I am working on a flask project. These are my dependencies in requirements.txt and it is working fine:
pytest==6.2.4
black==21.7b0
Flask-JWT-Extended==4.2.3
Flask-RESTful==0.3.9
Flask-SQLAlchemy==2.5.1
PyMySQL==1.0.2
Flask-MySQLdb==0.2.0
flask-marshmallow==0.14.0
marshmallow-sqlalchemy==0.26.1
marshmallow
flask-uploads==0.2.1
Werkzeug==0.16.0
python-dotenv==0.19.0
flask-migrate==3.1.0
ldap3==2.9.1
psycopg2==2.9.1
The reason that I am using Werkzeug==0.16.0 is explained in this post in StackOverflow:
flask_uploads: ImportError: cannot import name 'secure_filename'
I am trying to use pipenv instead of venv.
So after creating the project and adding the pipfile to the project, I run this command:
pipenv install -r requirements.txt
But I get an error:
[pipenv.exceptions.ResolutionFailure]: Warning: Your dependencies could not be resolved. You likely have a mismatch in your sub-dependencies.
First try clearing your dependency cache with $ pipenv lock --clear, then try the original command again.
Alternatively, you can use $ pipenv install --skip-lock to bypass this mechanism, then run $ pipenv graph to inspect the situation.
Hint: try $ pipenv lock --pre if it is a pre-release dependency.

There are incompatible versions in the resolved dependencies:
werkzeug==0.16.0 (from -r C:\Users\{user}\AppData\Local\Temp\pipenv4r7ldp86requirements\pipenv-ajg0yy6e-constraints.txt (line 15))
werkzeug>=0.14 (from flask-jwt-extended==4.2.3->-r C:\Users\{user}\AppData\Local\Temp\pipenv4r7ldp86requirements\pipenv-ajg0yy6e-constraints.txt (line 3))

How can I solve this problem?
