Hi all,

I installed ROS on windows 10 according to "Instration on Win10". But I faced with "ImportError" when I run "roscore" command. Error message is following,

c:\opt\ros\melodic\x64\bin>roscore Traceback (most recent call last):
File "c:\opt\ros\melodic\x64\bin\roscore", line 36, in <module> from rosmaster.master_api import NUM_WORKERS ImportError: No module named rosmaster.master_api

I saw this issue. But it's on linux ! How can I fix this issue ?

With Best Regards.

In the console window, Did you run c:\opt\ros\melodic\x64\bin\setup.bat?

Could you post the output of:

set ROS

I had run "c:\opt\ros\melodic\x64\setup.bat" command on Visual Studio command prompt. But no message displayed ! And "c:\opt\ros\melodic\x64\bin\setup.bat" is missing, it is in "c:\opt\ros\melodic\x64\setup.bat". This batch file is correctly ?
