安装python3 zlib必须先安装

1、python查看之前的版本

python --version

(以下操作都是在root用户下或者sudo执行)

 

2、安装python3.6的依赖包

     yum -y groupinstall "Development tools"

 

3、安装其他依赖包

     yum -y install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel

 

4、python3.6下载

　　如果安装其他版本，可去官网直接下载

      wget   https://www.python.org/ftp/python/3.6.4/Python-3.6.4.tar.xz

 

5、创建文件夹

　　mkdir /usr/local/python3

 

6、解压python3.6安装包

      tar -xzjf Python-3.6.4.tar.xz

      

7、设置安装路径

　　cd Python-3.6.4

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

 

8、编译并安装python

　　 如果编译时遇到问题，百度一下就能找到

        make && make install

 

9、设置软连接到/usr/bin目录

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

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

至此安装成功

 

 

一、zipimport.ZipImportError: can't decompress data; zlib not available

解决方法：

$ tar -xzvf ./Python-3.6.1.tgz
$ cd ./Python-3.6.1
$ ./configure
$ make
$ sudo make install

File"/home/lanhaixuan/Python-3.6.1/Lib/runpy.py", line 193, in_run_module_as_main

File"/home/lanhaixuan/Python-3.6.1/Lib/runpy.py", line 85, in_run_code
exec(code,run_globals)

ensurepip._main()

import pip
zipimport.ZipImportError:can't decompress data; zlib not available
Makefile:1064:recipe for target 'install' failed

make: *** [install]Error 

1.重点修改：Modules/setup.dist文件

#zlibzlibmodule.c -I(prefix)/include?L(exec_prefix)/lib -lz   注释取消

#eadlinereadline.c -lreadline -ltermcap注释取消解决乱码问题

     2.安装zlib

$ tar -xzvf ./zlib-1.2.11.tar.gz$ cd ./zlib-1.2.11
$ ./configure$ make
$ sudo make install

然后再次回到python主目录

#make

#make install
