Trouble installing Flask application

First time user of PythonAnywhere. Ops is not my wheelhouse so keep that in mind. Also, the getting started walkthrough isn't super helpful. I had to google to find out how to get code into my account.

I've got my free account ready for testing.
I cd into the mysite folder.
I've git cloned my repository
I run pip install - requirements.txt and everything goes well, until the end when I get the following output:

Is there something I'm missing? Am I skipping a step, or doing something wrong? I'm pretty sure my process is legit because there's only 2 steps: clone the app, install requirements. But anyway, I'd love some feedback that would help me determine what's going wrong.

Also, there's nothing in my code referencing flask_app.

OK, there are a couple of things that should help. You need to use the --user flag when installing your requirements on PythonAnywhere, ie.

pip install --user -r requirements.txt

The other thing is that once they're installed, you'll need to modify your WSGI file (linked from the "Web" tab to put the path where you installed your app onto sys.path and to import the appropriate name from your main module.

Give that a go and post back here if it still doesn't work.

One other thing: someone just sent us a link to a bug in pip that seems to happen with large requirements files and proxies (which impacts our free accounts). I think it might help to split your requirements file into a number of smaller ones and install them separately if you still get the 111 error when you use the --user flag.

Are you runnung pip from a virtualenv?

if not try the --user option to pip to install the dependencies to your home directory.

edit: just noticed, the duplication "Save button is the ultimate proofreading tool ;-)"

OK, we've discovered a workaround for this: run this in a bash console:

pip2.7 install --user -U pip==1.4

This will downgrade pip for your account to a version without the proxy bug.

Very useful to me.
