dev/urandom - strerror: file not accessible

Question

I am using google app engine to create an app that accesses the prediction api. I am able to run the app when I update it on the website, however I am not able to run it on localhost:8080.

I am an absolute noob, any help is highly appreciated.

Here's the error:

<type 'exceptions.IOError'>: [Errno 13] file not accessible: '/dev/urandom'
  args = (13, 'file not accessible')
  errno = 13
  filename = '/dev/urandom'
  message = ''
  strerror = 'file not accessible' 

Answer 1

How are you accessing /dev/urandom? That file is not accessible in production and should not be accessible in the dev_appserver. If you want to generate random data, use os.urandom() which will work correctly in both the local and production environments.
