安裝依賴包
在安裝python之前需要先安裝依賴包
yum install gcc patch
yum install libffi-devel
yum install python-devel
yum install zlib-devel
yum install bzip2-devel
yum install openssl-devel
yum install ncurses-devel
yum install sqlite-devel
yum install readline-devel
yum install tk-devel
yum install gdbm-devel
yum install db4-devel
yum install libpcap-devel
yum install xz-devel -y
或者
yum install gcc patch libffi-devel python-devel zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel -y解壓檔案tar -xvzf python-3.5.1.tgz
配置編譯並安裝
首先cd到解壓目錄下
./configure --prefix=/usr/local/python3
make
make install
警告make install
可以覆蓋或偽裝python3
二進位制檔案。因此,建議使用make altinstall
而不是make install
,因為後者只安裝了exec_prefix
/bin/pythonversion
新增環境變數
vim /etc/profile
新增 /usr/local/python3/bin
export path="/usr/local/nginx/sbin/:/usr/local/python3/bin:$path"
source /etc/profile
或者參加軟鏈結
ln -s pip3.5 /usr/local/bin/pip3
ln -s python3.5 /usr/local/bin/python3
在/etc/profile下配置好環境變數後,每次關閉shell視窗後都需要再執行一次source /etc/profile
才能生效,這個問題需要在~/.bashrc
檔案最後新增source /etc/profile
,這樣問題便得到解決
大功告成
