Intento instalar Watchman en Ubuntu 20.04.01:

 guettli@yoga15:~/tmp$ python3 -m venv pywatchman-test guettli@yoga15:~/tmp$ cd pywatchman-test guettli@yoga15:~/tmp/pywatchman-test$ . bin/activate (pywatchman-test) guettli@yoga15:~/tmp/pywatchman-test$ pip install pywatchman

falla:

Encontré una manera de resolver esto: si desinstalo pywatchman e instalo wheel , funciona bien.

Me gustaría crear un parche para Watchman, para que esto funcione desde el primer momento.

¿Cómo podría solucionarse esto, para que en el futuro esto no suceda más?
