无法获取URL

Question

，这不是重复的，，我看过网上的所有回复。

每当我试图通过终端连接到一个网站时，我都会发现一个错误。很多解决方案都说先安装证书，然后再尝试，但我也做不到，因为那时我必须连接到https://pypi.python.org/simple/certifi/。我也尝试过--trusted-host，但仍然收到一个错误。

如果我试图在Python3.6文件夹中运行安装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: )
No matching distribution found for certifi

如果我尝试使用url连接python，然后尝试在终端中运行python，我也会得到SSL错误。让我也提一提，这是一个全新的问题。我昨天运行了同样的脚本，效果很好。

版本：

在脚本中添加以下行并执行脚本。也许它能解决你的问题。

import ssl
ssl._create_default_https_context = ssl._create_unverified_context
