R Markdown Bibliography Error 83

[Sandmann]

Hey community,
it sounds very silly but I'm just failing to get the bibliography running in R Markdown =(
I just created a sample file:

---
title: "test"
author: "author"
date: "6/25/2020"
output:
  word_document: default
  pdf_document: default
  html_document:
    df_print: paged
link-citations: yes
bibliography: test.bib
---


# Einleitung

dasd
nocite: '@*'

# References

I always get the Error:

Error running filter pandoc-citeproc: Could not find executable pandoc-citeproc Error: pandoc document conversion failed with error 83

My test.bib file is in the same direction and consists of the following code:

---
@Manual{anderson2015,
  title = {Exhumation by debris flows in the 2013 Colorado Front Range storm},
  author = { S.W. Anderson and S.P. Anderson and R.S Anderson}
}

Can you help me?
