Cannot install r-languageserver in treesitter (Neovim) when R-CoprManager installed

[py9mrg]

Hello,

As per title, when I have R-CoprManager installed I cannot install r-languageserver in treesitter (using Neovim, but I guess it's the same for other editors).

In my case (here using LazyVim, but I also tried with the Quarto kickstarter) I get the following error:

Doing some searching, dbus issues seem to be related to bspm not being installed in R. If I manually do it and then add bspm::enable() to .Rprofile it doesn't help so I'm at a bit of a loss?

My current solution is simply to uninstall R-CoprManager while installing r-languageserver in treesitter, and then reinstalling it. But I don't know if this "solution" will break something later.

CoprManager is a copy of bspm adapted to this project, so you should not install bspm on top of it. Try the following:

1. Uninstall all copies of bspm, remove all references to it from your Rprofile, etc.
2. In a fresh R session, run CoprManager::disable(), then install r-languageserver, then CoprManager::enable() again (or simply restart your R session).

Hello,

The above error quoted above was from before I installed bspm - I only tried that as a solution after having the problem. It was also output from trying to install the r-languageserver lsp in Neovim, not the languageserver package in R.

Using CoprManager::disable() does not seem to fix the problem. Nor does installing languageserver in R. Remember, the above error is within Neovim not R. The only way I can solve this is with uninstalling R-CoprManager, then installing r-language server in Neovim - and then reinstalling R-CoprManager.

I have no idea why this is, but it doesn't seem to have an R-side solution.

The above error quoted above was from before I installed bspm - I only tried that as a solution after having the problem.

I know, I was explaining the relationship between CoprManager and bspm, and pointing out that any solution would require first to revert the installation of bspm on top of CoprManager.

It was also output from trying to install the r-languageserver lsp in Neovim, not the languageserver package in R.

r-languageserver does install languageserver to an isolated library locatio, as per their README, and also your output above. So there is an R session involved at some point.

Using CoprManager::disable() does not seem to fix the problem.

Well, it would, if you were able to inject that into the R session (per my comment above) that r-languageserver spawns. One quick and dirty workaround would be to put that into your user .Rprofile, run r-languageserver's installation, then remove that from your .Rprofile. But this should be addressed in the installer, see below.

I have no idea why this is, but it doesn't seem to have an R-side solution.

This is a bug in r-languageserver's installation instructions. Given that they are basically building a separate standalone R library, they should add --vanilla to their instructions, to avoid this kind of unwanted interactions with other components:

$ R --vanilla --slave -f src/install.r <lib_loc> <ref>

I recommend bringing this upstream to r-languageserver and neovim's plugin manager.

Brilliant, thank you. And will do.
