Does an error occur when converting a python program using eel to exe?

Question

Python

I created this python script:

import eel 
import pyowm
# api key
owm = pyowm.OWM ( '80e8e723ef945c291f4661f5898f93e0',language = "RU" )
@eel.expose
def get_weather(place):
    #owm
    observation = owm.weather_at_place(place)
    Observation = weather = observation.get_weather()
    #temp
    Temp = weather.get_temperature('celsius')['temp']
    #status
    Status = weather.get_detailed_status()
    return "В городе "+place+' температура '+str(Temp)+' °С ,' + Status

#eel
eel.init("web")
eel.start("main.html", size=(500 , 550))

it works properly.
But when converting to exe with pyinstaller, an error occurs

Error: 404 Not Found
Sorry, the requested URL 'http://localhost:8000/main.html' caused an error:

File does not exist.

Also I used auto_py_to_exe and
it didn't help either.

Answer 1

How to make pyinstaller take everything with it...

Answer 2

I have to convert to a single file and not with separate pieces such as html
