无法在虚拟环境中导入'flask_wtf'和'wtforms'，即使我已经安装了它们？

Question

So I'm running a virtual python environment and I was learning flask. Everything was going good until I got to learning about forms. I pip installed Flask-WTF in the console (just as I had done with Flask) except when I went to type my code I saw that neither flask_wtf or wtforms could be imported. Here's my code:

from flask_wtf import FlaskForm
from wtforms import BooleanField, PasswordField, StringField, SubmitField
from wtforms.validators import DataRequired

class LoginForm(FlaskForm):
    username = StringField('Username', validators=[DataRequired()])
    password = PasswordField('Password', validators=[DataRequired()])
    remember_me = BooleanField('Remember Me')
    submit = SubmitField('Sign In')

I get errors on lines 1 - 3 for all of the imports. Here's my FlaskProject (top-level) directory:

Flask Project Top-Level Directory

Here are all the modules I have installed:

Flask Project Installed Modules

I'm really not sure what's causing these errors.

EDIT: I also think it's worth noting that I'm not getting errors when importing other modules such as flask. In case anyone asks, here are the versions of the modules I currently have installed:

Installed Modules w/ Versions

EDIT2: I'm running Python 3.7

EDIT3: These are the only two things I can't seem to import

EDIT4: I've actually solved this and I have no idea why but VSCode was marking these items as unable to import when they were, in fact, importing perfectly fine. Anyways, thanks for the help everyone!

Answer 1

Maybe you can't see these modules because you've installed them from another virtual environment. Can you tell what is the output when you execute the command pip list? If there are no modules flask_wtf and wtfforms, you have to activate your virtualenv where are those modules installed. Activate virtualenv using the command:

Windows - source venv/scripts/activate
Linux - source venv/bin/activate

And after that, if you don't have any of these modules already installed, install them using command pip install name_of_module.

VSCode was marking the imports as an import-error when there was no actual error. Very weird but everything imported perfectly fine.
