Laravel Homestead Mongo install causing PHP error undefined symbol: php_json_serializable_ce in Unknown on line 0

Question

PHP Warning: PHP Startup: Unable to load dynamic library \'/usr/lib/php/20151012/mongodb.so\' - /usr/lib/php/20151012/mongodb.so: undefined symbol: php_json_

Answer 1

I had the same problem, I solved it by reverting to an older PECL mongodb version (1.1.9). There was an update to version 1.2.0 on November 29th, which is why the mongo-php-library also got updated to version 1.1.0.

Here is what I did:

sudo pecl uninstall mongodb
sudo pecl install mongodb-1.1.9
composer update

The pecl commands will show the same warning, but the installation was successfully completed.

I hope that the mongo-php-library will be fixed soon, so we're not stuck using an older PECL extension.
