catch FileNotFoundError if there aren't any certificates

[eaglegai]

I set verify to False, but it still need cerfiticate. As we have catched ImportError, why not catch FileNotFoundError together?

Expected Result

won't Traceback

Actual Result

[root@localhost requests]# ./test-requests.py
Traceback (most recent call last):
  File "/root/test/requests/./test-requests.py", line 2, in <module>
    import requests
  File "/usr/lib/python3.9/site-packages/requests/__init__.py", line 136, in <module>

Reproduction Steps

#!/usr/bin/python3
import requests
r = requests.get("http://127.0.0.1",verify=False)
print(r.text)

Hi @eaglegai, certifi is a declared dependency of Requests. This should be available in all installations. We derive the the DEFAULT_CA_BUNDLE_PATH being used in this line from requests.certs.where().

Can you confirm you 1.) have certifi installed and 2.) the value of import requests; requests.certs.where()?

Hi @nateprewitt , we build a mini environment which cut off the unnecessary packages, and in this env, we just import requestsfor http:// and verify is false is enough. It's not reasonable to force to load the certificates by default, because it's not necessary in the case that verify is false.

As we consider the case that isn't built with the ssl module, why not consider the situation that 'verify is false' needn't certificates.
