Installation of sage 9.7 from source works fine. Then, when I try to install the optional package nodejs (sage -i nodejs), I get the following error:
[nodejs-12.18.3] urllib.error.URLError: urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)
[nodejs-12.18.3] Error installing nodejs ... exiting
The problem occurs on opensuse tumbleweed and opensuse leap 15.4 on various machines with different processors.
