Install and Usage code for js-libp2p-webrtc-star

[Annamarie2019]

For js-libp2p-webrtc-star-signalling-server, there are 3 issues:

• The code, > npm install -g @libp2p/webrtc-star-signalling-server copies the > sign, so you'll get a message about Usage untill the user realizes the > got copied and removes it. Better to not include the >
• Once you realize the problem and run the code, you get a permissions error. (see image)
• The code,$ webrtc-star --port=13579 --host=127.0.0.1 ... same problem as above: copies the $

I'm already logged in as Admin.

Here's the end of the log, where the error shows up:

Those instructions leave out the fact that you've got to clone the repository, cd into the correct folder, and then run those commands (without the > and $).

Here's what I did (> denotes the output from each command):

1. Clone the repo:

   git clone https://github.com/libp2p/js-libp2p-webrtc-star.git
   
   
   > Cloning into 'js-libp2p-webrtc-star'...
   > remote: Enumerating objects: 2665, done.
   > remote: Counting objects: 100% (629/629), done.
   > remote: Compressing objects: 100% (257/257), done.
   
   > remote: Total 2665 (delta 420), reused 542 (delta 361), pack-reused 2036
   > Receiving objects: 100% (2665/2665), 1.66 MiB | 9.42 MiB/s, done.
   > Resolving deltas: 100% (1617/1617), done.

2. Move into the directory:

   cd js-libp2p-webrtc-star

3. Install the local @libp2p package:

   npm nstall -g @libp2p/webrtc-star-signalling-server

   > 
   > 2 packages are looking for funding
   >   run `npm fund` for details
   > 
   > found 0 vulnerabilities

4. Start the webrtc server:

   webrtc-star --port=13579 --host=127.0.0.1
   
   > @libp2p/[email protected]
   > Listening on: http://127.0.0.1:13579

Thanks, @johnnymatthews I was able to execute 1 and 2, but I got a permissions error again on 3. (Also, please note typo in "nstall")

I think I need permissions to libp2p.

No, this isn't a libp2p issue. If it were, we'd be seeing errors from git. It looks like your NPM installation has some funky issues going on. I'd recommend completely uninstalling NPM, and then installing NVM, and managing your NPM installations that way.
