Source maps not found

Description

Hi!

I get the following error when only importing ui and calling run():

FileNotFoundError: [Errno 2] No such file or directory: '/home/aaad/server/.env/lib/python3.9/site-packages/nicegui/static/socket.io.min.js.map'
http://localhost/_nicegui/1.2.6/dependencies/74/mermaid.min.js.map not found

The file /home/aaad/server/.env/lib/python3.9/site-packages/nicegui/static/socket.io.min.js.map does not exist.

My version is 1.2.6 (python3 -c 'import nicegui; print(nicegui.__version__)').
My python version is 3.9.2.

import os.path
import platform
from pathlib import Path
from nicegui import ui

print(platform.system())
directory = Path(ui.__file__).parent / 'static'
print(f'{directory = }')
print(f'{os.path.abspath(directory)  = }')
print(f'{os.path.realpath(directory) = }')

returns

Linux
directory = PosixPath('/home/aaad/server/.env/lib/python3.9/site-packages/nicegui/static')
os.path.abspath(directory)  = '/home/aaad/server/.env/lib/python3.9/site-packages/nicegui/static'
os.path.realpath(directory) = '/home/aaad/server/.env/lib/python3.9/site-packages/nicegui/static'

Thanks, @aaad, for this thorough report!
This is known, non-critical behavior. The .js.map files are used for debugging and only requested when the JavaScript console is opened. See #716 for a similar issue.
Although we're currently waiting for #658 to improve the overall dependency management, I'll leave this issue open for later.

With #658 and #1134 now being implemented, it was pretty easy to add source maps for socket.io and highcharts. I'll close this issue as completed. It will be released with version 1.3.0. 🙂
