Project build halts on: "Build delayed until Bower/npm packages finish restoring."

Question

In VS 2017, I created a new ASP.NET Core Web Application using the Angular template.

The project however does not run, it gets stuck on:

Build delayed until Bower/npm packages finish restoring.

I see that a background task is running, but this goes on for ever and doesn't make any progress.

Answer 1

I had a similar problem and I followed the below steps to get around it.

Disable Package restore:

1. Go to Tools -> Options -> Project and Solutions -> Web Package Management -> Package Restore.
2. Set False to 'Restore on Project Open' and 'Restore on Save'

After disabling, I opened a terminal and manually installed all the packages. I used Yarn to install the packages and faced no problems.

Visual Studio often halts during project builds because of timeouts. To get around that, I used the command yarn --network-timeout 60000.

Hope this helps!

Answer 2

i had a sort-a-like problem. This is what i did to solve it:

1. check the folder node_modules
2. on my pc it was empty
3. open the folder in a command prompt (with administrator privileges)
4. run "npm install", this will download all referenced node modules (see package.json) to your pc
5. then when you build in VS Studio,the bower delay is gone
