Hello! I’m having some trouble following along with the HelloWorld p5bots tutorial: [https://github.com/sarahgp/p5bots/blob/master/examples/HelloWorld.md](https://github.com/sarahgp/p5bots/blob/master/examples/HelloWorld.md)

I keep getting a bunch of errors when I try to run “npm install -g p5bots-server.”

I also posted on the GitHub Issues page in the thread in which people were posting about similar issues, but it seems to be less active. ([https://github.com/sarahgp/p5bots/issues/31](https://github.com/sarahgp/p5bots/issues/31))

Here are some of the errors I get in the terminal:

```auto
node-pre-gyp http 404 https://github.com/EmergingTechnologyAdvisors/node-serialport/releases/download/4.0.7/serialport-v4.0.7-node-v72-darwin-x64.tar.gz

```

Thanks in advance for your help!

Were you able to resolve this? 404 errors mean that whatever script / installer / tutorial / example you were following, it refers to files that aren’t at that path.

Here is the release that those error urls appear to be referring to:

- [Release v4.0.7 · serialport/node-serialport · GitHub](https://github.com/serialport/node-serialport/releases/4.0.7)

Notice that your urls say “v72” but that isn’t in the releases list, which include various numbers from v11 to v57.

Thanks for the link and suggestions, Jeremy. I ended up getting it to work just yesterday by using Node version 0.12.9 (using “nvm install 0.12.9”), but perhaps going into the code from the tutorial I was following and changing the v# will be a better solution!
