Checking installations

Let’s check some installations/configurations

Python

To check whether python is installed correctly. In windows: open a CLI, type:

py

and press enter. If the commmand is known that’s OK! If it is NOT: open a browser on python.org, download the python installation. While running this installion make sure you twice(!) select that the PATH variable has to be set! Open a new CLI, check py is now recognized!

Also python should be recognized:

python

(or python3)

• Python command not recognized: Check your PATH variable setting (advanced system settings) to see if python and the scripts are correctly configured.

Flask

On a CLI, type

flask --version

If that’s recognized that means flask is installed. If not, use:

pip install Flask

Some more things that could help you trouble shoot:

• Flask not working: Check if you have the correct virtual env ‘activated’ Have you installed it correctly in the environment?
• Flask not working in Visual studio code: Flask run command not working: Are you using the correct command? This can very among versions. Check version by running ‘flask –version’ Flask not showing HTML template: make sure to put the templates in a folder called ‘templates’.
