Issue deploying on heroku

[marvoh]

Hi,

I have the following issue when trying to deploy my app on heroku. How do i circumvent this?

     [InvalidArgumentException]

     The directory "/tmp/build_a6e06165a85f6c32e166adc6f2d83454/vendor/sonata-project/core-bundle/Resources/config/bower/../..

/public/components/cache" is not writable.

You could use a different directory for the cache, one which is writeable, see https://github.com/Spea/SpBowerBundle/blob/master/Resources/doc/configuration_reference.md for more info
