Help on running Fava.

[Júlio Maranhão]

Today I started to use a fresh Beancount and Fava. I do not really "used" both before: it was only a couple of runs. As I remember, the versions was 'git master' and 1.6, respectively.

But because of problems with pip3 install/upgrade messing global-packages, I decided to learn and use python3 venv. I did a detailed cleanup to remove all pip3 installed packages and reinstall all cygwin python3-* packages. Job done.

You are using pip version 9.0.1, however version 18.0 is available.

You should consider upgrading via the 'pip install --upgrade pip' command.

Running Fava on http://localhost:5000

In the browser, all I get is ERR_EMPTY_RESPONSE. In the CLI I get:

AttributeError("'BufferedWriter' object has no attribute '_write_lock'",)

Traceback (most recent call last):

Keyboard Interrupt: shutting down

Aborted!

I fell like I am missing something simple. Any ideas?

P.S.: I did the same cleanup procedure to ansible (another venv). It worked.
