问题描述

我正在Visual Studio 2017中开发一个Asp.Net Core 2和Angular 5项目.

I'm developing an Asp.Net Core 2 and Angular 5 project in visual studio 2017.

当我要发布项目时，错误"错误代码窗口中显示命令"npm run build---prod"，代码为1 ".
我在ASP.NET Core 2 Angular模板中使用 Angular CLI创建了项目 链接，一切都很好，项目可以正常运行和发布.
过了一会儿，我不知道到底发生了什么，导致该项目无法发布.

When I'm going to publish my project then the error 'The command "npm run build -- --prod" exited with code 1' show in error list window.
I created the project with Angular CLI in ASP.NET Core 2 Angular template link and everything was fine and the project run and publish correctly.
After a while, I don't know what exactly happens that cause the project doesn't publish.

推荐答案

只要有错误，请执行以下任一选项

Perform any of the following options as long as there is an error

1. 用于将参数传递给构建命令:

1. For passing an argument to build command:

在.csproj文件中将"npm run build---prod"更改为"npm run build --prod"

打开ClientApp文件夹，并使用以下CMD命令更新项目angular-cli:

Open ClientApp folder and Update project angular-cli with this CMD command:

npm install --save-dev @ angular/cli @ latest

从以下位置更新Visual Studio NodeJS和npm:

Update visual studio NodeJS and npm from:

Tools > Options > Projects and Solutions > Web Package Management > External Web Tools

Tools > Options > Projects and Solutions > Web Package Management > External Web Tools

如果您的环境路径中未安装NodeJS和npm，则将NodeJS和npm文件夹添加到列表顶部，否则将$(path)移到列表顶部

If NodeJS and npm aren't installed on your environment path Add NodeJS and npm folder to the top of the list else move $(path) to the top of the list
