Hello, how I can see there is error

ImportError: No module named future

You should precisely follow wiki instructions

http://ardupilot.org/dev/docs/sitl-native-on-windows.html

Try to use this commands to install required packets for python.

python -m ensurepip --user
python -m pip install --user future
python -m pip install --user lxml
python -m pip install --user uavcan

Thanks for replying. But I already have installed all the python packages. I well have cross checked and did rerun those commands again , its already there.

Above is the photo of those commands I rerun and cross checked.
Is there a particular location I keep these files in??
Or do I need to write something in mavgen.py??

According to log, somehow mavgen.py cant see this package, do You have Python folder in windows Environment Variables?

I have c:\python27 and c:\python27\scripts in variable “Path”

My cmd output:

C:\Windows\System32>python -V
Python 2.7.13

C:\Windows\System32>python -m pip install --user future
Requirement already satisfied: future in c:\python27\lib\site-packages

Hi Guys and Hi Nikita,
First of all Thank you for replying Nikita.

After almost 10 -12 hours and trying different things I finally can run the : #sim_vehicle.py -j4 --map

What I did is , I uninstalled the python packages from Windows Command Prompt and reinstalled them by using cygwin.The packages got installed in the same directory but now the program was able to find it(Wierd , but thats how it is.)

Then it did not find my g++ , then I again reran the cygwin setup and installed all the packages with g++ and c++ tags.

executed this before the sim_vehicle : export PATH=$PATH:$HOME/ardupilot/Tools/autotest
and then finally I could get the map running.

The documentation is little obscure and needs some refinement.

But Thanks to you for setting me on right track at first place.

@Jay_Jagtap Thanks for the success report. Please note that you can update the documentation with what you’ve found - there’s an “Edit on GitHub” link in the top-right-hand corner.
