Not able to update Robot Framework version in Jython

I am currently using Robot Framework 3.2.1 and I also have Jython with Robot Framework version 3.1.2. I need to update the version of Robot Framework in Jython.

Executed the below command and getting an error:
C:\jython2.7.2\bin>pip install robotframework==3.2.1
Picked up JAVA_TOOL_OPTIONS: -agentlib:jvmhook
Traceback (most recent call last):
File “C:\jython2.7.2\Lib\”, line 161, in _run_module_as_main
return _run_code(code, main_globals, None,
File “C:\jython2.7.2\Lib\”, line 72, in run_code
exec code in run_globals
File "C:\jython2.7.2\bin\pip.exe_main
.py", line 5, in
ImportError: No module named _internal

Can anyone please help me resolve this issue as I am stuck at this point.
Also attached the screenshot for the same.
