Installing packages on Azure App Service via the startup command doesn't work.

Question

I'm trying to install two packages via the startup command, as shown in the screenshot.

However, I'm getting the following error messages in the console.

When I run the commands myself in the SSH it works fine.

Answer 1

I think the best solution for your problem is to deploy your application as a container: https://learn.microsoft.com/en-us/azure/app-service/quickstart-custom-container?tabs=dotnet&pivots=container-linux- vscode

This way you can customize the deployment and not try to modify the default installation of the App Service.

I fixed it by adding #!/bin/bash to to start of the start.sh file.
