如何解决错误“无法找到 local.config.user 文件。确保您已运行 'build.cmd local'”

Question

我正在尝试在本地主机上运行此测试，但它一直抛出错误“无法找到 local.config.user 文件。请确保您已运行 'build.cmd local'”

那么如何找到 local.config.user 文件呢？或者如何在本地运行 build.cmd ？请尝试查看下面的代码

您好，先生，谢谢您的帮助。我试过“Build.cmd build”和“Build.cmd local”，它给了我这个错误。

通常，在 Visual Studio 解决方案的根文件夹中，您应该有一个 build.cmd 文件。

您需要以管理员身份运行 Developer Command Prompt for VS2015（或安装其他版本的 Visual Studio，使用开始菜单中的 Windows 搜索）并将目录 (cd [directory with solution]) 更改为上述解决方案的根文件夹，然后键入并通过单击 Enter 运行 build.cmd local。
