You are using pip version 10.0.1, however version 18.0 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

 

升级 python -m pip install --upgrade pip  升级成功后在重新安装 还是报错  所以尝试着安装twisted库 (https://www.lfd.uci.edu/~gohlke/pythonlibs/)

 

Twisted, an event-driven networking engine.

我的是 Twisted‑18.7.0‑cp36‑cp36m‑win_amd64.whl，你需要找到你的对应版本，然后下载。之后运行 pip install Twisted‑18.7.0‑cp36‑cp36m‑win_amd64.whl 成功后，在重新安装scrapy
