Next-translate: JavaScript heap out of memory when building

[BjoernRave]

When trying to build my application with next-translate && next build it crashes after some time because the heap is out of memory.

I have 21 pages + _document, _app and _error and three languages.

It works fine when doing next translate && next

running only next-translate first and then next build doesn't help

Version: 0.7.0
Next.js: 9.2.1

I tried in a project with same next version and next-translate version and it works well. The project that I tried is this one: https://github.com/aralroca/associacio_catalana_de_parkour

Can you provide me your next-translate config?

[BjoernRave]

sure:

[aralroca]

Thanks. I am still unable to reproduce it. Does it work with old versions as 0.6.0? Do you think it is something of the new release?

[BjoernRave]

no, I also tried it with 0.6.0, same result. It works fine when I deploy it to ZEIT Now though.

It's probably pretty hard for you to do anything about it, maybe it's also from the side of Next.js

[aralroca]

I guess is related with this next issue https://github.com/zeit/next.js/issues/7929

[BjoernRave]

@aralroca yea, probably. I will try it with the things suggested there tomorrow

[aralroca]

I'm going to close the issue, so looks that is not an issue from this lib. Feel free to reopen if I'm wrong.
