Strruggling to install on Win 10

[jimmyeao]

I ended up having to install Visual Studio C++ tools to get it to compile, then had to install pyaudio manually because the compile fails. Now when I try and open LEDFX I get this:

(ledfx) C:\Users\jimmy>ledfx --open-ui
Loading configuration file from C:\Users\jimmy\AppData\Roaming\.ledfx
Could not import the PyAudio C module '_portaudio'.

I get the same issue, would love to know how to install it on windows.

[dshokouhi]

Finally got it to work, I had to run conda install -c anaconda portaudio from: https://stackoverflow.com/questions/50243645/i-cant-import-pyaudio

then ledfx was able to start

[jimmyeao]

solved with conda install -c anaconda pyaudio

The install documentation has NO mention of C++, so, even with this command added, that documentation is STILL incomplete/inaccurate. I'm still trying to work out the exact step by step procedure to install it from a fresh copy of Win10.

Oh, and adding thoses C++ tools and this command still didn't work for me.

I'm quite surprised/disappointed that the author of LedFX hasn't fixed his install documentation.

It also seems to have blue screened my windows box (looks like a problem related to the audio driver) after a couple of hours of running. I have an old laptop I'm going to stick Linux on and use that.

Have a look at https://ledfx.readthedocs.io/en/latest/index.html

Yep, that was my starting point, and it does not work at all with a fresh install of Windows 10 (I use a VirtualBox VM environment with sound enabled to test). That would be:

1. Download/install Anaconda
2. Open up an Anaconda 32 bit shell
3. conda create -n ledfx
4. conda activate ledfx
5. conda config --add channels conda-forge
6. conda install aubio portaudio pywin32
7. pip install ledfx

[Mattallmighty]

Can you please show doing the steps listed above in Anaconda navigator -> environments -> ledfx -> Open terminal. Paste your terminal commands on https://pastebin.com/ and send me the link.

From a freshly patched install of Windows 1909 build in VirtualBox with the audio input and output enabled. Chrome, 7-Zip and the Arduino IDE were previously installed and the most recent version of Anaconda JUST installed. I ran the commands from the '"Anaconda Prompt (anaconda 3)". The documentation page didn't mention anything about using Anaconda Navigator :
