處理辦法：

打開(kāi)以下目錄，并創(chuàng)建pip文件夾

C:Users用戶AppDataRoaming

進(jìn)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(huì)報(bào)錯(cuò)了

補(bǔ)充知識(shí)：處理Python3中使用pip install時(shí)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(qǐng)安裝epel-release)

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

使用pip安裝包時(shí)會(huì)提示你pip版本過(guò)低, 建議使用pip install --upgrade pip命令來(lái)升級(jí).

而使用該命令時(shí)則會(huì)彈出一連串錯(cuò)誤提示, 其中包含關(guān)鍵字'SSL: CERTIFICATE_VERIFY_FAILED'

這時(shí)的處理辦法是跳過(guò)pip的SSL驗(yàn)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?jī)?nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持好吧啦網(wǎng)。
