服務器安裝python3環境

服務器安裝python3環境

先安裝相關包

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

下載python源碼包

wget https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tar.xz

解壓源碼包

tar -Jxvf Python-3.6.6.tar.xz 

配置安裝路徑

切換到解壓目錄下
cd Python-3.6.6
./configure prefix=/usr/local/python3

編譯安裝

　　make && make install 

創建軟連接

 ln -s /usr/local/python3/bin/python3 /usr/bin/python3
 ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

如果遇到bug

# ln: failed to create symbolic link '/usr/bin/python3': File exists

說明已經有鏈接鏈到 /usr/bin/python上了，覆蓋即可，使用命令

 ln -sf /usr/local/python3/bin/python3 /usr/bin/python3
 ln -sf /usr/local/python3/bin/pip3 /usr/bin/pip3

安裝完成

使用pip安裝包前,先更新pip

pip3 install --upgrade pip
