python - 安装Scrapy时出错报错: Microsoft Visual C++ 14. 0 is required

Question

我发现 scrapy 是一个很棒的抓取工具，所以我尝试在我的机器上安装 scrapy，但是当我尝试执行 pip install scrapy 时，它安装了一段时间并向我抛出这个错误。 .

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

我尝试在虚拟环境中安装它，但问题仍然存在。

编辑:这是我在错误后得到的..

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

有什么帮助吗？

使用 Conda 安装

如果你有conda 使用:conda install -c anaconda scrapy

或者

使用pip安装
