If running from the snapcraft snap, inject the snapcraft and its "base" from the host to ensure parity. If not running from the snap, install from the store.

Have you checked that there is a bug report open for the issue you are trying to fix on [bug reports](https://bugs.launchpad.net/snapcraft)? - [ ] If this is a new feature. Have you discussed the design on the [forum](https://forum.snapcraft.io)? - [ ] Have you successfully run `./runtests.sh static`? - [ ] Have you successfully run `./runtests.sh unit`? ----- An easy way to test this is to install the snap, `snap run --shell snapcraft` and then run something like the following: ```python import os from snapcraft.cli import echo from snapcraft.project import Project from snapcraft.internal.build_providers import get_provider_for os.chdir('/home/sergiusens/source/test-project') Provider = get_provider_for('multipass') project = Project(snapcraft_yaml_file_path='snap/snapcraft.yaml') p = Provider(project=project, echoer=echo) p.create() ``` Which would result in, ``` sergiusens@tupa:~/source/snapcraft$ snap run --shell snapcraft sergiusens@tupa:~/source/snapcraft$ /snap/snapcraft/current/usr/bin/python3 Python 3.5.2 (default, Nov 23 2017, 16:37:01) [GCC 5.4.0 20160609] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import os >>> >>> from snapcraft.cli import echo >>> from snapcraft.project import Project >>> from snapcraft.internal.build_providers import get_provider_for >>> >>> os.chdir('/home/sergiusens/source/test-project') >>> Provider = get_provider_for('multipass') >>> project = Project(snapcraft_yaml_file_path='snap/snapcraft.yaml') >>> >>> p = Provider(project=project, echoer=echo) >>> p.create() Creating a build environment named 'oversubtle-jeremiah' Launched: oversubtle-jeremiah Setting up snapcraft in 'oversubtle-jeremiah' Waiting for pending snap auto refreshes. error: no changes of type "auto-refresh" found Setting up core 2018-06-29T15:35:27Z INFO Waiting for restart... core 16-2.33 from 'canonical' installed Setting up snapcraft snapcraft 2.42.1+git26.055e84a installed ```
