I'm developing a ruby app in a devcontainer in VScode. In the container I am a non-root user. Now I want to install the Ruby LSP extension in the devcontainer, but I get following errors:
Failed to setup the bundle: Command failed: gem install ruby-lsp ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions for the /usr/local/bundle/gems/sorbet-runtime-0.5.11514 directory.

Even if I pre-install the gems locally and then install the extension...
# Gemfile
gem "ruby-lsp"
gem "rubocop"
...I get the same error.
Can someone please tell me what I have to do to get this extension to work? Is there a setting?
The vendor guidance for use with VS Code is to NOT install the gem:

If using VS Code, all you have to do is install the Ruby LSP extension to get the extra features in the editor. Do not install the ruby-lsp gem manually.
