CentOS 安装 python3

发表评论

CentOS 安装 python3 是一篇基础环境架设的日志记录

一、安装记录

# 安装依赖包
sudo yum install gcc gcc-c++ cmake pcre pcre-devel \
autoconf libtool zlib zlib-devel bzip2 bzip2-devel \
ncurses ncurses-devel readline readline-devel \
openssl openssl-devel xz lzma xz-devel \
sqlite sqlite-devel tk tk-devel \
libffi libffi-devel openssl-static -y

# 1.从官网下载Python 3.10.5 - 06-Jun-2022 12:08 [stable version]
sudo curl -LO https://www.python.org/ftp/python/3.10.5/Python-3.10.5.tgz

# 2.解压至/usr/local
sudo tar -xvf Python-3.10.5.tgz -C /usr/local

# 3.生成Makefile
cd /usr/local/Python-3.10.5
sudo ./configure

# 4.编译解压
sudo make -j 8 && sudo make install

# 5.验证 python3 和 pip 安装成功
python3 --version
pip3 --version

二、特别说明

  • 在安装 python3 的时候，已经将 pip 功能安装好了
  • pip install 的时候，如果在中国，建议指定中国清华大学源，e.g
pip install example -i https://pypi.tuna.tsinghua.edu.cn/simple

安裝pip時報錯現象如下

解決辦法

  • 在系统目录C:\Users\用户\AppData\Roaming新建pip文件夹
  • 在pip文件夹下新建pip.ini文件，并写入如下配置： 
[global]
index-url = http://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host = mirrors.aliyun.com

注意

  • 安裝Windows版python.exe時，一定要以管理員模式打開並安裝，否則pip要人肉安裝，比如我
  • curl get-pip.py 時，可以在任意盤符目錄，但當前用戶一定能可以訪問到該目錄
  • 這個報錯是 pip 版本 >=7 時，使用鏡像源時，會提示源地址不受信任或不安全，需要ssl安全認證
