angular - Angular CLI 停止创建新项目而没有任何错误

问题描述

我正在尝试使用 Angular cli 创建一个新项目，但它看起来像是卡在提取中并且不会产生任何错误：

D:\Angular6Sample\Angular6Sample>ng new angular6web --skip-git --skip-tests
CREATE angular6web/angular.json (4127 bytes)
...
CREATE angular6web/e2e/src/app.e2e-spec.ts (307 bytes)
CREATE angular6web/e2e/src/app.po.ts (208 bytes)
[            ......] \ extract:@angular/compiler: sill extract @angular/compiler@^6.1.0 extracted to D:\Angular6Sample\Angular6Sample\angular6web\node_modules\.stagin

我打开了一个新的 cmd 窗口并尝试创建一个新项目，它告诉我它已经存在：

D:\Angular6Sample\Angular6Sample>ng new angular6web --skip-git --skip-tests
ERROR! angular6web/angular.json already exists.
...
ERROR! angular6web/e2e/src/app.po.ts already exists.
The Schematic workflow failed. See above.

D:\Angular6Sample\Angular6Sample>

所以我认为我的项目已经创建，但在第一个 cmd 窗口中未能正确响应，所以我尝试构建它：

D:\Angular6Sample\Angular6Sample>cd angular6web

D:\Angular6Sample\Angular6Sample\angular6web>ng build
Could not find module "@angular-devkit/build-angular" from "D:\\Angular6Sample\\Angular6Sample\\angular6web".

D:\Angular6Sample\Angular6Sample\angular6web>

我错过了什么？
