![在Windows上使用Python安裝scrapy時出現OpenSSL問題](https://rvso.com/image/1395281/%E5%9C%A8Windows%E4%B8%8A%E4%BD%BF%E7%94%A8Python%E5%AE%89%E8%A3%9Dscrapy%E6%99%82%E5%87%BA%E7%8F%BEOpenSSL%E5%95%8F%E9%A1%8C.png)
我已切換到 32 位元安裝程式Python Scrapy
(在無法安裝 64 位元安裝程式以使 scrapy 正常工作之後)。按照提到的步驟操作這裡。
easy_install
這是我運行on時的日誌scrapy

我已經嘗試過每一個帖子的答案或教程。我使用的是 64 位元 Windows 機器
答案1
我有完全相同的問題,但在 Windows XP 上。
若要解決 openssl/asn1.h no such file 問題,請檢查您的變數LIB
和INCLUDE
系統變數。
在 Windows XP 中,您可以使用下列命令從 CMD 提示字元視窗執行此操作:
SET LIB
SET INCLUDE
它們應該包含 OpenSSL 目錄的 lib 和 include 資料夾。在我的機器上:
SET LIB C:\OpenSSL-win32\lib;etc;etc;etc
SET INCLUDE C:\OpenSSL-win32\include;etc;etc
您可以像這樣新增到系統變數:
SET LIB=C:\OPenSSL-win32\lib;%LIB%
恐怕這無法解決訪問被拒絕的問題。
答案2
如果以後有人遇到此主題:
我在 Python 2.7 上使用 easy_install 安裝 Scrapy 時遇到了難以置信的困難。尤其是加密模組無法安裝。
我使用以下位置找到的資訊安裝了 piphttps://stackoverflow.com/questions/4750806/how-to-install-pip-on-windows
後來簡單的pip install scrapy
我就開始做生意了。
