【环境配置】出现：Microsoft Visual C++ 14.0 is required 的解决方案_microsoft visual c++ 14.0 is required. get it with

由于windows开发经常出现这个问题，真是令人讨厌，于是得想个法子，干他娘的一炮，以绝后患，二营长，老子的意大利炮呢！

第一种情况

以安装scrapy为例：

如：pip install scrapy 时出现：

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

解决办法

1. 安装 Microsoft visual c++ 14.0

2. 如果出现了.Net framework版本过低，小于4.5的最低版本要求：

[如果没出现这个问题，跳过这一步]

• 重新安装 .Net framework 更高的版本：

• 再安装Microsoft visual c++ 14.0，

3. 启动电脑，再安装scrapy

pip install scrapy

第二种情况

如安装pip install cnstd为例，出现：

  Building wheel for Polygon3 (pyproject.toml) ... error

      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for Polygon3
