虛擬機器安裝的linux 6.7版本，自帶的python是2.6

[[email protected] ~]# python -V  ----檢視python版本

[[email protected] ~]# yum install python-pip

[[email protected] ~]# pip install ipython

[[email protected] ~]# pip install ipython==1.2.1 --指定版本安裝ipython

==========================

現在需要升級python版本 到3.6.1

步驟如下

[[email protected] ~]# cd  /usr/local/src  #進下載目錄

# 下載python-3.6.1

[[email protected] src]# tar xvf Python-3.6.1.tar.xz   #解壓安裝包

[[email protected] src]# cd Python-3.6.1

[[email protected] Python-3.6.1]# ./configure --prefix=/usr/local/python3 #配置編譯安裝目錄

[[email protected]

[[email protected] Python-3.6.1]# make install

編譯時出現報錯：

                          zipimport.ZipImportError: can‘t decompress data; zlib not available

[[email protected] src]# cd zlib-1.2.11         

[[email protected] Python-3.6.1]# ./configure      #編譯

[[email protected]

[[email protected] Python-3.6.1]# cp   /usr/local/python3/bin/python3   /usr/bin/python3

[[email protected] Python-3.6.1]# ln -s /usr/local/python3/bin/python3  /usr/bin/python3

[[email protected] Python-3.6.1]# python -V
