Linux系統安裝Python3-Linux系統-CentOS7

一、安裝依賴

yum install -y wget gcc zlib* openssl* bzip2-devel ncurses-devel sqlite-devel readline-devel tk-devel libffi-devel  

二、下載Python3安裝包

wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0.tgz

三、創建安裝目錄並解壓

mkdir -p /usr/local/python3

tar -zxvf Python-3.8.0.tgz

四、進入解壓後的目錄，編譯安裝

cd Python-3.8.0

./configure --prefix=/usr/local/python3

make && make install

五、建立python3的軟鏈

ln -s /usr/local/python3/bin/python3 /usr/bin/python3

六、將/usr/local/python3/bin加入PATH

vi /etc/profile

文本末尾添加：

export PATH=$PATH:/usr/local/python3/bin

退出：

使配置生效：

source /etc/profile

七、測試是否安裝成功

$ python3 -V
Python 3.8.0
$ pip3 -V
pip 19.2.3 from /usr/local/python3/lib/python3.8/site-packages/pip (python 3.8)
