Ok, I figured out the cause of the problem. If you look your error stack, the process fails at the part

calling pip download -r /Users/rick/PycharmProjects/same_hello_world/hello_world/requirements.txt --dest /var/folders/nd/7xg436m51nb5k7zc7pmc1bp80000gn/T/tmpym0ydzw_ PythonPipBuilder:ResolveDependencies failed

I tried to execute that command in the command prompt to see what happens, in my case it was:

pip download -r C:\Users\IdeaProjects\my_projects\requirements.txt --dest C:\Users\USER~1\AppData\Local\Temp\tmp9ya2xf94

After some search, I figured out that I had to add to my path environment variable the following paths: D:\Anaconda3; D:\Anaconda3\Scripts; D:\Anaconda3\Library\bin

@rickbhardwaj I am getting exactly the same error. What did you do eventually to solve it? My environment details are:

• Windows 10
• Intellij 2019.3.3
• sam version 0.44.0
• docker version 19.03.8

I had exactly the same code running successfully (build, invoking function, creating stack) on another machine (at my workplace), the only difference is that that docker version there was 19.03.05. Now with covid19 we were given other machines to work from home. I am not working behind any VPN or proxy for the time being therefore I would expect for the code to run.
