Installazione pyaudio con pip in una virtualenv

Question

Sto cercando di installare pyaudio con pip:

pip install pyaudio 

In un virtualenv ma sto ottenendo un errore:

error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

Cosa sto sbagliando? Sono nuovo in virtualenvs.

* Sono in grado di installare altri pacchetti. Sto affrontando un errore solo per il pacchetto pyaudio.

Tra l'altro io sono nell'ambiente:

(ENV) mertyildiran@Corsair:~/Downloads/VirtualEnvironment/vir1/MyProject$ 

Answer 1

Alcuni pacchetti richiedono il sostegno della non-Python software, come librerie condivise. Questi non possono essere installati tramite pip (non sono pacchetti Python!). In genere, installa questi sull'host utilizzando il gestore di pacchetti dell'host (apt-get o yum o dnf, ecc.) Oppure si utilizza qualcosa come Docker per incapsulare sia le dipendenze che l'applicazione.

Nel tuo caso, pyaudio richiede un numero di librerie, incluso almeno portaudio. Dovrai installare i pacchetti di sviluppo appropriati sul tuo sistema, come suggerito nei commenti sulla tua domanda.

Answer 2

Questo ha funzionato per me, ho avuto lo stesso problema:

se si desidera installare PyAudio all'interno di un virtualenv, installare gli header di sviluppo PortAudio da APT, quindi PyAudio:

sudo apt-get install portaudio19-dev 
pip install --allow-unverified=pyaudio pyaudio
