错误：apriltag 的构建轮失败

Question

I'm trying to pip install apriltag, but am getting the error ERROR: Failed building wheel for apriltag . I've seen several posts on failure building wheel but can't seem to find one that gives a solution to my particular problem. I do have 'wheel' installed. I also have opencv already installed and working via pip install opencv-contrib-python

Here is the entire output when I do pip install apriltag

Answer 1

Looking through your error log, your actual error is: "invalid numeric argument '/Wsign-compare'"

...which makes this question a duplicate of invalid numeric argument '/Wsign-compare': Can't install pip package or build corresponding library on Windows
