rstudio not recognizing orca cmd tools

[dschneiderch]

i'm trying to download a figure from a rshiny app that displays a plotly figure. rstudio throws an error

Warning: Error in : The orca command-line utility is required for this functionality.
Please follow the installation instructions here -- https://github.com/plotly/orca#installation
  [No stack trace available]

but orca is in the path. see image

Im running WIndows 10 with the latest Rstudio v1.1.463. the app developer suggested I try a different plotly version so after I tried plotly on cran (plotly_4.8.0) I got the same result with plotly from devtools::install_github("ropensci/plotly") plotly_4.8.0.9000

any suggestions?

Hi @dschneiderch ,

Thanks for reaching out, can you try the suggestions in #120 (comment)?

oddly enough i opened everything up (computer was shut down over the weekend) and it worked*, but I will keep that in mind. Thanks.

• it worked as expected ( download of plot.png) from an external viewer (browser) but when using the internal rstudio viewer i get a file called download_plot without an extension. renaming it to png allows it to open. i believe the internal R function inside the app is called download_plot if that helps. my understanding is this is a known issue though.
