我已经在ng update @angular/cli
命令的帮助下更新了我的angular-cli。在那之后,我得到了一个错误作为Could not determine single project for 'server' target
和下面的错误跟踪。
Could not determine a single project for the 'serve' target.
Error: Could not determine a single project for the 'serve' target.

这种行为让我很困惑。为了获得更多信息,我还在这里添加了我的package.json

在这里,我了解了为什么会发生这个错误。有人能帮我解决这个问题吗?

您是否遵循了更新过程的所有三个步骤?
更新通常遵循3个步骤,并将利用新的ng更新工具。
1)更新@angular/cli:
npm install -g @angular/cli
npm install @angular/cli
ng update @angular/cli
2)更新你的Angular框架包:
ng update @angular/core
3)更新其他依赖项

Angular 6添加了一个称为库的功能。我刚刚将我的通用项目从angular 4升级到6,这导致了上面的错误,在我的例子中,问题是下面的脚本:
"build:client-and-server-bundles": "ng build --prod && ng run project-name:server:production",
我通过将项目名称修改为脚本来修复它,如下所示:
"build:client-and-server-bundles": "ng build my-main-project-name --prod && ng run my-main-project-name:server:production",
现在,由于库的原因,您的ng build --prod
命令将更改为ng build --prod my-main-project-name
,您可以拥有多个项目,而不会让它们相互干扰。因此,您需要指定要构建的项目。
