How to install fibers package on Azure Web App

I cannot install an application using Vuetify on Azure Web App with a dependency on fibers package.

This package fails all the time, even when trying to install it alone (npm install fibers).

I run a simple Windows machine with a Node LTS stack. Although I tried with other stacks and even Linux with similar result.

The output message gives an alternative to build the package yourself but those guides require administrative privileges which is not possible to have on Azure Web App (to the best of my knowledge at least).

The package is quite popular which should be a wide problem on Azure developers, right?

Here the full output message from CMD (via Kudu):

In Azure webapp, the operating environment of node is more complicated. Azure generally only supports basic npm,npx and other global installation packages. I haven't encountered the rest for the time being. Because the environment is more complicated, I recommend using Linux runtime environment when creating webapp.

Steps to troubleshoot:

  1. Ensure that the local project is running normally and upload the code to github. If there is confidential information, remember to select the private mode when creating the project. For more detail, you can refer to my answer in this post which can tell you how to trouble shooting.

  2. Then use git continuous deployment to deploy the application to Azure.

Generally speaking, most of the deployment problems can be solved after this step. If not, you can view the specific error message in the Action.

Of course, if you are unwilling to use git deployment, you can use FTP to publish the local running code after building it, provided that git can be deployed and run successfully.
