Hi, the problem when starting mkchromecast , I tried to deal with /home/minimal/.local/lib/python3.8/site-packages/markupsafe/init.py But nothing works out.

./mkchromecast Mkchromecast v0.3.9 Creating Pulseaudio Sink... Open Pavucontrol and Select the Mkchromecast Sink. Starting Local Streaming Server Traceback (most recent call last): File "./mkchromecast", line 289, in CastProcess(mkcc).run() File "./mkchromecast", line 69, in run self.start_audiocast() File "./mkchromecast", line 94, in start_audiocast import mkchromecast.audio File "/media/mkchromecast/mkchromecast/bin/../mkchromecast/audio.py", line 16, in from mkchromecast import pipeline_builder File "/media/mkchromecast/mkchromecast/bin/../mkchromecast/pipeline_builder.py", line 11, in from mkchromecast import stream_infra File "/media/mkchromecast/mkchromecast/bin/../mkchromecast/stream_infra.py", line 4, in import flask File "/usr/lib/python3/dist-packages/flask/init.py", line 14, in from jinja2 import escape File "/usr/lib/python3/dist-packages/jinja2/init.py", line 33, in from jinja2.environment import Environment, Template File "/usr/lib/python3/dist-packages/jinja2/environment.py", line 15, in from jinja2 import nodes File "/usr/lib/python3/dist-packages/jinja2/nodes.py", line 23, in from jinja2.utils import Markup File "/usr/lib/python3/dist-packages/jinja2/utils.py", line 676, in from markupsafe import Markup, escape, soft_unicode ImportError: cannot import name 'soft_unicode' from 'markupsafe' (/home/mini/.local/lib/python3.8/site-packages/markupsafe/init.py) Killed

I also suggested installing the markupsafe version==2.0.1 in requirements.txt but it didn't work because werkzeug 2.2.1 requires MarkupSafe>=2.1.1

after that, I tried to specify in requirements.txt werkzeug==2.1.2, but also nothing worked File "/usr/lib/python3/dist-packages/flask/init.py", line 21, in from .app import Flask File "/usr/lib/python3/dist-packages/flask/app.py", line 32, in from werkzeug.wrappers import BaseResponse ImportError: cannot import name 'BaseResponse' from 'werkzeug.wrappers' (/home/mini/.local/lib/python3.8/site-packages/werkzeug/wrappers/init.py) Killed

According to https://stackoverflow.com/a/73726848 , this is a compatibility issue between jinja2 and markupsafe. The recommendation from the answer linked above us to upgrade jinja2.

Beyond that, python 3.8 is pretty old (Debian is shipping python 3.11 in stable these days). So that might be something else to look into.

Marking this as closed, since it's not an mkchromecast issue.

The root cause with your issue stems from a dependency management conflict between two software ecosystems. According to the error message, your 'werkzeug' was installed using 'pip' at the path /home/mini/.local/lib/python3.8/site-packages/werkzeug. The 'flask' that depends on it was installed using 'apt' at the path /usr/lib/python3/dist-packages/flask. The versions of the two are not compatible. In fact, there is a version of 'werkzeug' in the system that 'flask' correctly depends on, but the Python interpreter prioritizes the 'werkzeug' installed by 'pip', leading to this issue. There are typically two solutions to this problem: (1) Use 'pip' to uninstall werkzeug, and then reinstall it using 'apt', or uninstall 'flask' using 'apt' and reinstall it using 'pip'. (2) Use Python's imp module to customize the path and import the 'werkzeug' from the 'apt' path before importing 'flask'. An example is as follows:

import imp
path = ['/usr/lib/python3/dist-packages']
fp, pathname, description = imp.find_module('werkzeug', path)
imp.load_module("werkzeug", fp, pathname, description)

Hope my diagnosis is helpful to you! @yandex8
