无法在Codeship上安装Blackfire PHP

Question

I try to deploy my PHP application to Heroku through Codeship. Heroku requires to add ext-blackfire to my composer.json and it results in a crash on Codeship at composer install.

The requested PHP extension ext-blackfire ~1.18 is missing from your system. 
Install or enable PHP's blackfire extension.

How can I install Blackfire extension on Codeship?

Answer 1

You should be able to install your dependencies through composer install --ignore-platform-reqs, which ignores any missing extensions. See the docs (https://getcomposer.org/doc/03-cli.md) for more details.
