 @Jan-0 
 This is so cool! It does work now. Has it been published to the list of modules?
 If you or @wishmaster270 are somewhere near Cologne you or are invited for a free professional solo session of Feldenkrais Functional Integration or a free professional singing lesson!

 @coernel 
 Great to hear and you are welcome. I try to help where I can.
 I live about 30km south of Munich but thanks for your invitation.

 Hi Everybody out there using MMM-FRITZ-Box-Callmonitor, 
 I would love to use this Module, but I’m not really in the mod to code or to find errors.
 I tried to install your new branch under PiOS “Bookworm” but I get some errors using
 “sudo apt-get install python-dev libxml2-dev libxslt1-dev zlib1g-dev && sudo pip install fritzconnection”!
 The first error is: " E: For Package »python-dev« exists no Installationscandidate."
 The second error for pip install is: “externally-managed-environment …”
 How can I solve these problems?
 Sorry for my bad english, I’m german and over 60 years old.
 Thanks for helping.

 @xIExodusIx that’s due to changes in the handling of the python packages. I installed “fritzconnection” in a virtual environment: python -m venv venv source venv/bin/activate python -m pip install fritzconnectionto make the Callmonitor use the fritzconnection, I edited the nodehelper.js (in ~/MagicMirror/modules/MMM-FritzBox-Callmonitor-py3) in line 212 to look like this (user is “pi”, must be adapted if you use another user): pythonPath: '/home/pi/venv/bin/python',Don’t know if it’s the best solution, but it works. 
- 
 @rabbit83ka you can set the venv in the mm.sh that starts MagicMirror then you don’t need to do that 
- 
 @sdetweil Thanks, so it should look like this? #!/bin/bash # This file is still here to keep PM2 working on older installations. cd ~/MagicMirror export PYTHONPATH="/home/pi/venv/bin/python" DISPLAY=:0 npm start
- 
 @rabbit83ka no, execute the venv command to set the virtual environment in place of the export the same venv command you did before running pip 
- 
 @sdetweil I used your script fixuppm2.shwhen I set up the mirror 
 Now I modified ~/MagicMirror/installers/mm.sh to#!/bin/bash # This file is still here to keep PM2 working on older installations. cd ~/MagicMirror source venv/bin/activate DISPLAY=:0 npm startbut that doesn’t work, error occures again because node_helper doesn’t seem to use the venv. 
- 
 @rabbit83ka when I look at my .bashrc whichs sets up the default venv on shell open 
 I see# Virtual Environment Wrapper source /usr/local/bin/virtualenvwrapper.sh PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig export PKG_CONFIG_PATH cd ~this topic seems applicable
