我跑sudo pip install git-review,并得到以下消息:

Downloading/unpacking git-review
  Cannot fetch index base URL http://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement git-review
No distributions at all found for git-review

有没有人对此有任何想法？

我正在练习'Web Scraping with Python'的代码,我一直有这个证书问题:

from urllib.request import urlopen 
from bs4 import BeautifulSoup 
import re

pages = set()
def getLinks(pageUrl):
    global pages
    html = urlopen("http://en.wikipedia.org"+pageUrl)
    bsObj = BeautifulSoup(html)
    for link in bsObj.findAll("a", href=re.compile("^(/wiki/)")):
        if 'href' in link.attrs:
            if link.attrs['href'] not in pages:
                #We have encountered a new page
                newPage = link.attrs['href'] 
                print(newPage) 
                pages.add(newPage) 
                getLinks(newPage)
getLinks("")

错误是:

  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py", line 1319, in do_open
    raise URLError(err)
urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1049)>

顺便说一句,我也在练习scrapy,但一直都在解决问题:找不到命令:scrapy(我在网上尝试过各种解决方案,但都没有用......真的很令人沮丧)

import yfinance as yf

msft = yf.Ticker("MSFT")

微软信息网

我尝试打印 msft.info 并收到“urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] 证书验证失败：无法获取本地颁发者证书 (_ssl.c:1108)”错误。我尝试重新运行 Install Certificates.command 和 Update Sheet.command 但显然它不起作用。另外，在我重新运行它们之后，我得到了这个消息： 由于环境错误无法安装软件包：[Errno 13]权限被拒绝：'/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/ certifi-2021.5.30.dist-info。

有什么建议我该如何修复它吗？

我安装了python 3.6

brew install python3

并尝试six.moves.urllib.request.urlretrieve从https 下载文件,但它会引发错误

ssl.SSLError:[SSL:CERTIFICATE_VERIFY_FAILED]证书验证失败(_ssl.c:749)

在Python安装(从.pkg)的,自述指示一个需要运行Install Certificates.command在安装后到

1. 安装 certifi
2. 符号链接路径的证书certify路径

能够使用证书.

但是,在brew安装中,此文件不存在,似乎不会运行.

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：

/usr/bin/python3来自 macOS 10.15 上的 Xcode/CLT（目前为 DB6/PB5，使用 Xcode 11 beta 6）SSL: CERTIFICATE_VERIFY_FAILED对于源自 PSL 的所有 HTTPS 请求失败，例如来自urllib.request：

$ /usr/bin/python3 -c 'import urllib.request; urllib.request.urlopen("https://www.apple.com/")'
...
urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1056)>

如何解决这个问题呢？

（我知道答案，很快就会发布；只是分享它以防其他人遇到它。）

我已经按照Peter Down关于将包推送到PyPI的说明http://peterdowns.com/posts/first-time-with-pypi.html

我有一个关于PyPI Live和PyPI测试的帐户,我可以登录并通过电子邮件验证帐户.

但是当我试图在我的回购中运行时:

python setup.py register -r pypitest

我明白了:

running register
running check
Registering [package_name] to https://testpypi.python.org/pypi
Server response (500): <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)>

知道出了什么问题吗？我的~/.pypirc文件也是根据我的用户名和密码编写的.

如何解决这个问题,以便我可以在PyPI上注册包？

我html.render()从requests_html图书馆跑。它正在尝试安装铬，但我收到一个错误

我已经尝试pip install --upgrade certifi过和没有sudo 并得到：Requirement already up-to-date: certifi in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (2019.6.16)

我也尝试运行/Applications/Python\ 3.6/Install\ Certificates command并得到：

我在Tensorflow上使用python 3.6和Keras（2.0.9）

尝试下载经过训练的resnet50模型，但遇到以下错误：异常：https : //github.com/fchollet/deep-learning-models/releases/download/v0.2/resnet50_weights_tf_dim_ordering_tf_kernels.h5上的URL提取失败：无- [SSL：CERTIFICATE_VERIFY_FAILED]证书验证失败（_ssl.c：777）

以下是使用的代码：

from keras.applications.resnet50 import ResNet50
from keras.preprocessing import image
from keras.applications.resnet50 import preprocess_input, decode_predictions
import numpy as np

model = ResNet50(weights='imagenet')

img_path = 'elephant.jpg'
img = image.load_img(img_path, target_size=(224, 224))
x = image.img_to_array(img)
x = np.expand_dims(x, axis=0)
x = preprocess_input(x)
model.summary()
preds = model.predict(x)

print('Predicted:', decode_predictions(preds, top=3)[0])

我已经设置了一个测试 MongoDb Atlas 帐户，只是其中一个免费帐户，并且在我的 Ubuntu 机器上使用以下代码我可以成功创建用户并搜索它们。

当我在 MacBook Air 上尝试完全相同的事情时，我得到了如下所示的 SSL 握手。

pymongo.errors.ServerSelectionTimeoutError: SSL 握手失败: [SSL: CERTIFICATE_VERIFY_FAILED] 证书验证失败 (_ssl.c:833),SSL 握手失败: [SSL: CERTIFICATE_VERIFY_FAILED] 证书验证失败 (_ssl.c:833),SSL 握手失败[SSL: CERTIFICATE_VERIFY_FAILED] 证书验证失败 (_ssl.c:833)

import pymongo
client = pymongo.MongoClient("mongodb+srv://MYUSERNAME:MYPASSWORD@cluster0-ABCDEF.mongodb.net/test")

collection = db.myjohnnytest

example = {'name' : 'Johnny',
            'email' : 'johnny@test.net'}

user_id = collection.insert_one(example).inserted_id

我发现这个答案似乎是关键：

堆栈溢出答案

但是我已经尝试过这个，无论我是完全遵循它还是激活我的 virtualenv，我都会收到以下错误：

当我执行以下操作时：

>>> import gensim.downloader as api
>>> model = api.load("glove-twitter-25")  # load glove vectors

gensim.downloader API 抛出以下错误：

我究竟做错了什么？
