Question

我最近发现scrapy是一个很好的抓取库，所以我试着在我的机器上安装scrapy，但是当我试着pip install scrapy它安装了一段时间并把这个错误扔给我..

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

和

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

    ----------------------------------------
Command "d:\pycharmprojects\environments\scrapyenv\scripts\python.exe -u -c "import setuptools, tokenize;__file__='C:\\Users\\User\\AppData\\Local\\Temp\\pip-build-arbeqlly\\Twisted\\setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record C:\Users\User\AppData\Local\Temp\pip-jdj93131-record\install-record.txt --single-version-externally-managed --compile --install-headers d:\pycharmprojects\environments\scrapyenv\include\site\python3.5\Twisted" failed with error code 1 in C:\Users\User\AppData\Local\Temp\pip-build-arbeqlly\Twisted\

之后我去了this网站并安装了python的工具..

但在安装结束时得到这个：

任何帮助？

Answer 1

Scrapy文档现在建议使用Conda进行Windows安装：

https://doc.scrapy.org/en/latest/intro/install.html#windows

Answer 2

如果您没有安装Windows SDK，则会出现此错误。

使用Build Tools或Visual Studio进行编译时，通常需要C ++编译器和Windows SDK。在构建工具中，有一个＆＃34; Custom＆＃34;安装选项，使您可以选择安装C ++和Windows SDK。在Visual Studio中，您必须修改安装以安装Windows SDK。

我相信您需要与您正在使用的平台相对应的SDK（Windows 10 SDK for Windows 10等）。
