Magento 2 EE: Running composer update is giving error

Question

I am trying to run composer update and want to push the changes to magento cloud but is giving the following error:

Problem 1

• magento/product-enterprise-edition 2.3.4 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.
• magento/product-enterprise-edition 2.3.4 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.
• Installation request for magento/product-enterprise-edition 2.3.4 -> satisfiable by magento/product-enterprise-edition[2.3.4].

Maybe because it is conflicting with my local PHP environment? I am running the command outside the docker container. Is it necessary to run the commands inside a docker container?

Answer 1

Composer must be run using PHP that is used by your Magento instance. If you use a Docker setup, you need to run it inside Docker container (via 'docker exec' command, see: https://docs.docker.com/engine/reference/commandline/exec/).

Answer 2

run

sudo apt install php7.x-bcmath

change x with your PHP version
