If none of the solutions work for you  the handling the post-autoload-dump event returned with error code 1 error can also be caused by using Composer 2 instead of Composer 1  That can happen when you run the install command manually in something like a Dockerfile  and it installs newest  Just modify your command to install the last 1 x x stable version with the --1 option  curl -sS https   getcomposer org installer   php -- --install-dir  usr local bin --filename composer --1  Or  specify a certain version with --version x x x  curl -sS https   getcomposer org installer   php -- --install-dir  usr local bin --filename composer --version 1 10 17  It might be good to also delete your vendor directory and composer lock file so that nothing stale interferes with the version downgrade  before calling composer install as usual
