I have installed Apache2 on the Raspberry and the idea is to run a Flask app. I managed to write a very simple app:
import requests from flask import Flask from flask import make_response from flask import render_template app = Flask(__name__) @app.route("/") def index(): url = "http://192.168.0.25/temp" temp = requests.get(url).content url = "http://192.168.0.25/humidity" hum = requests.get(url).content response = make_response(render_template("home.html", temp=temp, hum=hum)) return response if __name__ == '__main__': app.run(port=5001, debug=True)
which works but, as soon as I attempt to import libraries (even very basic ones) troubles begin. Just to give you the general picture there is no virtual environment involved and I have the standard install of Python.
As soon as I add import like:
from datetime import * from time import * import json
but this produce an error and Flask does not serve anything.
Thinking that - even if it seemed unlikely - I could miss some of these libraries, I tried to install them manually, e.g.
pip install json
and the same for 'time' and 'datetime', but this does not produce the desired outcome and I get
Could not find a version that satisfies the requirement json (from versions: ) No matching distribution found for json
I wanted to check if the libraries were there and were accessible to Python so, I wrote a very silly test, like:
from time import * while True: print('test') time.sleep(5)
which I run from the CLI,
$ python test.py, and it worked as expected.
So the questions are:
why are these library inaccessible/I get an error?
why the error about the matching distribution?
Pythonic thanks for your help :)
