The command npm init slidev@latest seems to end with a bunch of errors. ⚠️

I don't typically use npm for my work. So, if I am missing something obvious, please point it out so I could get slidev to work.

I checked after the installation: there was a folder by the project-name, slidev. The folder also has a bunch of files (see screenshot below).

But, when I checked http://localhost:3030/ (as mentioned here), there was no server running anything on it.

Slidev installation output (multiple errors)

$ npm init slidev@latest
npx: installed 22 in 2.04s

I was able to resolve the installation issue using the following steps. See Option 2: Update Node.js with NPM (Node Package Manager) in this document.

First, clear the npm cache.
```
npm cache clean -f
```
Install n, Node’s version manager.
```
sudo npm install -g n
```
With the n module installed, install the latest stable version of node.
```
sudo n stable
```
After this step there was a path update:
the node command changed location and the old location may be remembered in your current shell.
- old : /usr/bin/node
- new : /usr/local/bin/node
Finally, open a new terminal and run npm init slidev. This worked for me and the server started without any error. ⚡
