pip安装python三方库的时候提示 Could not fetch URL https://pypi.python.org/simple/pip/:

我这边是换了一个镜像就好了，具体操作步骤如下

mkdir .pip

cd .pip

vi pip.conf

将以下内容放入文件pip.conf中

[global]
timeout = 6000
index-url = http://pypi.douban.com/simple/ 
[install]
use-mirrors = true
mirrors = http://pypi.douban.com/simple/ 
trusted-host = pypi.douban.com

python -m pip install --upgrade pip（不要忘记更新一下）

 pip --trusted-host pypi.python.org  install  三方库

 

Yum 报错 curl#60 – “Peer’s Certificate has expired.”

Yum 安装提示

Cannot retrieve metalink for repository: epel/x86_64. Please verify its path and try again

或者

curl#60 – “Peer’s Certificate has expired.”

可能是由于服务器时间不正确导致https证书认证错误

更新服务器时间即可

例:

date -s “2017-4-25 12:00:00”

或者

ntpdate time.apple.com
