composer.json and composer.lock and composer install and composer update • composer install • installs everything if .lock file doesn’t exist, writes .lock file. • subsequently, brings everything up to date with what’s in the .lock file. • composer update • brings everything in your .json up to date, and updates the .lock file. • Always run composer install on the server. • Composer sees that .json and .lock match, installs everything. • This can be confusing.
