@duffybelfield I have a PR out with additions to the README that cover this: https://github.com/awslabs/aws-sam-cli/pull/395

Make sure python -m site --user-base is in your $PATH.

Also ran to problem when upgrading using pip install --user aws-sam-cli with the following details:

OS: macOS Sierra 10.12.6
Python version (using pyenv): 2.7.6

Pip version: pip 10.0.1 from /Users/xxx/.pyenv/versions/2.7.6/lib/python2.7/site-packages/pip (python 2.7)

[sanathkr]

@livingmine Which platform are you on? I don't know why clang is trying to use python.exe. Can you also try without --user flag?

This is not related to SAM CLI installation but something else going wrong with your Python installation

[livingmine]

@sanathkr macOS Sierra 10.12.6. Somewhere along the installation process lies this info

Failed building wheel for PyYAML

Running setup.py clean for PyYAML

Tried without --user but no luck. Possibly related to this https://github.com/pyenv/pyenv/issues/273, let me try their suggestions first.

[livingmine]

This https://github.com/pyenv/pyenv/issues/273#issuecomment-312404367 fixes the problem. Thanks.

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

[jfuss]

@nabels-coolblue That is not the case. Localstack has a requirement on Flask 0.10.1 and are pinning their versions. Localstack and SAM CLI most likely will not work together if install in the same location (due to how Python/PIP work and where they install).
