Wasm build fails

[fatichar]

I get this error when I build my WASM project:

Also:

Putting MSBuild project build output verbosity to Normal:

Only

There is no emsdk folder including emsdk_env.bat

Using the latest versions of Uno and Skiasharp

@fatichar this generally means that there's a discrepancy in referenced packages. If you can provide a repro project, it'll help determine which one that is.

@navio-n if you're getting this error, it's likely that emscripten did not get installed properly. It's generally caused by git or python missing on your system. Try deleting C:\Users\User.uno\emsdk and build again.

Thanks for the logs. It's the same issue indeed. Can you do the following:

• Delete the C:\Users\nikol\.uno\emsdk folder
• Immediately after, without any other wasm build happening, build your project again with skia enabled and binlog enabled

Post the resulting log. Thanks!

On this computer, this solved the problem. Now it is built.

emsdk-2.0.23 is now cca 1.3GB

On old computer where it is not working is only 2.5MB.

Strange

In your other computer, you're still getting the python error that is related to SSL certificates and file downloads. Maybe uninstalling Python and reinstalling it could help?

[navio-n]

Tried to reinstall but then figured out that the Inkscape SVG program installed in his folder was some lower version of Python. Now it is working on both computers!

Very good, thanks for the updates!
