On macOS we started to observe an error when emsdk update-tags is performed:

What is cause by unaccessibility of https://s3.amazonaws.com/mozilla-games/emscripten/packages/llvm/nightly/osx_32bit/index.txt

I wonder if this was some kind of transient error. Can you try again if the error still occurs?

Hi, just tested on different machine, linux this time:

root@e9ee50aded49:/emsdk_portable# ./emsdk  install node-4.1.1-32bit
Installing tool 'node-4.1.1-32bit'..
Error downloading URL 'https://s3.amazonaws.com/mozilla-games/emscripten/packages/node-v4.1.1-linux-x86.tar.gz': <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)>
Installation failed!

---

Update to this commend: on linux it was my fault due missing ca-certificates package

I've tried to reproduce this on multiple different systems, but have been unable to. Which OS X version was this on? Does this happen if you reinstall from the portable installer from scratch?

I am having the same issue on mac os high sierra 10.13.2. Any updates on this ?

[juj]

Sorry, currently it's unknown as to why this would be happening. What is the exact error message log that gets printed?

These are the errors I am getting.

Please copy at least something relevant because, as we know, stuff disappears off the internet without notice.

Running /Applications/Python\ 3.6/Install\ Certificates.command from terminal fixed the problem for me on Mac OSX.

This works for me, I only change the python version to 3.8 in my case, and then run again the

./emsdk install latest script
