Can't load library after installing the package on Windows

[anthonypiccolo]

The following error is returned once I have installed the package and run library(prophet);

> library(prophet) Error: package or namespace load failed for ‘prophet’: .onLoad failed in loadNamespace() for 'prophet', details: call: fun(libname, pkgname) error: lazy-load database 'C:/Users/anthony/Documents/R/R-3.4.3/library/prophet/R/prophet.rdb' is corrupt In addition: Warning messages: 1: package ‘prophet’ was built under R version 3.4.4 2: In fun(libname, pkgname) : internal error -3 in R_decompress1

Any help would be greatly appreciated!

I'm not sure what has happened here, but I wonder if the warning of prophet being built in 3.4.4 but being run in 3.4.3. Could you try installing from github:

devtools::install_github('facebook/prophet', subdir='R', ref='master')

This error takes place first;

No C++ compiler found, so the following will probably not work. See https://github.com/stan-dev/rstan/wiki/Installing-RStan-on-Windows#toolchain

Resolved this issue now, needed to get rstan installed, it still doesn't work UNLESS I load rstan first. If I haven't loaded rstan it returns this when I try and run the prophet library;

Interested to know why this would be occurring?

At least I can use prophet now!

[bletham]

Those messages there all looks like warnings, I'm wondering if it actually did load? could you post

library(prophet)
sessionInfo()

[anthonypiccolo]

It's seemingly attached.

other attached packages: [1] prophet_0.2.1 Rcpp_0.12.16

[bletham]

Great, then I think those were just warnings and I'd expect it to work.

@divya074 that error is for a different package, I think you will have more success asking at https://github.com/vishnubob/python-midi
