Cannot resolve 'child_process' about neataptic

[jame-sparker]

Just to clarify goldsziggy's answer, you should add
"browser": { "fs": false, "child_process": false },
in package.json under node_modules/neataptic. Not in your package.json file.
Of course, it is best to update this repo directly instead of manually adding it.

not sure which i was using before, but I got around this by setting my node config with

{
   child_process: 'empty'
}

You're welcome, keep up the great work here, our future machine overlords demand it

Works for me thank you 😄

child_process is an external module, it should be included with Node. How are you running your code?

[skaraman]

as an npm module, it was working until i upgraded to the latest master branch update
node --version
v8.2.1

[wagenaartje]

Which version were you using before? The latest updates should not have affected multi-threading.

[wagenaartje]

Hmmm. And you were actually using the Node multi-threading option right? Because the only difference between 1.4.0 (when Node multi-threading was added) is 1.4.1 does not affect multi-threading. But i'll look into it.

[skaraman]

I don't think I have been, I've only recreated the XOR example and have been playing with mutations, training, and evolution options, and sometimes changing which kind of network I'm using. I haven't explicitly called out any multithreading.

[wagenaartje]

Thanks for the info 👍, that might mean you were using an older version (before multithreading was implemented).

So tagging along here as well. I saw this error when bundling neataptic with webpack. I was able to mitigate the issue locally by adding the browser field to the package.json

I added something along these lines and it fixed up the issue

"browser": { "fs": false, "child_process": false },

In short the browser field in the package.json is to help bundlers toggle which modules can be ignored for client-side bundling. Any room for a PR with the above?

+1 for this, i am unable to build

[prozoroff]

You can add the Pre hook into your package.json script section:

"prebuild": "json -I -f node_modules/neataptic/package.json -e 'this.browser={ \"fs\": false, \"child_process\": false }'",

First you need to install the json package if it is not in dependencies:

npm install --save json

PR created, would make this work out-of-the-box in Webpack builds.
