How do I run a simple python 2.7 project in codenvy?

Question

I'm trying to use codenvy.com to run a simple python 2.7 project, but I get this error:

[ERROR] testing-python2_unpack/requirements.txt: no such file or directory

what is the requirements.txt file, where to put it and what should it be to run a simple

print "Hello world!"

Answer 1

The requirements.txt lists the package dependencies for your project, to be installed alongside it -- it's an essential attribute of python packages.

You can probably get away with an empty file if your package has no dependencies -- just run

$ touch requirements.txt

to create an empty file in your package.
