Your requirements could not be resolved to an installable set of packages. Problem 1 - chrome-php/wrench[v1.5.0, ..., 1.6.x-dev] require ext-sockets * -> it is missing from your system. Install or enable PHP's sockets extension. - row-bloom/row-bloom dev-main requires chrome-php/chrome ^1.9 -> satisfiable by chrome-php/chrome[v1.9.0, v1.9.1, 1.9.x-dev, 1.10.x-dev]. - chrome-php/chrome[v1.9.0, ..., 1.10.x-dev] require chrome-php/wrench ^1.5 -> satisfiable by chrome-php/wrench[v1.5.0, 1.5.x-dev, 1.6.x-dev]. - Root composer.json requires row-bloom/row-bloom dev-main -> satisfiable by row-bloom/row-bloom[dev-main]. To enable extensions, verify that they are enabled in your .ini files: - C:\tools\php\php.ini You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode. Alternatively, you can run Composer with `--ignore-platform-req=ext-sockets` to temporarily ignore these required extensions.
