Errore nel tentativo di installare libjpeg-devel con beanstalk elastico

Question

Sto cercando di ridimensionare le immagini sulla mia applicazione Django in esecuzione su AWS Elastic beanstalk, quindi sto cercando di installare Pillow per fare il lavoro.

Come descritto in alcuni post precedenti, sto aggiungendo

packages: 
    yum: 
    libjpeg-devel: '6b' 

in cima alla mia .ebextension/myapp.config

mio requirement.txt comprende:

Django==1.6.7 
boto>=2.32.1 
django-filter>=0.7 
django-password-reset>=0.7 
django-storages>=1.1.8 
django-taggit==0.12 
djangorestframework>=2.3.13 
django-bootstrap3>=4.11.0 
django-bootstrap3-datetimepicker>=2.2.3 
python-dateutil>=2.2 
pytz>=2014.2 
six>=1.7.3 
wsgiref==0.1.2 
yolk==0.4.3 
Pillow==2.5.3 
googlemaps==1.0.2 
MySQL-python>=1.2.5 

Ma quando io o eb start o git aws.push, ottengo il seguente errore nel mio ceppo Beanstalk elastico:

Answer 1

sono stato in grado di farlo installare utilizzando il pacchetto libjpeg-turbo-devel senza la versione specifica. Il YAML è qui sotto:

packages: 
    yum: 
     libjpeg-turbo-devel: [] 

Se specificamente bisogno di quella versione, si potrebbe desiderare di indagare il libjpeg-turbo equivalente.

Un modo per capire manualmente queste cose è SSH in un'istanza reale che si trova nel proprio ambiente o avviarne una nuova.

In questo caso, per testare questo, quando ho SSH'd e fatto funzionare l'yum install, questo è accaduto:

[ec2-user@ip-xxx-xx-xx-xxx ~]$ sudo yum install libjpeg-devel 
Loaded plugins: priorities, update-motd, upgrade-helper 
Resolving Dependencies 
--> Running transaction check 
---> Package libjpeg-turbo-devel.x86_64 0:1.2.1-3.4.amzn1 will be installed 
--> Finished Dependency Resolution 

Come si può vedere, si risolve a libjpeg-turbo-devel invece.
