点不能确认SSL证书 [英] Pip can't confirm SSL certificate

问题描述

我无法在一个系统上安装paramiko.相同的命令以前可以工作，但是后来发生了变化，我重新安装了Python，现在paramiko将无法安装.我正在将Windows 7与Python 3.6.4结合使用. Pip返回以下错误:

I am having trouble installing paramiko on one system. This same command worked earlier, but then something changed and I had reinstall Python, and now paramiko will not install. I am using Windows 7 with Python 3.6.4. Pip returns the following error:

C:\Users\me>pip --trusted-host pypi.python.org install paramiko
Collecting paramiko
  Could not fetch URL https://pypi.python.org/simple/paramiko/: 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 paramiko (from versions: )
No matching distribution found for paramiko

我该如何解决?

推荐答案

根据Paramiko 安装文档:

According to Paramiko installation documentation :

支持的版本:

• Python 2.7
• Python 3.4 +

好像您使用的是不兼容的Python版本

Looks like you are using incompatible version of Python

C:\Users\User>python -V
Python 3.6.4

安装

pip3 install paramiko 

或

pip install paramiko

SSL:CERTIFICATE_VERIFY_FAILED 可能是由pip 问题或在Mac上出现python问题

SSL: CERTIFICATE_VERIFY_FAILED can be caused by pip issue or python issue on Mac

请先将pip升级到最新版本.

Please upgrade pip to latest version for the same.

pip install --upgrade pip

此问题得到解决后

或者尝试安装增量

pip install incremental
