想跟随油管某视频复现强化学习方法玩超级马里奥的过程，结果在在Anaconda3虚拟环境中用pip安装nes_py时一直报错，报错信息如下：

问题描述

从上面的报错信息可以得知，我们的问题在于没有找到wheel，说明本地没有相关配置。而最后一行也告诉我们提示：不是pip的问题，而是上述提到的包（nes）的问题，所以看上面的报错信息找原因。

原因分析：

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

发现上述一行报错信息：说明我们本地缺少msvc的组件。

原来是我前段时间为了给C盘瘦身，把VS给全部清理了，因为目前主要精力在Python上。

那这就好办了，去他给的官网下载就是了。

解决方案：

下载官网文件

https://download.visualstudio.microsoft.com/download/pr/0502e0d3-64a5-4bb8-b049-6bcbea5ed247/d7293c5775ad824c05ee99d071d5262da3e7653d39f3ba8a28fb2917af7c041a/vs_BuildTools.exe

下载完成以后是VS Installer，这次我们修改安装路径，不要放C盘了，我们在D盘新建文件夹叫Workspace，把其余路径原封不动搞进去

刚刚安装忘记截图了，总之就是这个路径，vs文件夹下还有个package文件夹，一共两个路径。

最后点击安装就完成了！ 

注意一定要勾选C++桌面开发 

解决结果：

安装依赖以后成功安装
