我试图在Mac OS X 10.7.5上下载NLTK 3.0以用于Python 3.6,但是我收到了SSL错误:

import nltk
nltk.download()

我用pip3命令下​​载了NLTK : sudo pip3 install -U nltk.

更改NLTK下载程序中的索引允许下载程序显示所有NLTK文件,但是当尝试下载所有文件时,会发生另一个SSL错误(请参阅照片底部):

我对计算机科学比较陌生,对SSL一点也不陌生.

我的问题是如何简单地解决这个问题？

以下是遇到相同问题的用户的类似问题:

无法下载nltk数据

我决定发布一个带截图的新问题,因为我对其他问题的编辑被拒绝了.

类似的问题,我没有找到帮助:

NLTK下载SSL:证书验证失败

使用nltk.download()下载错误

尝试为nltk安装Punkt时出现以下错误:

nltk.download('punkt')    
 [nltk_data] Error loading Punkt: <urlopen error [SSL:
 [nltk_data]     CERTIFICATE_VERIFY_FAILED] certificate verify failed
 [nltk_data]     (_ssl.c:590)>
False

Pip总是失败,即使我做pip install dedupe或pip install --trusted-host pypi.python.org dedupe

无论如何,输出总是相同的:

收集重复数据删除

重试(重试(总计= 4,连接=无,读取=无,重定向=无,状态=无))连接被"SSLError"破坏后(SSLError(1,'[SSL:CERTIFICATE_VERIFY_FAILED]证书验证失败(_ssl.c: 777)'),)':/ simple/dedupe/
Retrying ...

跳绳

找不到满足需求重复数据删除的版本(来自版本:)没有找到重复数据删除的匹配分布

所以我卸载了anaconda并重新安装了它.一样.

你认为问题是我的_ssl.c文件(我不知道它在哪里)必须是腐败的还是什么？为什么pip需要引用,如果我告诉它绕过ssl验证呢？

这是我在 python3 中的代码：

import pandas as pd

tables = pd.read_html("http://http.com/")

print(tables)

我收到了这个错误：

我通过Anaconda在Python 3.5.2上运行OS X El Capitan并且拥有spaCy 0.101.0.

我正在尝试使用安装spaCy英语语言模型python -m spacy.en.download.但是,当我这样做时,我得到一个错误urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:645)>.完整的Traceback如下:

我的Python安全websocket客户端代码给我例外如下:

[SSL:CERTIFICATE_VERIFY_FAILED]证书验证失败(_ssl.c:748)

我已经创建了我的私有证书和签名证书,但我无法使用Python脚本连接到它,如下所示:

import json
from websocket import create_connection


class subscriber:
   def listenForever(self):
   try:
      # ws = create_connection("wss://localhost:9080/websocket")
      ws = create_connection("wss://nbtstaging.westeurope.cloudapp.azure.com:9090/websocket")
      ws.send("test message")
      while True:
          result = ws.recv()
          result = json.loads(result)
          print("Received '%s'" % result)

      ws.close()
  except Exception as ex:
      print("exception: ", format(ex))


try:
    subscriber().listenForever()
except:
    print("Exception occured: ")

我在python中使用龙卷风的https/wss服务器脚本如下:

import tornado.web
import tornado.websocket
import tornado.httpserver
import tornado.ioloop
import os
import ssl

ssl_root = os.path.join(os.path.dirname(__file__), 'ssl1_1020')


class WebSocketHandler(tornado.websocket.WebSocketHandler):
    def check_origin(self, origin):
        return True

    def open(self):
        pass

    def on_message(self, message):
        self.write_message("Your …
