@johncblandii You are installing a py2 cli in py3. We don't yet support py3 due to some dependencies not being available. Please install with py2.

Closing issue. Please reopen if py2 does not work.

[sanathkr]

Dupe of #387.

[johncblandii]

You are correct, @jfuss. python is 2.7, but pip was in 3.6. I've addressed and all is well. Thx for the prompt response.

@sanathkr, not really. I'm not asking for 3.6 here. I was just trying to get it to work.

[ayqazi]

So even though my code runs in Python 3.6, I have to run sam in 2.7?

[kristof9851]

Then why does the documentation say that Python3.6 is supported too?

"Python2.7 or Python3.6"

https://github.com/awslabs/aws-sam-cli#prerequisites

[jfuss]

@ayqazi As of now this is correct. Version 0.3.0 only supports Py2.

@kristof9851 That is the documentation of the develop branch which is ahead of all releases. Version 0.3.0 is only Py2 compatible.

[ndelvalle]

I'm using sam AM CLI, version 0.5.0, Python 2.7.15 and pip 18.0 from /usr/local/lib/python2.7/site-packages/pip (python 2.7) and I'm having this problem, any ideas?

[jfuss]

@ndelvalle Can you pip freeze and tell me what version of aws-sam-translator you have?

[ndelvalle]

aws-sam-translator==1.6.0 @jfuss

[jfuss]

@ndelvalle Are you sure you installed this in Py2? I would uninstall and see if sam is still callable. Something is funky here and not sure what it is. You shouldn't have any problems with this.

What is the output look like when the command fails?

[ndelvalle]

@jfuss I ran pip uninstall aws-sam-cli and I was not able to run sam (zsh: command not found: sam) then I installed again pip install --user aws-sam-cli try to run sam local start-api and this is the result:

I was able to run this in the past, not sure what update I made to break it.
PD: Thanks a lot for the help.

[jfuss]

@ndelvalle Check out: #425

[ndelvalle]

Thanks, @jfuss doing:

pip uninstall backports.ssl-match-hostname
pip install -U docker

As posted here made it work 🙌🏻

[LewS]

Looks like this issue is back.
Getting
Command 'local' is not configured correctly. Unable to import 'samcli.commands.local.local'
with the usual trace ending .... ImportError: No module named ssl_match_hostname
pip uninstall backports.ssl-match-hostname
pip install -U docker
Did not fix, nor did updating packages, awscli aws-sam-cli & backports.ssl-match-hostname
Clearly a problem with the backports.ssl-match-hostname.
Local version is backports.ssl-match-hostname-3.5.0.1
Current work around is to change default python to 3.6 where backports.ssl-match-hostname is not needed.

[omar-nahhas]

HORRIBLE user experience! It was so easy to install when it was a go lang application... There is no way I can convince my team of using this application when there is so much work around just to get it installed.

[mark-hayward]

I am now receiving this error. Seems to be after I upgraded to Ubuntu 1810. Not sure if it's related?

[Tolsto]

Have the same issue since I've upgraded to Ubuntu 18.10. None of the solutions suggested in this thread have worked for me.
I worked around the problem by installing the master branch with Python 3.

[Vluf]

Also having this issue

[harprit]

Thanks. To resolve above issue on Ubuntu 18.10, the second solution here worked for me..
