ASP.NET MVC 3 - 错误添加使用MvcScaffolding模板

Question

我试图与指定的以下模板添加一个新的控制器，新的控制器：

MvcScaffolding：控制器，具有读/写操作和视图，使用存储库

这在以前的项目工作，但现在我越来越从包管理器的输出如下：

上发生了什么任何想法？

Answer 1

当您安装T4Scaffolding包时，它会在powershell主机中注册它的程序集和包含的cmdlet。出于某种原因，它可能会从两个不同的位置加载T4Scaffolding软件包，并且由于powershell无法确定要执行哪个软件包cmdlet，因此会“解析为不明确的cmdlet名称”错误。 正如我看到你执行“C：\ Development \ packages \ MvcScaffolding.1.0.0 \ tools \ RazorView \ MvcScaffolding.RazorView.ps1”中的模板，这看起来像是一个全局包，如果你的解决方案中本地安装了MvcsScaffolding - （ SolutionFolder）\ p​​ackages \ MvcScaffolding.1.0.0 powershell可能会加载这两个包。

如果您从Visual Studio生成控制器 - >项目 - >右键 - >生成控制器，它将工作，因为Visual Studio插入控制器生成不使用T4Scaffolding powershell命令。
