Visual Studio 2017 .NET Core 2.1 Angular 上的“npm run build -- --prod”錯誤

Question

我需要幫助，我已經在基於 .Net Core 2.1 的 Angular 上做了一個項目。 因此，當我嘗試發布 VS 時，返回此錯誤：

所以錯誤是：

所以，我遵循了這個解決方案： 命令“npm run build -- --prod”退出，出現代碼 1 錯誤但沒有成功，我沒有找到這個： npm run build -- --prod on my .angular-cli.json我該如何解決這個問題？ 謝謝

Answer 1

我遇到了與您相同的問題，我設法通過以下方式解決了該問題：

編輯您的.csproj文件： Right click on you project -選擇Edit ____.csproj

替換為：

<Exec WorkingDirectory="$(SpaRoot)" Command="npm run build -- --prod" />
<Exec WorkingDirectory="$(SpaRoot)" Command="npm run build:ssr -- --prod" Condition=" '$(BuildServerSideRenderer)' == 'true' " />

有了這個：

<Exec WorkingDirectory="$(SpaRoot)" Command="npm run build --prod" />
<Exec WorkingDirectory="$(SpaRoot)" Command="npm run build:ssr --prod" Condition=" '$(BuildServerSideRenderer)' == 'true' " />

基本上，命令npm run build -- --prod應該是npm run build --prod

Answer 2

從 .csproj 文件中刪除 -- 后，它不起作用。 當我們在本地運行時，即使此命令也能正常工作，但在將代碼部署為時遇到問題 - 錯誤 MSB3073：命令“npm run build --prod”以代碼 3 退出。
