Seems like a duplicate of #1357

Somehow your system version python isn't able to validate certificates.

What does which python and which python3 say?

What distribution are you using?

[wetbadger]

/home/worryword/.pyenv/shims/python
and
/home/worryword/.pyenv/shims/python3

python version is: 3.9.13

Distro is Linux Mint 21.1

I would recommend following the various pieces of advice in #1357. Several folks seems to have had the same issue.

One think I notice is that .pyenv seems to be some kind of virtual environment. Do you have /usr/bin/python3 on your system? What happens if you try using that directly (i.e. /usr/bin/python3 emsdk.py install latest)

OK to close this issue as a duplicate?

[wetbadger]

Your advice to use /usr/bin/python3 emsdk.py install latest worked. If it is a true duplicate I am not sure because many of them are saying they had to use python2.7.

[sbc100]

There may be different root causes but the net result is CERTIFICATE_VERIFY_FAILED due to some kind of issue with the pre-exiting python installation.

Its hard to know what emscripten can do about this since we kind of depend on a working copy of python.

Fixed in #1355
