Laravel 5.2项目工匠错误

I have Laravel 5.2 project and when I'm trying to install it to my home computer, I have some troubles with it. All steps what I do are next below:

First I clone project by command:

git clone https://bitbucket.org/.../...

Then I try to install project requires by command

composer install

and have this error

[PDOException]
SQLSTATE[HY000] [1045] Access denied for user 'forge'@'localhost' (using password: NO)

After creating and configuring .env file a have next error

[Illuminate\Database\QueryException]
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'test_db.tasks' doesn't exist (SQL: select * from `tasks` where `tasks`.`deleted_at` is null)

[PDOException]
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'test_db.tasks' doesn't exist

And now when I try to make any php artisan command I have this error.

I found at Laracasts that I have to comment all my own ServiceProvider but that did not solve my problem.
