處理辦法：

打開以下目錄，并創(chuàng)建pip文件夾

C:\Users\用戶\AppData\Roaming

進入pip文件夾，創(chuàng)建pip.ini文件，內(nèi)容如下

[global]
index-url = http://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host = mirrors.aliyun.com

此配置的作用是修改pip的安裝源，此處修改為阿里的源，然后使用pip install安裝就不會報錯了

補充知識：處理Python3中使用pip install時提示"SSL: CERTIFICATE_VERIFY_FAILED"

CentOS7使用官方y(tǒng)um源安裝了Python3和pip(yum搜不到python3的話請安裝epel-release)

[root@client0 yum.repos.d]# python3 --version
Python 3.6.8
[root@client0 yum.repos.d]# pip3 --version
pip 8.1.2 from /usr/lib/python3.6/site-packages (python 3.6)

使用pip安裝包時會提示你pip版本過低, 建議使用pip install --upgrade pip命令來升級.

而使用該命令時則會彈出一連串錯誤提示, 其中包含關鍵字"SSL: CERTIFICATE_VERIFY_FAILED"

這時的處理辦法是跳過pip的SSL驗證

使用命令

pip3 install --trusted-host pypi.org --trusted-host files.pythonhosted.org <package_name>

即可.

以上這篇Python pip install之SSL異常處理操作就是小編分享給大家的全部內(nèi)容了，希望能給大家一個參考，也希望大家多多支持腳本之家。
