Re: Error running GNU radio V. 3.8.1 on windows 10

[Geof Nieboer]

This appears to be issue related to the one here:  https://stackoverflow.com/questions/36003023/json-dump-failing-with-must-be-unicode-not-str-typeerror/36003774, and probably caused because this Win10 version is the last with py2.7 integrated.

I haven't run into this error myself, so I'm not sure why it's happening for you.

I see three options for you:

1- Figure out what unicode characters were being used that caused python to want to save it as unicode and don't use those (possible temp workaround)

2- Modify cache.py manually using the information on the SO link so it's compatible.

3- Wait until I release a Python 3 version of GR 3.8 for Win10.  This is the next task in my list, but I make no promises as to timelines.  In the meantime, you could try 3.8.0 or 3.7.x versions.

Here is the error log when im trying to start the application:

Anyone know how i can fix this error, or why im getting it in the first place? This is a fresh install of 3.8.1.
