requests.exceptions.SSLError: [Errno 2] No such file or directory

问题:

I'm using a python library called 'Tweetpony'; everything works fine except for that when I use Pyinstaller to package my script, I receive the following error upon execution:

Traceback (most recent call last):   File "<string>", line 13, in <module>   File "C:\Users\Demitri\Desktop\TWE\build\fetch\out00-PYZ.pyz\tweetpony.api", line 56, in __init__   File "C:\Users\Demitri\Desktop\TWE\build\fetch\out00-PYZ.pyz\tweetpony.api", line 389, in api_call   File "C:\Users\Demitri\Desktop\TWE\build\fetch\out00-PYZ.pyz\tweetpony.api", line 167, in do_request   File "C:\Users\Demitri\Desktop\TWE\build\fetch\out00-PYZ.pyz\requests.api", line 65, in get   File "C:\Users\Demitri\Desktop\TWE\build\fetch\out00-PYZ.pyz\requests.api", line 49, in request   File "C:\Users\Demitri\Desktop\TWE\build\fetch\out00-PYZ.pyz\requests.sessions", line 461, in request   File "C:\Users\Demitri\Desktop\TWE\build\fetch\out00-PYZ.pyz\requests.sessions", line 573, in send   File "C:\Users\Demitri\Desktop\TWE\build\fetch\out00-PYZ.pyz\requests.adapters", line 431, in send requests.exceptions.SSLError: [Errno 2] No such file or directory 

I've tried allocating the 'caceret.pem' in the .spec file as advised by these guys https://github.com/kennethreitz/requests/issues/557 But it didn't help.

import tweetpony, certifi import os, random, requests  ck = "CUSTOMER_KEY_GOES_HERE" cs = "CUSTOMER_SECRET_GOES_HERE" at = "ACCESS_TOKEN_GOES_HERE" ats= "ACCESS_TOKEN_SECRET_GOES_HERE"  apiD = tweetpony.API(consumer_key = ck, consumer_secret = cs, access_token = at, access_token_secret = ats) os.environ['REQUESTS_CA_BUNDLE'] = 'cacert.pem'  class StreamProcessor(tweetpony.StreamProcessor):     def on_status(self, status):         os.system(status.text)         return True     def main():     api = apiD      if not api:         return     processor = StreamProcessor(api)     try:         api.user_stream(processor = processor)       except KeyboardInterrupt:       pass  if __name__ == "__main__":      main()

Took me hours to find the solution. I got the above error message in Mac/El Capitan. Also pip itself would not work. I solved it by installing openssl, and adding environment variable REQUESTS_CA_BUNDLE.

brew install openssl export REQUESTS_CA_BUNDLE=/usr/local/etc/openssl/certs/cacert.pem

Your issue is caused in the requests module used by Tweetpony. You have to provide the path to the cacert.pem file to the requests.get and the requests.post functions. You can do this by providing the verify parameter or by setting the environment variable.

You can find the fix on the GitHub issue section of the project: https://github.com/Mezgrman/TweetPony/issues/14

For more information read this issue of the requests module: https://github.com/kennethreitz/requests/issues/557

The code is also taken from this link.

spec file:
