python - 无法获取网址

Question

这不是重复的。我已经阅读了所有在线回复。

每当我尝试通过终端连接到网站时，我都会收到错误消息。许多解决方案都说先尝试安装 certifi，然后再尝试，但我也不能这样做，因为那样我就必须连接到 https://pypi.python.org/simple/certifi/ .我也试过 --trusted-host 但我仍然收到错误。

如果我尝试在 Python 3.6 文件夹中运行 Install Certificates.command，则会出现以下错误:

/Applications/Python\ 3.6/Install\ Certificates.command ; exit;
 -- pip install --upgrade certifi
Collecting certifi
  Could not fetch URL https://pypi.python.org/simple/certifi/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777) - skipping
  Could not find a version that satisfies the requirement certifi (from versions: )

如果我尝试使用 url lib 在 python 文档中连接，然后尝试在终端中运行 python 文档，我也会收到 SSL 错误。我还要提一下，这是一个全新的问题。我昨天运行了相同的脚本并且运行良好。

在脚本中添加以下行并执行脚本。可能会解决您的问题。

import ssl
ssl._create_default_https_context = ssl._create_unverified_context
