"bower install" exited with code 9009. in ASP.NET core application

Question

I am facing an issue of

The command "bower install" exited with code 9009

while publishing the ASP.NET core-MVC application with entity framework. I am using VS-2017.

I got many suggestions in your portal of downloading node.js globally, but as I am very new to this system I don't know how to do so. Or if there is any other solution for that please let me know.

Answer 1

1. Make sure to install Node.js.

2. Install bower globally by executing the following command in cmd:

   npm install -g bower

3. Close Visual Studio, then open it and try again.

Answer 2

Also worked for me by removing the code below in the project file.

<Target Name="PrepublishScript" BeforeTargets="PrepareForPublish">
<Exec Command="bower install" />
<Exec Command="dotnet bundle" />

However it did cause a couple of typescript issues with duplicate method names, add the below code to the tsconfig.json file

"exclude": [ "obj" ]

Answer 3

What worked for me.

I went to project file (in VS-2017 Explorer you can right-click it and edit it)

Then I deleted (or commented) the Target node

  <Target Name="PrepublishScript" BeforeTargets="PrepareForPublish">
    <Exec Command="bower install" />
    <Exec Command="dotnet bundle" />
  </Target>

Everything was fine without installing anything else.
