python升級2.6到2.7 和 pip的安裝

安裝依賴, 解決一些奇怪的問題

例如安裝pip時遇到:

Traceback (most recent call last): 
  File "<string>", line 1, in <module> 
zipimport.ZipImportError: can't decompress data; zlib not available 

 

yum -y install gcc gcc-c++  make automake autoconf kernel-devel ncurses-devel libxml2-devel openssl-devel curl-devel libjpeg-devel libpng-devel  pcre-devel libtool-libs libtool-ltdl-devel freetype-devel gd zlib-devel file bison patch mlocate flex diffutils   readline-devel glibc-devel glib2-devel bzip2-devel gettext-devel libcap-devel libmcrypt-devel

 

 

安裝python2.7

下載2.7源碼

　　wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz

解壓

　　tar -xf ./Python-2.7.13.tgz

創建文件夾

　　mkdir /usr/local/python2.7/

安裝

　　cd ./Python-2.7.13
　　./configure  --prefix=/usr/local/python2.7/

備份當前版本

　　mv /usr/bin/python /usr/bin/python_bak

建立新版本軟鏈接

　　ln -s /usr/local/python27/bin/python2.7 /usr/bin/python

檢查版本

　　python -V

 

安裝pip

下載安裝腳本

　　wget --no-check-certificate https://bootstrap.pypa.io/get-pip.py

安裝

　　python get-pip.py

copy pip腳本到bin(可以先檢查是否已經存在pip命令)

　　cp /usr/local/python27/bin/pip /usr/bin/pip
