SyntaxError: invalid syntax

Fresh install on Ubuntu 16.04 following steps on the Docs,

Does anyone have any way around this?

Try editing the file "/home/mike/.local/lib/python3.5/site-packages/viper/core/ui/cmd/update-modules.py" at line 29 with

self.log("info", 'Module path: {dot_viper_modules}')

The syntax is correct. You need Python 3.6 to run this properly, but you are still on Python 3.5.

VenturiniGiacomo commented 3 years ago

What means "f"? in original line 29? self.log("info", f'Module path: {dot_viper_modules}')

botherder commented 3 years ago

It's Python 3.6+ new string formatting standard.
