First install a few dependencies:
sudo apt install gcc g++ make python3-dev python3-venv libffi-dev libsodium-dev libapt-pkg-dev libarchive13 squashfs-tools patchelf
Create and activate a new virtual environment:
mkdir -p ~/venv/snapcraft
python3 -m venv ~/venv/snapcraft
source ~/venv/snapcraft/bin/activate
Make sure pip is up-to-date:
(snapcraft) $ pip install --upgrade pip
Install snapcraft (and its dependencies):
(snapcraft) $ pip install -r requirements.txt .
To see all the commands and options, run snapcraft --help.
We'd love the help!

- Our mailing list is snapcraft@lists.ubuntu.com
- We can also be found on the #snappy IRC channel on Freenode
You'll need to install the development dependencies, and you'll also probably want to install it in editable mode so any changes you make take affect:
(snapcraft) $ pip install -r requirements.txt -r requirements-devel.txt --editable .
See the Testing guide.
-
bin: Holds the main snapcraft script. Putting this bin in your PATH or directly running scripts from it will find the rest of the source tree automatically.
-
examples: Entering the subdirectories and running
../../bin/snapcraft snapwill generally yield interesting results. These examples will give you an idea of what snapcraft can do. These examples are not used during automated testing, they are simply for experimenting. -
plugins: Holds yaml metadata for the current snapcraft plugins.
-
tests: Tests, obviously.
unitholds Python unit tests andplainboxholds plainbox integration tests. -
