Package does not install

[zrahmani]

Hello,

I cannot install psycho on my linux machine (Ubuntu 18.4). I get various error messages, such as
"try removing lock00-rstanam" or "lazy loading failed for package psycho".
or RStudio crashes on the attempt to install it.

I have tried to install it in the console, in RStudio (via the click-option, install.packages, and install.packages(..., INSTALL_opts = c('--no-lock')).

Do you know what I can do about it? Thank you very much

@zrahmani This error seems to be unfortunately related to the rstanarm package installation... I think you should aim at installing it first (I remember seeing threads and answers related to rstanarm installation issues).
