Emscripten: portable sdk installation fails.

[lukasschmit]

I am trying to install the latest portable sdk on OSX. I ran ./emsdk update successfully, but the next step, ./emsdk install latestcrashes with the following after a few seconds:

HTTP error with URL 'https://s3.amazonaws.com/mozilla-games/emscripten/packages/llvm/tag/osx_64bit/emscripten-llvm-e1.37.13.tar.gz': HTTP Error 403: Forbidden
Installation failed!

I tried using sudo and that made no difference. Seems like this llvm file was uploaded incorrectly or something.

I should point out a few other files download seemingly successfully first. Here's the full output:

I have this problem too.
it seems they are playing with file permissions since past hours :))

You can do ./emsdk install sdk-1.37.12-64bit instead of ./emsdk install latest, it has no permission problem.

@AliKarami Oh thanks that worked!

[CoreyDotCom]

Having same issue (I suppose we all are) with latest.

Sorry about this, I notice that this is caused by a regression from https://github.com/juj/emsdk/pull/76. The workaround @AliKarami suggests is a good one, as we don't yet have 1.37.13 installers available on OS X due to https://github.com/WebAssembly/binaryen/issues/1035, but Linux does have 1.37.13. The problem here was that OS X is misidentified as Linux for the purposes of detecting which SDK versions are available.

[juj]

This should now be resolved and both emsdk install latest and emsdk install sdk-1.37.13-64bit should work.

However while working on this, I noticed that it's possible that emsdk update returns without printing anything and does not actually update emsdk. If that is the case, try redownloading emsdk_portable from a zip file (https://s3.amazonaws.com/mozilla-games/emscripten/releases/emsdk-portable.zip for Windows and https://s3.amazonaws.com/mozilla-games/emscripten/releases/emsdk-portable.tar.gz for OS X)

If the issue still appears with latest, feel free to reopen.

I got the same error while running the below scripts

Any suggestions

The printed error log looks different, it mentions a SSL error, rather than a 403 Forbidden. The 403 Forbidden was caused by a missing file on the S3 bucket. The SSL error seems to be something to do with unagreeable handshake with your system and the Amazon S3 services. Not sure how to resolve that though.

Does

wget https://s3.amazonaws.com/mozilla-games/emscripten/packages/emsdk_windows_update.zip

work on your system? Or via curl?

curl -O https://s3.amazonaws.com/mozilla-games/emscripten/packages/emsdk_windows_update.zip

Or attempting to download the URL directly in a web browser?

This is all about Python version!!!!

Actual fix is to use the exact python version specified in the documentation. Git has some changes related to python, so if there is wrong paths fetched for python, these kind of error will occur. if you are on macos , type python , then you will see python version number. try to update to different versions by installing new one. if nothing works, you have to uninstall python versions which you manually installed recently. I tried all other alternatives and this worked for me perfectly.
