v1.40.1 build error using the emscripten-supplied python3

[ema...@cfa.harvard.edu]

After updating to v1.40.1 from v1.39.19, I get the error shown below when using the emscripten-supplied version of python3. Utilizing my own previously installed version of python3 (which has 'requests' installed) works fine.

Running 'emcc --clear-ports', as suggested, did not help in this case.

Regards,

Eric

Thanks for the bug report.  Would you mind opening an issue in the emsdk repo?

So far I'm managed to confirm that this does not occur on our CI machines:

```

$ /Users/distiller/project/python/3.7.4_64bit/bin/python3 /Users/distiller/project/upstream/emscripten/embuilder.py build bzip2 --force

embuilder:INFO: building and verifying bzip2
root:INFO: Cache: deleting cached file: /Users/distiller/project/upstream/emscripten/cache/wasm/libbz2.a
cache:INFO: generating port: libbz2.a... (this will be cached in "/Users/distiller/project/upstream/emscripten/cache/wasm/libbz2.a" for subsequent builds)
cache:INFO:  - ok
embuilder:INFO: ...success
```

We need to figure out what is different about your setup that causes this failure.

cheers,

sam

Can you try running this command from the emsdk directory and see if if fixes these issue:

```

$ python/3.7.4_64bit/bin/python3 ./python/3.7.4_64bit/bin/pip3 install certifi

```

I suspect it might but since I can't repro I can't confirm.

cheers,

Installing certifi did not fix my problem, but installing requests did:

````

python/3.7.4_64bit/bin/python3 ./python/3.7.4_64bit/bin/pip3 install requests

````

Is this the answer ... and, if so, do you still want me to open an issue?

Yes, please.  That way we can track the issue through to fixing it.
