python - Invalid requirements.txt on deploying django app to aws beanstalk

Question

I have been deploying my app without any issues to the beanstalk environment until my latest commit.

Now I get this

Time    Type    Details
2013-09-01 10:19:12 UTC+0800    ERROR   Failed to deploy application.
2013-09-01 10:19:11 UTC+0800    ERROR   Responses from [i-50f40d06] were received, but the commands failed.
2013-09-01 10:19:11 UTC+0800    ERROR   Your requirements.txt is invalid. Snapshot your logs for details.

The snapshot logs say this:

My requirements.txt is the same as before. I tried removing everything in the requirements.txt as well but I get the same error again which makes me think the problem was before requirements.txt was run.

I don't know the order in which things are deployed. ANyway, here is my config file:

packages:
  yum:
    libjpeg-devel: '6b'
    zlib-devel: []
    freetype-devel: []


container_commands:
  01_install_mysqldb:
    command: "pip install distribute==0.6.28; pip install mysql-python;"

    command: "python manage.py syncdb --noinput"
    leader_only: true
  03_createadmin:
    command: "python scripts/createadmin.py"
    leader_only: true
  04_collectstatic:

I had the exact same problem. The only thing that worked for me was (automatically) rebuilding my entire environment. You can do that in the AWS console. Go to your environment and click Actions > Rebuild Environment. This will take some time, afterwards it will automatically relaunch your app without this error.

Update:

The problem keeps returning so now and then. I figured out that something is going wrong when pip compiles psycopg, which is needed for postgreSQL support. Haven't found a real solution yet.
