I installed Python, but I still can't run the program.
Hello,
There's a guide available here: https://github.com/DevilXD/TwitchDropsMiner/wiki/Setting-up-the-environment,-building-and-running
The guide explains how to install Python and Git, both of which are required to be able to create a virtual environment for this project to be installed into.
If you're looking for Git installation specifically, it can be found here: https://github.com/DevilXD/TwitchDropsMiner/wiki/Git-Installation
I installed git and python, but why does it give me an installation error when the "requirements" file is already in the folder?
The message higher up says that Python wasn't found, so either you've installed it wrong, or you haven't restarted your computer after the installation. If it won't work after a restart either, you'll need to uninstall Python, and then install it again by following the guide too: https://github.com/DevilXD/TwitchDropsMiner/wiki/Python-Installation
