Hello,

I try to use photon but it seems to have problem to launch. I'm on Windows 10, Rstudio 1.3.959 and R-4.0.0 (64 bits). In a default and working shiny app project with no specific packages needed, I call photon::photon_rstudioaddin(), the UI open and I chose the folder and click Build, then I get this error messages:

Warning in normalizePath(path.expand(path), winslash, mustWork) :
  path[1]="C:\Users\myname\Documents\R-projects\elektron/electron-quick-start": specified file impossible to find

The electron-quick-start folder is created but is empty and disappear when I close the UI window.

Do you have an idea of the problem ? Is there a setup I need to change ?

Thanks

Hey! An easy solution is to create the folder ``electron-quick-start'' manually and then run photon::photon_rstudioaddin()

That got past one error message, but then:

I have the same issue with the above error message, is there a known fix for this?

use setwd() in RStudio to set the working directory to the one containing electron-quick-start, this worked for me.

Mine errors here with the following error message: \app\electron-quick-start\R-Portable-Win\bin/install_packages.R Is it because of the forward slash that it is trying to look for in the install_packages part of the path.

my solution is to modify windows environment variables control panel/system/advanced system settings

  1. add an environment variable for R_USER 1.1 variable name: R_USER 1.2 click "Browse Directory" and select the path where the application is installed, then click "OK". for example: C:\Program Files\R\R-4.2.1

  2. modify the Path click "Browse Directory" and select the path where the application is installed, then click "OK". for example: C:\Program Files\R\R-4.2.1
