Lots of our students got the impression that "pip freeze > filename" was the standard way of creating a file from the shell, which caused some really confusing problems later on!
We had a surprising number of students who created runtime.txt with the `pip freeze > runtime.txt` method, and then added a Python version at the end. This caused endless confusion when Heroku told them that (Django==1.7.1 dj-database-url==0.3.0 waitress==0.8.9 whitenoise==1.0.5 psycopg2==2.5.3 python-3.4.2) was not a runtime supported by the cedar-14 stack - at one point we had five coaches standing around one poor student trying to work out what had gone wrong! I've tried to make it clearer that - you create runtime.txt using your editor - only the python version should be included in the file I've also removed the word "simply" from these instructions in line with the Coaching Guide.

Thanks for updating this @pozorvlak - the errors seems so glaringly obvious now but it confused me and three other coaches for quite a while. |
