我如何解決「Microsoft.AspNetCore.NodeServices.HostingModels.NodeInvocationException」

Question

我剛剛創造了新的ASP.NET Core Web Application使用預定義模板e.g`文件>新建>項目> Asp.Net核心Web應用程序」。

我選擇.NET Core 2.0有角模板。 我使用VS 2017 安裝在我的機器上的節點版本是4.2.2 NPM版本2.14.7

當我跑我得到異常

Answer 1

的原因我看這個問題基本上是你使用舊版本的節點和NPM。就像你說的"The node version installed on my machine is 4.2.2 NPM version is 2.14.7"

您需要更新他們 Node: 6.11.2 NPM: 3.10.10.

然後問題應固定。
