composer会自动创建vendor / autoload.php吗？

Question

I'm trying to get the hang of using composer as a library I've downloaded requires it.

I've run composer and all the dependencies appear to have downloaded, however the autoload file isn't present in vendor. Instead of an autoload there's a few empty folders starting from

vendor/symfony/event-dispatcher/symfony/component

Is there something else I need to do?

During the composer install there was one problem encountered regarding being unable to download a file from

nodeload.github.com/symfony/evendispatcher/zip/SomeRandomString

From this it seems as if autoload.php should be automatically created by the dependency resolve process. You might want to check your software sources deprecation status and update package manager lists if necessary (assuming you running a *nix machine). Perhaps local file permissions, as well, could be causing the write/create process to fail.
