[Fixed]-Django1.8.11 migrate installed_apps error

Your database user does not have the neccessary access rights. The error message

"INDEX command denied to user 'yy'@'localhost' for table 'django_session'"

indicates this.

For development you might want to add full access using this statement

GRANT ALL PRIVILEGES ON first.* TO 'yy'@'localhost' IDENTIFIED BY '123456';
