Build with state 'Succeded' but no files in folder/FileNotFoundException build.wasm does not exist

After dowlnoading hub and two newer versions of Unity (2017 and 2018.2.0f2) WebGL build stop working :/
Builds ends with state 'Succeded' but there is no files in build folder.
My project is in 2018.2.0f2 version.

In console i can see this:

Code (CSharp):

1. FileNotFoundException: C:\Users\Marek\Desktop\test\Temp\StagingArea\Data\linkresult_wasm\build.wasm does not exist
2. System.IO.File.Copy (System.String sourceFileName, System.String destFileName, System.Boolean overwrite) (at <f826c2584fc94ec19a48a6576640bdc5>:0)

8. UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

Log file is added to the thread.

Console and log are from new clear project wiht only cube added (this project also is not working).

Strange, but if i will do smth like dicribied in here:
https://forum.unity.com/threads/web...-of-the-time-requiring-a-full-restart.456418/
my new projects starts build correct.



Any ideas what the is happening?

 

I forgotten to write that both new versions of unity are installed on my second drive - D:/

 

After opening project in 2017 version all works fine. It seems that '2018.2.0f2' is making problems when building to WebGL platform

 

I'm using 2018.2.6f1. Get this error too. Change Linker Target to asm.js will make me build the project. But if I want to build as WebAssembly I still get this problem.
It seems Unity does not support WebAssembly very well now?? Or, Is there a simple solution for this problem?

 

Error messages are:

FileNotFoundException: F:\UnityTempProjects\TestBrick\Temp\StagingArea\Data\linkresult_wasm\build.temp.asm.js does not exist
System.IO.File.Copy (System.String sourceFileName, System.String destFileName, Boolean overwrite) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.IO/File.cs:107)
UnityEditor.FileUtil.UnityFileCopy (System.String from, System.String to, Boolean overwrite) (at C:/buildslave/unity/build/Editor/Mono/FileUtil.cs:210)
UnityEditor.FileUtil.CopyDirectoryFiltered (System.String source, System.String target, Boolean overwrite, System.Func`2 includeCallback, Boolean recursive) (at C:/buildslave/unity/build/Editor/Mono/FileUtil.cs:145)

 

Same problem after upgrading from 2018.2.2 to 2018.2.13f1. Is there a bug report for this somehere?
If I switch back "Linker Target" to "asm.js" it does work.
It also worked again after upgrading to 2018.2.20f1, but not sure if that was luck, with restarting Unity and stuff.

 

Come one... 2019 and I have the same problem

 

ahh.. . finaly i found a solution for this problem
i found its simply because unity WebAssembly
go in to unity=>PlayerSettings =>PublishingSettings=>LinkerTarget.
for me it was WebAssmbly and i catch empty folder after building
i just changed this to asm.js and its fixed!
if you do this way and still is not fix go on YourProject/Library/webgl_cache
and you can see this forlder (linkresult_asm_0C94....). go on this and delete all files in this folder
download this http://s9.picofile.com/file/8366922476/linkresult_asm.zip.html
and drop this files on there

 

@ThugLifeCompany You just saved tones of lives. Thank you very much!

 

i fix this problem here

you can follow my step to solve the problem
