@VincenzoMeschi The error you are seeing is not due to @oclif/config deprecation but the error that follows it. Would you provide the full terminal output from your attempt to install lwc dev server?

This was all that I got after attempting to install.

@VincenzoMeschi Try this sf plugins install @salesforce/lwc-dev-server --dev-debug

@peternhale I get the exact same error as @VincenzoMeschi and can provide the full terminal output. See below. My apologies in advance if this is not good protocol to comment in this way, this is my first time commenting on a open source repo and looking at README and CONTIRBUTING I can't see any particular protocols related to comments.

Hi @VincenzoMeschi and @ajmAAid,

The LWC dev server is now deprecated, so we will not be actively maintaining this plugin. However, you can still continue to use it as is.

As for the installation issue, I'm able to install the @salesforce/lwc-dev-server plugin when I'm using a CLI version that runs on Node 18 but not a CLI version that runs on Node 20. (Run sf --version to check - the last part tells you what Node version your CLI is running on.)

If you installed the CLI using the installer, it comes bundled with Node 20, as the CLI Team has already done the Node upgrade a few months ago. In that case, you'll need to uninstall your existing CLI version and install a new one via npm. (Uninstalling the existing version is important - otherwise your computer and VSCode are going to get confused about which one to use!)

Here are the instructions to install the new CLI on Node 18 via npm:

1. Uninstall the old version by following these instructions: https://developer.salesforce.com/docs/atlas.en-us.sfdx_setup.meta/sfdx_setup/sfdx_setup_uninstall.htm
2. Ensure the CLI is uninstalled by making sure sfdx --version and sf --version don't result in anything
3. Install Node 18 (nvm install 18 if you have nvm; otherwise https://nodejs.org/en/download/current and select Node 18 from the dropdown)
4. Run npm install @salesforce/cli --global in the Terminal to install the latest version of the Salesforce CLI
5. sf plugins install @salesforce/lwc-dev-server

Let me know if this fixes your installation issue!
