ASP.NET MVC 3 - 錯誤添加使用MvcScaffolding模板

Question

我試圖與指定的以下模板添加一個新的控制器，新的控制器：

MvcScaffolding：控制器，具有讀/寫操作和視圖，使用存儲庫

這在以前的項目工作，但現在我越來越從包管理器的輸出如下：

上發生了什麼任何想法？

Answer 1

當您安裝T4Scaffolding包時，它會在powershell主機中註冊它的程序集和包含的cmdlet。出於某種原因，它可能會從兩個不同的位置加載T4Scaffolding軟件包，並且由於powershell無法確定要執行哪個軟件包cmdlet，因此會「解析爲不明確的cmdlet名稱」錯誤。 正如我看到你執行「C：\ Development \ packages \ MvcScaffolding.1.0.0 \ tools \ RazorView \ MvcScaffolding.RazorView.ps1」中的模板，這看起來像是一個全局包，如果你的解決方案中本地安裝了MvcsScaffolding - （ SolutionFolder）\ p​​ackages \ MvcScaffolding.1.0.0 powershell可能會加載這兩個包。

如果您從Visual Studio生成控制器 - >項目 - >右鍵 - >生成控制器，它將工作，因爲Visual Studio插入控制器生成不使用T4Scaffolding powershell命令。
