Azure DevOps上带powershell脚本的角度构建错误

我在azure devops构建管道中准备了一个powershell脚本来创建工件，但是当我启动构建队列时，我得到一个错误，如下所示

build命令需要在角度项目中运行，但是 找不到项目定义

谁能帮帮我吗

Powershell脚本：

npm install

npm install -g typescript

npm install -g @angular/cli

ng build --configuration=production

这是powershell脚本的全部结果：

npm install

npm install -g typescript

npm install -g @angular/cli

ng build --configuration=production

正如错误所说，您试图运行

ng build

而不是在项目文件夹中

您需要先运行

cd path/to/project文件夹

---

另一个选项，在Azure DevOps PowerShell任务中有一个指定“工作目录”的选项，因此在那里输入项目路径。

在

ng构建之前

添加

cd路径/to/angular/project

您能否确认您的存储库在构建过程中被克隆？angular cli项目的常见构建日志：1）准备作业2）初始化作业3）签出4）使用节点10.15.3 5）npm安装包6）npm构建问题是angular项目的文件路径，如Shayki Abramczyk所说，他对我的问题发表了评论。当我将我的分支推到Azure Devops时，他们创建了一个带有项目名称的目录，但我认为Powershell脚本可以在angular项目中工作，但我错了。谢谢，太好了！我还添加了它作为答案：）
