Missing dependencies with tutorial installation

[matt-sd-watson]

I followed the tutorial installation steps here: https://stlearn.readthedocs.io/en/latest/installation.html

but encounter missing dependencies from pip on stlearn launch:

File "/home/admin/anaconda3/envs/stlearn/lib/python3.10/site-packages/stlearn/app/source/forms/forms.py", line 7, in <module>
    import wtforms
ModuleNotFoundError: No module named 'wtforms'

File "/home/admin/anaconda3/envs/stlearn/lib/python3.10/site-packages/stlearn/app/source/forms/views.py", line 16, in <module>
    from stlearn.app.source.forms import forms
  File "/home/admin/anaconda3/envs/stlearn/lib/python3.10/site-packages/stlearn/app/source/forms/forms.py", line 8, in <module>
    from flask_wtf import FlaskForm
ModuleNotFoundError: No module named 'flask_wtf'
