When installing latest MongoDB library, following error is shown

pi@raspberrypi:~ $ composer require mongodb/mongodb
Using version ^1.2 for mongodb/mongodb
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for mongodb/mongodb ^1.2 -> satisfiable by mongodb/mongodb[1.2.0].
    - mongodb/mongodb 1.2.0 requires ext-mongodb ^1.3.0 -> the requested PHP extension mongodb is missing from your system.

  To enable extensions, verify that they are enabled in those .ini files:
    - /etc/php/7.0/cli/php.ini

Installation failed, reverting ./composer.json to its original content.
pi@raspberrypi:~ $

I have installed php developer library, installed pecl MongoDB dependencies and also updated php.ini file.

Steps I have use from the beginning.

  • sudo apt-get update
  • sudo apt-get upgrade
  • sudo apt-get install apache2 php mysql-server phpmyadmin mongodb-server this step installed MongoDB 2.4. MongoDB 3.x doesn't seem to work with ARM Chipset.
  • sudo apt-get install php7.0-dev (used this to remove phpize error)
  • sudo pecl install mongodb
  • Added extension=mongodb.so in php.ini file
  • composer require MongoDB/MongoDB

  • Could you edit to include the steps you used to install the compiled module for MongoDB and the output of php -i? Thanks. – Aurora0001 Jan 18 '18 at 15:20
  • please take a look @Aurora0001, I have added the details. – Awatansa Vishwakarma Jan 18 '18 at 20:57
  • Thank you; could you include the output of php -i too? – Aurora0001 Jan 18 '18 at 20:58
  • It is working now, I don't know why, but first time editing php.ini file saved successfully, but not in actual. A reboot made it clear and solved the issue. Thanks :-) – Awatansa Vishwakarma Jan 18 '18 at 21:20

The problem was with php.ini file, on 1st try, adding extension=mongodb.so and saving setting didn't save despite showing the change in the file on opening.

After a reboot of the system, I edited the file again and this time, it worked. I don't know why such thing happened and didn't save but it works fine now.
