从这里得到裁判

之前,请确保您位于终端的项目目录中 正在运行“ng serve”

假设您的文件夹结构如下所示:

|-Documents
|---my_projects
|-----angular_project
例如,确保您的终端位于“angular_项目”中。i、 e

username@PC_NAME:~/Documents/my_projects/angular_project$ ng serve

你能发布你的angular.json文件吗?我只得到angular-cli.json(显示在这里)。不是angular.json。我是这样运行的。但只有npm运行工作。ng serve不起作用。能否共享您的package.json?这是如何配置npm脚本的问题。
|-Documents
|---my_projects
|-----angular_project
username@PC_NAME:~/Documents/my_projects/angular_project$ ng serve
