Fasttext: compile problems on OS-X

[dcsan]

There is a binding for fastText for nodeJS, but upgrading to the latest master produces many compile time errors as below:

@dcsan I had the same problem, for this reason I prefer to use a simpler solution with a node.js wrapper of the latest binary - https://github.com/loretoparisi/fasttext.js
Of course a native binary through node-gyp would be the best, but there is no official release as for the python binding.

Hi @dcsan,
We do not officially maintain any javascript bindings for the moment. @loretoparisi did indeed a nice one.

I am closing this issue. Feel free to re-open it if you have a question about the fasttext library itself.

Best regards,

haha nearly a one year anniversary on this issue 🤣
well I was just using a simple exec wrapper thanks to @loretoparisi advice.

Do you suggest I should have waited a little bit to answer? ;-)
Glad to hear everything is ok.

Feel free to ping if you have any question.

@dcsan As @Celebio anticipated you should be able ru run seamless on linux / macOs with https://github.com/loretoparisi/fasttext.js
I'm planning to update in the next days with more functionalities!
