安裝scrapy時(shí)報(bào)以下錯(cuò)誤

  -----------------------------------
  Failed building wheel for Twisted
···
    error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

首先在https://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted這個(gè)網(wǎng)址上找到twisted,點(diǎn)擊進(jìn)入后就會(huì)出現(xiàn)你要下載的twisted版本

找到對(duì)應(yīng)的版本就可以，cp27/34/35/36/37代表python版本，win32是32位的，win_amd64是64位

下載好之后進(jìn)入到下載twisted的文件夾，pip install 文件名

出現(xiàn)Successfully installed Twisted-18.9.0表示安裝成功
再pip install scrapy就可以安裝成功了
