Hi,

I try to run localstack and I got the following error:
C:\Python39\Scripts>python “C:\Python39\Scripts\localstack” start

The above exception was the direct cause of the following exception:

Can anyone assist please?

Hi @yaelm,

It looks like Docker might not be running on your machine, or you might need WSL installed/updated.
You can verify the first option by checking if the Docker Desktop service is running under Services in Windows.
Alternatively, you can run docker run hello-world to check if you encounter the same ContainerException. If that’s the case, you might need to install or update WSL.
Let us know how it goes.

We do mention it in the essential prerequisites — Installation | Docs
