Flask - Elastic Beanstalk Deploy - requirements.txt non-zero exit status

问题

I'm able to run this web app locally that uses AWS for its db, but every deploy I end up getting the following error. I'm using Python 3 (3.4 per AWS requirements):

  2017-05-10 04:18:47,980 ERROR    Error installing dependencies: Command '/opt/python/run/venv/bin/pip install -r /opt/python/ondeck/app/requirements.txt' returned non-zero exit status 1   Traceback (most recent call last):
    File "/opt/elasticbeanstalk/hooks/appdeploy/pre/03deploy.py", line 22, in main
      install_dependencies()
    File "/opt/elasticbeanstalk/hooks/appdeploy/pre/03deploy.py", line 18, in install_dependencies
      check_call('%s install -r %s' % (os.path.join(APP_VIRTUAL_ENV, 'bin', 'pip'), requirements_file), shell=True)
    File "/usr/lib64/python2.7/subprocess.py", line 541, in check_call
      raise CalledProcessError(retcode, cmd)   CalledProcessError: Command '/opt/python/run/venv/bin/pip install -r /opt/python/ondeck/app/requirements.txt' returned non-zero exit status 1 (Executor::NonZeroExitStatus)

Here's what my requirements.txt looks like, which includes a lot of packages that are dependent upon others:

appdirs==1.4.3
asn1crypto==0.22.0
cffi==1.10.0
click==6.7

itsdangerous==0.24
Jinja2==2.9.6

Somehow solved this by ensuring I had virtualenv -p python3 VENV and then adding an .ebextensions folder with a .config file containing:

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