So the key problem is to install twisted first.

You can find this on the very website:https://www.lfd.uci.edu/~gohlke/pythonlibs/

I choose:Twisted‑17.9.0‑cp36‑cp36m‑win_amd64.whl

Then I follow this tutotial to install twisted:

(1)to enter the file of python36(or 3x), and run command:"python3 -m pip install wheel"

(2)to move the file "Twisted‑17.9.0‑cp36‑cp36m‑win_amd64.whl" to the very place:

C:\Users\XXXXX\AppData\Local\Programs\Python\Python36\Scripts

(3)run command: "python3 -m pip install Twisted‑17.9.0‑cp36‑cp36m‑win_amd64.whl"

(4)run command: "python3 -m pip install scrapy"

That's all, thx.
