My composer.json file in ~/.composer:
{
"require": {
"laravel/installer": "^1.3"
}
}
I am using Laravel 5.2.

Answer 1

I've found the solution to this problem.
This problem exists because Laravel 5.2 need symfony/process 2.8.* | 3.0.* and Envoy need symfony/process 2.4.* and when you are using higher symfony/process version, It faces some trouble in order to realize the difference of versions.
Solution:
Open composer.json file in ~/.composer:
$ vi ~/.composer/composer.json
It should look like this:
{
"require": {
"laravel/installer": "^1.3"
}
}
Change it to:
{
"require": {
"laravel/envoy": "~1.0",
"laravel/installer": "^1.3"
}
}
Now use:
$ composer global require "laravel/envoy=~1.0"

Don't forget to make your composer alias available from your $PATH
composer global require laravel/envoy
You may need to (if not already) add your global composer directory to your $PATH
Add this line into your ~/.bash_profile or ~/.bashrc.
export PATH="$HOME/.composer/vendor/bin:$PATH"
