you need to run npm install -g node-gyp

Deleting the content of referenced directory worked for me (sf cli 2.0) /Users/kosit/.local/share/sf/

--mutex=file:/Users/oelizon/.local/share/sfdx/yarn.lock

[jweston491]

I am having the same issue.

[steinwinde]

you need to run npm install -g node-gyp

@lumacerqueira - thanks! I had a very similar problem like the OP and this fixed it for me. But how did you know, where is this documented? Is there any more pertinent installation instruction than https://developer.salesforce.com/tools/vscode/en/localdev/set-up-lwc-local-dev ?

So running the problematic yarn add @salesforce/lwc-dev-server@latest command using Node 18 seems to work, but it doesn't work with Node 20. And it looks like the version of Node.js bundled in the Salesforce CLI was upgraded to v20 in the 2.16.7 (Nov 8, 2023) release. I managed to get plugin installed correctly when using a version of the CLI before this update.

I'm having the same issue. Does anyone find a solution?

[theevenator]

Found a solution that worked for me. It seems the issue stems from using node v20 for some reason with this plugin. I used nvm to downgrade to 18.17.0 nvm install 18.17.0, had to re install the sf CLI using npm npm install @salesforce/cli --global and then ran sf plugins install @salesforce/lwc-dev-server which installed successfully @salesforce/cli: Installing plugin @salesforce/lwc-dev-server@latest... installed v2.11.0
