I tried everything related to this error but couldn’t find solution, and also checked the file - 3.6.3/library/StanHeaders/include/stan/math/prim/mat/fun/Eigen.hpp

Found this file at same location, please help someone

You temporarily need

```
install.packages(
"https://win-builder.r-project.org/5yFs1HoUI204/StanHeaders_2.21.0-6.zip",
repos = NULL, type = "win.binary"
)

```

I’m having the same issue with `brms`,

I have:

```R
packageVersion("brms")
#> [1] ‘2.13.3’
packageVersion("rstan")
#> [1] ‘2.21.1’
packageVersion("StanHeaders")
#> [1] ‘2.21.0.5’

```

I was unable to run this:

Failing with:

```no-highlight

We can update the StanHeaders but unfortunately the Makevars handling in rstan is messed up right now.

@mattansb Do the updated links in [Rstan on Windows](https://discourse.mc-stan.org/t/rstan-on-windows/16673) work for you?
