Question

我正在使用名为'Tweetpony'的python库;一切正常，除了当我使用Pyinstaller打包我的脚本时，我在执行时收到以下错误：

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__

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

我尝试按照这些人https://github.com/kennethreitz/requests/issues/557的建议在.spec文件中分配'caceret.pem' 但它没有帮助。

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()

花了我几个小时才找到解决方案。我在Mac / El Capitan中收到了上述错误消息。 pip本身也行不通。我通过安装openssl并添加环境变量REQUESTS_CA_BUNDLE来解决它。

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

您的问题是由Tweetpony使用的请求模块引起的。您必须向cacert.pem和requests.get函数提供requests.post文件的路径。您可以通过提供verify参数或设置环境变量来完成此操作。

您可以在项目的GitHub问题部分找到修复程序： https://github.com/Mezgrman/TweetPony/issues/14

cert_path = resource_path('cacert.pem')
# this would also work, but I'd rather not set unnecessary env vars
# os.environ['REQUESTS_CA_BUNDLE'] = cert_path
print requests.get('https://www.google.com/', verify=cert_path).text

spec文件：

requests.exceptions.SSLError：[Errno 2]没有这样的文件或目录
