使用Powershell脚本在Azure DevOps上进行角度生成错误

Question

I prepared a powershell script in azure devops build pipeline to create an artifact, but when I start build queue, I get an error which is below.

The build command requires to be run in an Angular project, but a project definition could not be found.

Can someone help me please.

Powershell script:

npm install

npm install -g typescript

npm install -g @angular/cli

ng build --configuration=production

This is all the result of powershell script:

As the error said, you try to run ng build not in the project folder.

You need to run cd path/to/project-folder before.

Another option, in the Azure DevOps PowerShell task there is a option to specify "Working Directory" so enter there the project path.
