原因分析：PyCurl 安装错误，需要安装 PyCurl 库（PyCurl 是一个Python接口，是多协议文件传输库的 libcurl。类似于urllib Python模块，PyCurl 可以用来从Python程序获取 URL 所标识的对象）

解决方法：访问 https://www.lfd.uci.edu/~gohlke/pythonlibs/#pycurl ，下载对应的 wheel 文件，比如我是 Windows 10 64位，Python 3.6.5，则下载 pycurl‑7.43.0.3‑cp36‑cp36m‑win_amd64.whl，然后使用命令 pip install pycurl‑7.43.0.3‑cp36‑cp36m‑win_amd64.whl 进行安装即可，PyCurl 安装完成，再次执行 pip install pyspider 即可成功安装 pyspider
