Failed to activate rbenv environment

[kadru]

Hi, I just trying to use this extension but it fails to activate:

Failed to activate rbenv environment: Command failed: /bin/bash -lic 'rbenv exec ruby --disable-gems -rjson -e "printf(%{RUBY_ENV_ACTIVATE%sRUBY_ENV_ACTIVATE}, JSON.dump(ENV.to_h))"' bash: no se puede establecer el grupo de proceso de terminal (11835): Función ioctl no apropiada para el dispositivo bash: no hay control de trabajos en este intérprete de ordenes No se ha encontrado la orden «rbenv», pero se puede instalar con: sudo apt install rbenv

It seems the extension cannot find rbenv but I can run the command that the extension is trying to run and is running without errors inside the vscode terminal.

I'm using:
vscode 1.76.2
ruby lsp extension 0.2.3
ruby 2.7.7
rbenv 1.1.2-40-g62d7798
ubuntu 20.04

Hey. Is rbenv loaded in your ~/.bashrc?

[kadru]

Yes, is loaded with eval "$(rbenv init -)"

[vinistock]

Do you have another configuration file such as ~/.profile? If you do, can you try activating rbenv there? I want to understand if maybe the interactive bash mode is not loading ~/.bashrc by default.

Just wanted to add that I'm running on 22.04 and have the same issue.

I had eval "$(~/.rbenv/bin/rbenv init - bash)" in my ~/.bashrc.

I followed you suggestions in the previous reply and duplicated it in ~/.bash_profile. The extension does seem to start up and does not error in the same place in that case.

Generally, I don't believe .bash_profile is really all that used on Ubuntu and the recommendation is to avoid its use so that's not really ideal workaround.

I thought using the -i flag for an interactive bash shell would load ~/.bashrc. Is there a way to tell bash to load it?

[wwahammy]

So a bit of info: If I delete ~/.bash_profile, then the project install works perfectly. Having ~/.bash_profile on Ubuntu is not recommended but a tool (pipx) automatically added it last week.

I don't know whether the best way to handle this for the extension but at the very least, it would be nice if this issue could be detected so the user would know the problem.

I can't help on whether there's a better way to tell bash to load ~/.bashrc though, this is not my area of expertise 😄

This worked for me as well.

Weirdly all was working fine until i removed previous ruby version and installed 3.3.1. After that it kept showing me

Automatic Ruby environment activation with rbenv failed: Command failed: rbenv exec ruby -W0 -rjson -e STDERR.printenv: ENV.toh,jeet:!!defined?(RubyVM::YJIT),version:RUBY VERSION}.to_json) /bin/sh: 1: rbenv: not found

My system has ~/.bash_profile and vscode ruby-lsp was working along with ~/.bash_profile until i updated ruby.
Deleting ~/.bash_profile is what made it worked.

Weird that it was working earlier and ruby version change caused issues.

vscode 1.89.1
vscode-ruby-lsp-v0.5.21
ruby 3.3.1
rbenv 1.2.0-89-gac02022
ubuntu 24.04
