Python 错误“NetworkError: [SSL: CERTIFICATE_VERIFY_FAILED] 证书验证失败 (_ssl.c:661)

Question

How it broke

While troubleshooting my command line trying to ssh root@ip into Docker, I seem to I have messed up with openssl , somehow.

I can now connect to Docker, but I no longer can run scripts which require requests .

1st attempt

At first I did not know what was wrong.

If I ran script.py , it would just halt and fail silently.

2nd attempt

Then I tried to run the same script from within a conda env , which has openssl installed, and this time error was verbose, ending with:

NetworkError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:661)

openssl upgrade

I have then tried to upgrade it system-wide with brew upgrade openssl , after which I got the following Caveats:

A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
  /usr/local/etc/openssl/certs

and run
  /usr/local/opt/openssl/bin/c_rehash

and I did it.

my .ssh/ has:

github_rsa
github_rsa.pub
id_boot2docker
id_boot2docker.pub
id_rsa
id_rsa.pub
known_hosts

Answer 1

the problem was a library called billboard.py , being imported.

this import was causing the problem and halting the program, and the reason needs further investigation.

verbose Error was because conda env did not have all requeriments to run the program.
