WebGL fails to build under 2018.3b12

Target Platforms Web

Hello,

I was just trying to build my Unity project using WebGL but I keep running into this error:

OSError: [Errno 2] No such file or directory

Here is the full error message:

I get a notification that the build succeeded but the output directory is empty.

This is on Mac OS X 10.13.6.

I have seen this happen when paths contained non-Latin characters but all of my paths are composed of Latin characters only.

This was also happening under b11.

Any idea is this s a bug or something in my environment? The error message doesn’t give me any indication as to which file is missing.

2

does it fail if you build an empty project?

3

I just tried and it does fail with an empty project. (same error message)

I have created bug 1107593 for this issue.

(side note: I also created 1107588 for a bug where the scene list contains only a deleted scene in new projects)
