Thanks again, I really appreciated your fast help! Okay, let´s see...
-
I followed your link and this lead mit to Shiny v1.3 known regressions and serious issues where i tried solution 1) by simply executing
remotes::install_github("rstudio/httpuv")in the console. But i didn´t change anything. Neither did selecting the "No proxy" option of my browser (firefox). -
Knitting a Markdown like here https://rmarkdown.rstudio.com/articles_intro.html worked just fine. I got rendered successfully in the browser. Same goes for the bookdown demo, you provided. Even though trying the "Build Book" Button form the "Build" Tab gives out the error Failed to compile bookdown-demo.tex. [...] Exited with status 1. ...but I assume that this has no relation to my actual problem?
-
Copy-pasting these commands seemed to work just fine. I got no errors.
So I guess, everything worked but didn´t point out the source of my problem? I am not 100% sure about the bookdown thing, since I´m not familiar with it (neither am I with proxy things and stuff like that, as you might have guessed by now). But like I said, it seemed to work just fine.
Sooo yeah... any ideas?
