Notes

• It detects I'm using Fish ✅
• It doesn't find rvm but running the same command from the terminal works fine
• your 131072x1 screen size is bogus. expect trouble - I have no idea about this but it doesn't sound good 🙃
• I'm very open to this being a me problem but I'd love if someone could take a look :)

Maybe this is similar to a problem I recently experienced (#2369 ). The cause was the default terminal in VSCode not being compatible.

In fish shell, you can try changing the terminal size with the mouse or adjust the shell variables in the ~/.config/fish/config.fish file with values like

set -x COLUMNS 114
set -x LINES 48

or whatever size you prefer as long as it's more than 1.
based: https://fishshell.com/docs/current/cmds/set.html

another quick solution is to change the default terminal in VSCode; that might fix the issue.

[jared-thoughtbot]

@motebaya amazing, thank you! Both options worked but I settled on hardcoding the columns and lines in config.fish.

Weirdly it still doesn't detect my version manager but it is working 🤷

@jared-thoughtbot Have you tried setting the version manager manually? i think in log, LSP checking version manager because you haven't set it up yet.

Here's what i did:

1. in vscode, press CTRL + SHIFT + P, type version manager -> change version manager -> and select the version manager you have.
2. create a .ruby_version file with the ruby version you're using in current directory project.
3. adding the RUBY_VERSION variable to the ENV.

it might help.

I have the same issue but only in 1 project:

Automatic Ruby environment activation with rvm failed: Unexpected token 'N', "No preset "... is not valid JSON

Using RVM to manage Ruby but also asdf to manage NodeJS. Bash is my shell. Annoyingly, it’s not consistent, i.e. the LSP works for gems and all other Ruby/Rails projects I work on except for one. Last week it worked without issues IIRC.

[jared-thoughtbot]

@ur5us can you provide the content from the Output tab with Ruby LSP selected from the dropdown? Eg.

[ur5us]

@jared-thoughtbot I think I solved it. The problem was asdf complaining about NodeJS version as per .tool-versions not installed, though IMO that should not affect the Ruby LSP in the first place as I’m using RVM to manage my Ruby versions. For reference:

I believe #2552 should make this a bit more robust. Since we need to invoke the shell to integrate with version managers, we are susceptible to what gets printed by plugins or shell configs.

Hopefully, putting the JSON environment for the activation between separators will make this a bit more robust.
