python3 使用pip 安裝scrapy報錯
直接使用pip3 install scrapy會報很多錯誤,所以試試以下步驟。
(1)
https://www.lfd.uci.edu/~gohlke/pythonlibs/
在這個python第三方庫裡下載三個包:分別是lxml,twisted,scrapy。【按照自己的電腦和Python版本下載相應的包】
(2)
cd 到放這三個包的資料夾下,依次pip3 install 上述三個.whl檔案。
例如:
pip3 install Twisted-17.9.0-cp36-cp36m-win_amd64.whl
pip3 install Scrapy-1.4.0-py2.py3-none-any.whl
(3)
全部安裝完後,直接在命令列輸入scrapy,看是否出現以下提示,如果出現則說明安裝成功。如果不出現,執行步驟(4)
