flask migrate is missing from requirements.txt

[ShalbafZadeh]

after installing packages from requirements file when i try to run app i get this error:

(test) [reza:~/Code/python/EasyCRM]$ python manage.py runserver          (master) 
Traceback (most recent call last):
  File "manage.py", line 3, in <module>
    from flask_migrate import Migrate, MigrateCommand
ImportError: No module named flask_migrate

requirements.txt
it could be solved by adding flask_migrate in
