[python] WTForms : 이메일 유효성 검사 지원을 위해 ’email_validator’설치

양식 유효성 검사를 위해 다음 코드를 실행할 때 예외가 발생합니다.

File "/Users/homeduvvuri/Documents/Learning/PartyGoUdemy/PartGo/user/forms.py", line 11, in BaseUserForm
    email = EmailField('Email', [validators.DataRequired(), validators.Email()])
File "/Users/homeduvvuri/Documents/Learning/PartyGoUdemy/PartGo/partgo-env/lib/python3.7/site-packages/wtforms/validators.py", line 332, in __init__
    raise Exception("Install 'email_validator' for email validation support.")
Exception: Install 'email_validator' for email validation support.

어디에서나 VM에서 완벽하게 실행됩니다. 로컬 컴퓨터에 없습니다.
