sam local start-api gives error while testing SAM application in local

Question

Hi i have a sam application which one lambda function and can be invoked from rest endpoint which is working as expected but when i try to test the sam application locally using sam local start-lambda or sam local start-api or sam local invoke i get the error as :

    self.connect()
  File "C:\Users\divyanayan.awasthi\AppData\Roaming\Python\Python37\site-packages\docker\transport\npipeconn.py", line 31, in connect
    sock.connect(self.npipe_path)
  File "C:\Users\divyanayan.awasthi\AppData\Roaming\Python\Python37\site-packages\docker\transport\npipesocket.py", line 22, in wrapped
    return f(self, *args, **kwargs)
  File "C:\Users\divyanayan.awasthi\AppData\Roaming\Python\Python37\site-packages\docker\transport\npipesocket.py", line 50, in connect
    win32pipe.WaitNamedPipe(address, self._timeout)
pywintypes.error: (2, 'WaitNamedPipe', 'The system cannot find the file specified.')

Sam version used

SAM CLI, version 0.7.0

Is this because i dont have a docker running in my local or some other configuration is required .i have one .py class and template.yml file for SAM application.

Yes we need to install docker locally then sam local works as expected .if you are running sam local on windows then there might a problem to install docker installer as it needs Windows 10 Pro or enterpise version to install.

In case you dont have the above windows configuration then install docker toolbox
