Python 3 Wrapper not installing properly #845

The wrapper shouldn't be broken. I need a little more detail about what you saw when installing the wrapper. The username |

Hi and thanks for your reply, Here a full output code: Thank you! |
This means that you didn't re-install the wrapper. Before we go any further, I'm going to ask you try our newer python pkg called pyRF24. The install is much more automated and it doesn't need the C++ libs installed. I'm recommending this because troubleshooting the older python wrappers (what you're playing with now) is difficult when working remotely with... um, "non-experts" (no offense intended). These older python wrappers have become highly "nuanced" to get working correctly over the last 6 years.

FYI, I just tried a fresh install on my RPi4, and it worked without a problem. Here is what I executedpi@rpi4:~/github/RF24/build $ export RF24_DRIVER=SPIDEV
pi@rpi4:~/github/RF24/build $ echo $RF24_DRIVER
SPIDEV
pi@rpi4:~/github/RF24/build $ cmake ..

Good morning! Thank you so much for your answer - with your tips it's now working perfectly! This will lead to the files being downloaded locally on the rpi: Of course you need to install python and pip first: Don't forget to link the libboost afterwards: BR and ty again! |

I'm now adjusting the pyRF24 API to be drop-in compatible with these older python wrappers (pending nRF24/pyRF24#9) |

Hello everybody,
rasp4 with fresh Raspberry Pi OS lite.
Installed RF24 like stated in https://nrf24.github.io/RF24/md_docs_linux_install.html (automatic install with SPI option, activated spi before with raspi-config)
Tried to install Python 3 Wrapper using https://nrf24.github.io/RF24/md_docs_python_wrapper.html, install itself seems to work, but during last step when testing, i only get this error:
Python package seems to be installed for me, but i am not an expert:
Tried several other OS (buster, ...), everytime the same message. What am I doing wrong? Or is the Wrapper install broken?
Any help is greatly appreciated!
Thank you :)
