I'm trying to install emsdk under Windows according to instructions there. I use Windows (10.0.19045.2728 freshly installed and updated, in a VM with open internet access). I install Python 3.11.3 (as admin with "Add python.exe to PATH"), download emsdk 2023-04-03 and unzip that to an emsdk folder, and in a cmd.exe prompt do

> emsdk install latest
Resolving SDK alias 'latest' to '3.1.35'

Error: Downloading URL 'https://storage.googleapis.com/webassembly/emscripten-releases-builds/deps/node-v14.18.2-win-x64.zip': 
Warning: Possibly SSL/TLS issue. Update or install Python SSL root certificates (2048-bit or greater) supplied in Python folder or https://pypi.org/project/certifi/ and try again.
error: installation failed!

What am I missing?

I tried

• pip install certifi (that succeeds, but does not cure it)
• python emsdk.py install latest (no change)
• using Python 3.9.13 (no change)
• under a Mint 21.1 VM with the same network access (it worked)

Ugly workaround: I successfully inserted this kludge in emsdk.py at start of download_file

    if url.startswith("https://storage.googleapis.com/"): # TODO fix/remove me
      url = "http"+url[5:]    # change https to http      # TODO fix/remove me
