Running Python Script to LocalHost from Linux Terminal

Question

I am working through Miguel Grinberg's Flask Mega-Tutorial and am unable to run the basic Hello World Flask app in Local Host:

run.py:

#!flask/bin/python
from app import app
app.run(debug = True)

I am running the following in the Ubuntu terminal:

chmod a+x run.py
./run.py

Which is generating the following:

bash: ./run.py: flask/bin/python: bad interpreter: No such file or directory

Appreciate the input.

Answer 1

You may have not created yet the virtual environment called "flask" (explained under the Installing Flask section), therefore the shebang line fails. I ran it without and with the virtenv and it works.

Check this topic to see if it helps: flask/bin/pip install flask==0.9 results in 'no such file or directory'.
