Failed to install

I tried installing manim, I think I did everything correctly, the requirements all installed well. When I tried to type in the ‘python -m pip install manimlib’, it ran for a while and gave a whole bunch of errors in red text.
Under that it said ‘failed to build opencv-Python’
I don’t know if you need to know some more about the error, when i looked trough it, it also said ‘could not find any instance of Visual Studio’

If you need any more information please let me know, because I really want to get this installed.
Thanks in advance!!
