Laravel 5.5 install not generating .env file

Question

I have installed laravel 5.4 multiple times. Now I'm trying to install laravel 5.5 using same command And it doesn't work.

composer create-project --prefer-dist laravel/laravel blog dev-develop

It doesn't seem to have any errors on installation, only lot of suggestions. But no key is generated and no .env file is created. When I try to make php artisan key:generate

/public_html/blog/.env): failed to open stream: No such file or directory

Answer 1

Got the same problem days a go, the problem was because composer was not updated, solved it updating composer, you can run:

composer self-update

Or you can download the latest version there, then you can create the project again and the .env file will be automatically created.

Answer 2

I have this version

Composer version @package_branch_alias_version@ (1.0.0-beta2) 2016-03-27 16:00:34

When I run composer self-update I get

 [InvalidArgumentException]
 Command "self-update" is not defined.
