Azure functions node error when doing npm start

Question

I am trying to run my azure functions locally by doing npm start or even the simple func start.

It was working perfectly until today when the following error started coming:

The func.deps.json file is here: C:\Program Files\Microsoft\Azure Functions Core Tools and it has the dependency below.

I don't even use this and don't know what it is "Error: An assembly specified in the application dependencies manifest (func.deps.json) was not found: package: 'Marklio.Metadata', version: '1.2.20-beta' path: 'lib/netstandard2.0/Marklio.Metadata.dll' npm "

xxx-api@0.0.1 build:docs C:\Code\xxxx-api
> tsc --sourcemap --lib es2017 src/_doc/index.ts --outDir doc && node doc/index.js

Error:

  An assembly specified in the application dependencies manifest (func.deps.json) was not found:
    package: 'Marklio.Metadata', version: '1.2.20-beta'

Answer 1

Remove all references of this Marklio dependency from the func.deps.json and run this: npm i -g azure-functions-core-tools@3 --unsafe-perm true

Answer 2

I found that if you go to the path specified after the error message, and delete the Releases folder and run Visual Studio, it will redownload everything you need and it will run fine.
