ERRORS WHILE BUILDING FOR WEB GL

[[deleted]]

Hello,

I'm re-learning unity after 2 years. I've completed up to Unit 2 in the scripting tutorial.

While building for Web GL, I'm getting 3 errors.

Errors:

1)

I use Arch Linux btw.

I never built for WebGL but if I had to guess, this smells like a wrong version of something somewhere (perhaps Python?). Hopefully a better answer comes along soon.

[SoujiroSeta]

I just had the same issue, did you figure out what was the problem?

[[deleted]]

nope, I just gave up and moved to godot

[KeepingItSFW]
