问题如下：
warning MSB8004: Output Directory does not end with a trailing slash. This build instance will add the slash as it is required to allow proper evaluation of the Output Directory.
其实这个问题很简单，因为把英文翻译过来即可，输出路径结尾缺少一个反斜线。
解决方案：项目-项目属性-配置属性-常规-输出路径，现在的路径是下图这样的：
将其改为
即可。
问题如下：

大概错误是这个样子的，这个错误主要是在链接器的输出路径中，我是从一篇文章中看到的解决方案的，文章原地址如下：
解决方案：项目-项目属性-配置属性-链接器-常规-输出文件，原来是如下图的样子
点击<继承>的那个选项，得到结果如下图所示：
再次运行，成功！希望能对一些人
