In Windows, you have two ways to use the command:
- 1. If pylauncher is selected when you installed Python, you can directly use "python" command in your Command Prompt or PowerShell
- 2. You can also go to python's install location where python.exe is located, use that as your working directory and launch that executable to use the command.
I've added a heads-up because of my own tests in Windows, btcrecover and certain versions of python that couldn't compile a mandatory requirement for using seedrecover on ETH seed phrase.
Depending on your set-up and installed requirements, you may encounter that error.
First, can you test if python is installed correctly in your system?
Since it's on Windows, try to enter this command in your command prompt and see it it'll return with the installed version:
If nothing works, you need to do option2 which requires absolute paths.
