

Have you installed libv8-dev?

Hi,

Yes, I do.

root@:/opt/plesk/php/7.1/etc/php.d# apt-get install libv8-dev

libv8-dev is already the newest version (3.14.5.8-5ubuntu2).

I suppose that you need to compile v8js according to phpv8/v8js anв then use path /opt/v8 for the question:

Please provide the installation prefix of libv8 [autodetect] :

when you run

# /opt/plesk/php/7.1/bin/pecl install v8js
