Pipenv: Possible use-case for generating a requirements.txt from Pipfile and Pipfile.lock

[gekitsuu]

I'm working on a project using the Serverless framework (serverless.com) and the way Lambda's are uploaded is to bundle all the files in the directory. The way you typically do this with serverless is to do something like

pip install -r requirements.txt -t ./vendored

Then in your python handler you'd have

import sys; sys.path.append('./vendored')

With pipenv I get the .venv directory but I'm not sure I want to bundle the whole virtualenv and upload that to AWS (or Google/azure) It would be nice if there was a command to generate a requirements.txt like output or install to a specific directory instead of a virtualenv for this sort of use case.

$ pipenv install --requirements.

The requirements outputted are mixed with pipenv messages.

No package provided, installing all dependencies.
Pipfile found at /Users/foobarquaxx/Code/pipenv/Pipfile. Considering this to be the project home.

"no package provided" is stderr, not std out. if you pipe this output, it will be clean.

[FooBarQuaxx]

If you starting fresh, will get some stdout that's not related to the requirements though.

ah, let's clean that up

https://github.com/kennethreitz/pipenv/commit/09d5951bd4e285f6039c692d33af6ada5aa7150c

[kennethreitz42]

all better!

[FooBarQuaxx]

@kennethreitz I don't think that fixes everything. You should also take care of virtualenv output I guess.

[kennethreitz42]

i believe i did that in another commit

[kennethreitz42]

all tested and working here
