在Windows中安裝Scrapy時遇到問題

Question

我在Windows（64位）中使用Scrapy安裝。

當發現vcvarsall.bat時顯示錯誤時，我卡住了：

Answer 1

解決丟失的vcvarsall.bat的另一種方法是為Python 2.7安裝Microsoft Visual C ++編譯器http://www.microsoft.com/zh-cn/download/details.aspx?id=44266

當您收到該錯誤時，您可能只想為其找到Windows安裝程序，它將包含丟失的文件。 http://www.secdev.org/projects/scapy/files/

這是錯誤的解釋。 http://slacy.com/blog/2010/09/python-unable-to-find-vcvarsall-bat/

嘗試：

easy_install scrapy 

這對我有效，沒有任何錯誤。
