Could not find a version that satisfies the requirement requests (from versions: )

处理办法:

打开以下目录,并创建pip文件夹

C:\Users\用户\AppData\Roaming

进入pip文件夹,创建pip.ini文件,内容如下

[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的安装源,此处修改为阿里的源,然后使用pip install安装就不会报错了

补充知识:处理Python3中使用pip install时提示"SSL: CERTIFICATE_VERIFY_FAILED"

CentOS7使用官方yum源安装了Python3和pip(yum搜不到python3的话请安装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安装包时会提示你pip版本过低, 建议使用pip install --upgrade pip命令来升级.

而使用该命令时则会弹出一连串错误提示, 其中包含关键字"SSL: CERTIFICATE_VERIFY_FAILED"

这时的处理办法是跳过pip的SSL验证

使用命令

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

即可.

以上这篇Python pip install之SSL异常处理操作就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持。
