How To…

This document describes how to do different things or fix different problems.

FileNotFoundError: [Errno 2] No such file or directory: 'timeout'

This can show up when you run make test

(venv)$ make test
>               raise child_exception_type(errno_num, err_msg)
E               FileNotFoundError: [Errno 2] No such file or directory: 'timeout'

/Users/tcf/.pyenv/versions/3.5.2/lib/python3.5/ FileNotFoundError
----------------------------- Captured stdout call -----------------------------
['timeout', '1.0s', '/usr/bin/env', 'python3', '-u', '']
===================== 2 failed, 20 passed in 27.72 seconds =====================
make: *** [test] Error 1

If this occurs, it’s likely because the GNU timeout program does not exist on the system that is running the test. timeout is part of the GNU Coreutils, so make sure that is installed on the system.

To install on different systems, you would use:

$ brew install coreutils --with-default-names  # Mac OS X
$ export PATH=/usr/local/opt/coreutils/libexec/gnubin:$PATH  # Mac OS X
$ sudo apt-get install coreutils  # Ubuntu-like
$ sudo yum install coreutils  # Fedora-like

All the tests were skipped

When you run the tests, you find that every test has an s for “skipped”.

(venv)$ make test
============================= test session starts ==============================

plugins: mock-1.5.0, django-3.1.2

tests/ ssssssssssssssssss

===================== 4 passed, 18 skipped in 0.39 seconds =====================

When this occurs, it’s because the .env file has not been configured. To fix this, you will need to follow the instructions in Modify Settings.

Make changes to the models

In order to make changes to the models, we also need to have a Django application that can make the migrations. In order to do this, we should make sure that we’ve set up the virtual environment in the example folder and then run make makemigrations from the root of the project.

(venv)$ deactivate  # if you're still in the previous virtual environment
$ cd example
$ python3 -m virtualenv venv
$ source venv/bin/activate
(venv)$ python3 -m pip install -r requirements.txt
(venv)$ deactivate
$ cd ..
$ make makemigrations
