[Setup Issue] Can not start the dev server in setup process while using Docker on Windows

Platform: Docker on Windows @justcrossheaven and @manishaag7 both have been facing the following issue while using python -m scripts.start while setting up the project.

Tried solutions(not worked)

• deleting oppia_tools directory
• pip install future and six

Diagnosis checks

• python -c "import Queue" - No output and it is the expected behavior.

@manishaag7 only got python 2 installed in his laptop.

Hey @gp201 and @EricZLou , Thank you for your help. Finally the development server started successfully. I can access the website on localhost:8181. To make it work, I had to downgrade my WSL 2 to WSL 1 and then I started the elastic search server on a separate terminal using this command ./oppia_tools/elasticsearch-7.10.1/bin/elasticsearch .

Everything is working except for this page http://localhost:8181/community-library. It is not able to fetch the lessons from the elastic search server. On the terminal is showing timeout error and elastic search is not able to fetch data.

@EricZLou and @gp201. I had to reset my Ubuntu 18.04 on WSL. Cleared all the data. Then again tried installing Oppia and finally this time it worked. 🎉 . I would like to know the port number at which the Oppia is running. I am unable to find it. 😅
