First, create a virtual environment for chalice:
$ virtualenv venv-chalice $ source venv-chalice/bin/activate
Keep in mind that chalice is designed to work with AWS Lambda, so you should ensure your virtual environment is created with python 2.7, which is the version of python currently supported by AWS Lambda.
Next, you'll need to install chalice. The easiest way to configure this is to use:
$ pip install -e .
Run this command the root directory of the chalice repo.
Next, you have a few options. There are various requirements files depending on what you'd like to do.
For example, if you'd like to work on chalice, either fixing bugs or
adding new features, install requirements-dev.txt:
$ pip install -r requirements-dev.txt
If you'd like to just build the docs, install requirements-docs.txt:
$ pip install -r requirements-docs.txt
And finally, if you only want to run the tests, you can run:
$ pip install -r requirements-test.txt
Note that requirements-dev.txt automatically includes
requirements-test.txt so if you're interested in chalice development you
only need to install requirements-dev.txt.
