How can we help?

First of all, thank you @hueniverse, for such a wonderful tool!

I did run into a bit of a problem though. I am getting this error when I run my hapi application:

/home/vehmloewff/Code/auto-deploy/node_modules/@hapi/hapi/lib/core.js:51
    actives = new WeakMap();                                                   // Active requests being processed
            ^

    at Object.<anonymous> (/home/vehmloewff/Code/auto-deploy/node_modules/@hapi/hapi/lib/server.js:9:14)

The line that node is complaining about is this: lib/core.js:51

I did some research and couldn't find anything about this. Any guidance/help would be greatly appreciated.

I don't think you're actually using node 12, make sure of that.

[Vehmloewff]

Maybe the node version logger broke, but I doubt that.

$ node -v
v12.14.1
$ npm start

/home/vehmloewff/Code/auto-deploy/node_modules/@hapi/hapi/lib/core.js:51
    actives = new WeakMap();                                                   // Active requests being processed
            ^

I'll take a guess and say you're using nvm or something like that. sudo loses context of that, you're getting your system's node version.

[Vehmloewff]

Oh. You are right. Thanks for the help!

I also ran into this issue... Why was engines removed from package.json? See https://github.com/hapijs/hapi/issues/3866. Version 19 requires Node 12 but this isn’t advertised in package.json or https://github.com/hapijs/hapi or https://www.npmjs.com/package/@hapi/hapi.
