ImportError: Module use of python39.dll conflicts with this version of Python.

[Neil Benn]

Hello,

  I've come back to an existing project after a reboot of my computer and I'm now getting the error when I execute a build:

ImportError: Module use of python39.dll conflicts with this version of Python.

  This doesn't happen when I do a pristine build; only the second time I build a project.  I've seens reports on this for older versions of ncs but I'm on version 2.42.  Can you please assist as to why I may be getting this error?

  Thanks.

Cheers,

Neil

Hi Neil,

You might have conflicting versions of Python on your system.
For testing, check if reinstalling your NCS v2.4.2 fixes the error.

Best regards,

Apologies for not replying sooner - I upgraded to version 2.9.0 and the problem went away
