In the video showing how to set up your virtual Flask environment (https://www.codecademy.com/paths/build-python-web-apps-flask/tracks/introduction-to-flask/modules/flask-templates-and-forms/videos/flask-environment-setup) at around the 8 minute mark, he runs his app in his virtual flask environment. No matter what I do, i keep getting this error in my terminal when I try to follow along:

(myapp) (base) admin.user@admin-user myapp % flask run
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
Usage: flask run [OPTIONS]

Error: While importing "app", an ImportError was raised:

Traceback (most recent call last):
  File "/Users/admin.user/opt/anaconda3/lib/python3.8/site-packages/flask/cli.py", line 240, in locate_app
    __import__(module_name)
  File "/Users/admin.user/Desktop/Python and HG/Flask Virtual Environment/myapp/app.py", line 1, in <module>
    from flask_wtf import FlaskForm
ModuleNotFoundError: No module named 'flask_wtf'

How do i fix this error?

Did you install the module in a virtualenv or globally? Should be in the virtualenv.

See:

I actually fixed it by doing

pip install flask-wtf

in the first filepath: File “/Users/admin.user/opt/anaconda3/lib/python3.8/site-packages/flask/cli.py”, line 240, in locate_app
import(module_name)

I guess i had an older install of python 3.8 in another locaiton on my computer and i needed to install flask-wtf there as well to get it to work
