@guangrei Thanks for reporting!

It looks like you're using the documentation/examples from the current master version while running the v0.2.0 release. Your above code should work against the current master version and the upcoming v0.3.0 release version (#16) 👍

@clue I ran into the same issue. Might be worth going back to https://github.com/clue/reactphp-shell/blob/4121d5ca2f60322830d547c7fe3c0fcbc65068df/examples/php.php until v0.3.0 release.

For me, I'd prefer to use the new syntax, so I uninstalled current release and installed the dev-master version, but I suppose you wouldn't want to make that the default install instructions in readme.

@t-lock Agree with you. I think it makes sense to do what benefits you the most.

I don't know when v0.3.0 will go live, we're currently involved in a lot of other tasks that need our attention. If you need things to speed up in here, consider supporting the project and we'll take a look ;)
