This is my current try, but I don't know why it cannot put in the right position:
Graphics[AxisObject[
Line[Table[{ Cos[t], Sin[t]}, {t, 0, 2 Pi, 0.01}]],
TickPositions -> {10}, TickLabels -> {Range[0, 7 Pi/4, Pi/4]}]]
Actually, I think TickPositions -> {9}
should serve me. Is it a bug or I have missed something?
