Could not open input file: ./vendor/bin/protobuf

[xiaochuanyu]

I'm trying to generate php code for a particular .proto file following instructions from the README.
I did the following in an empty directory with addressbook.proto :

brew install php composer protoc
composer require "protobuf-php/protobuf-plugin
php ./vendor/bin/protobuf --include-descriptors -i . -o ./src/ ./addressbook.proto

I get error saying:

Could not open input file: ./vendor/bin/protobuf

In vendor/ there is only the following folders:

autoload.php  composer/  protobuf-php/

What am I missing?

Info:

$ protoc --version
libprotoc 3.2.0
$ composer --version
Composer version 1.3.2 2017-01-27 18:23:41
$ php --version

Same here, I'm missing the vendor/bin directory. I followed the documentation but something is wrong.

In fact this is a documentation problem in https://github.com/protobuf-php/protobuf

There are two different projects: protobuf, and protobuf-plugin. Both must be installed to follow the instructions in the README.

See https://github.com/protobuf-php/protobuf-plugin#composer-install for instructions
