Sharing my solution to this issue.

While adding python packages path to your $PATH like @jfuss mentions above - I also had to add export /bin to my path - like this.

PATH=$USER_BASE_PATH/bin:$PATH

Link to PR #395.

Sharing my solution as well.

I had a version conflict. After installing localstack next to sam-local, sam-local would complain about a dependency called Flask.

Traceback (most recent call last):
  File "c:\python36\lib\site-packages\pkg_resources\__init__.py", line 574, in _build_master
    ws.require(__requires__)
  File "c:\python36\lib\site-packages\pkg_resources\__init__.py", line 892, in require
    needed = self.resolve(parse_requirements(requirements))
  File "c:\python36\lib\site-packages\pkg_resources\__init__.py", line 783, in resolve
    raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.ContextualVersionConflict: (Flask 0.10.1 (c:\python36\lib\site-packages), Requirement.parse('Flask~=1.0.2'), {'aws-sam-cli'})

After updating pip with the following command, the version conflict had disappeared.

python -m pip install --upgrade pip
