Impossibile installare gevent OSX 10.11

Question

Cercando di installare gevent utilizzando Homebrew su OSX 10.11 ultima beta pubblica. Quando si esegue l'installazione, emette i seguenti errori (scusate la grande parete di codice, non so esattamente dove l'errore è)

Answer 1

uso CFLAGS='-std=c99' pip install gevent per risolvere questo problema.

su OS X 10.11, clang utilizza c11 come valore predefinito, quindi è sufficiente tornare al c99.

Answer 2

Ho incontrato lo stesso problema sul mio OSX 10.10.5, si tenta di installare flask-socketio, che ha gevent come una dipendenza, ma:

sudo CFLAGS='-std=c99' pip install flask-socketio 

mi ha dato

Successfully installed flask-socketio-0.6.0 gevent-1.0.2 gevent-socketio-0.3.6 gevent-websocket-0.9.5 

Quindi, tonicbupt di la risposta ha funzionato anche per questo.

Answer 3

ho sprecato il mio tempo per due giorni e la soluzione qui di seguito per gli utenti Mac ...

pip install gevent==1.1b5 

Soluzione: gevent fails to install in a python virtual environment on OS X Capitan

Answer 4

Su Mac OS X El Capitan, ho dovuto fare entrambe le cose che sono stati menzionati nelle risposte precedenti, impostare la variabile CFLAGS e downgrade di gevent, ma ho dovuto usare la versione 1.0 per cancellare gli errori del compilatore.

CFLAGS='-std=c99' pip install gevent==1.0 

Answer 5

Come descritto nella sua PyPI instruction,

pip install --pre gevent

dovrebbe installare una versione release candidate (1.1rc4 come di Feb 22, 2016), che lavora per OS X 10.11.

Answer 6

In questo momento, gevent 1.1.0 final viene rilasciato sotto forma di una ruota binaria per OS X e pip lo installerà di default. Una ruota binaria per gevent 1.0.2 per OS X è disponibile anche per coloro che non possono eseguire l'aggiornamento alla versione più recente. Entrambi sono stati testati per l'installazione su OS X 10.11 con Python 2.6 e 2.7 distribuiti da Apple, oltre al 2.7 Python scaricato da python.org. (Se hai problemi nell'installare le ruote binarie, potrebbe essere necessario aggiornare la tua versione di pip.)

Quindi non ci dovrebbe essere alcuna necessità di impostare alcun CFLAGS speciale a meno che non sia necessario compilare 1.0.2 dalla sorgente. (1.1.0 non soffre di questo problema.)

Si noti che le ruote sono distribuite per le build unicode "strette" di Python, quindi se si utilizza una build "ampia", è necessario compilare da fonte. In questo caso, l'impostazione di CFLAGS = "- std = c99" è richiesta per gevent 1.0.2 (ma non 1.1.0.)
