Env. Variables not set while running Minimal Flask application

Question

I am trying to follow the flask documentation on my windows machine given at the following link: http://flask.pocoo.org/docs/0.11/quickstart/#debug-mode

Firstly I wrote

Answer 1

Here is what worked for me:

• Step 1: Open your CMD Command prompt
• Step 2: Go on the same directory in which my python file was on.
• Step 3: in the CMD command prompt run the command setx FLASK_APP sqlAlchemy.py
• Step 4: close terminal
• Step 5: In the CMD command prompt run the command python - m flask run

I have an Alienware laptop and am using Windows 10.

Not sure it worked but it was a combination of trial and ever. Depending on the OS you have the solution will vary it seems. IT could be an environmental variable issue but again not sure.

- Here are other possible solutions that didn't work for me but I gathered them up as possibilities.

• OPTION 2
• set FLASK_APP=sqlalchemy.py
  • flask run
• OPTION 3
• set FLASK_APP=app
• set FLASK_ENV=development
  • flask run Hope this helps.
