Python Forum

I successfully built Python 3.8 on MacOS Sierra, by following the advice at the developer docs (via configure, make, make test, and make install). It's installed on a local directory, I did put the bin directory on my PATH, and everything seems to work fine.

However, I'm getting the infamous "SSL: CERTIFICATE_VERIFY_FAILED" error (which seems to be common in MacOS) when using a program that tries to download a package. The recommended practice is to execute the "Install Certificates. command" that comes with the prebuilt bundle. The problem is that I'm not using the prebuilt bundle, I just built it from source to a local directory, as I said above.

How can I proceed if I'm building from source?

Thanks!

I decided to download the precompiled installer, and extract the "Install Certificates.command" from it, then store the Python code it contains into a "installcerts.py" file (only the Python code, excluding a few non-Python lines), and then run "python3 ./installcerts.py"

It worked fine, but this should be documented somewhere, for users wanting to build from source on MacOS.
