升级linux python

 

 

 

# python -V # 查看python 版本 # cd /home/centos/Downloads # 进入存放目录 # wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tar.xz # 获取新版的 python # tar xvf Python-3.6.1.tar.xz # 解压文件 # cd ./Python-3.6.1 # 进入解压后的文件目录 # mkdir /usr/local/python3 # 建立编译安装目录 # ./configure --prefix=/usr/local/python3 # 配置编译安装目录 # make && make install # 编译安装 zipimport.ZipImportError: can't decompress data; zlib not available

解决 zipimport.ZipImportError: can't decompress data; zlib not available 的方法：
1.下载源码： http://www.zlib.net/
2.解压安装：

# cd /home/centos/Downloads/

#wget   http://www.zlib.net/zlib-1.2.11.tar.gz
 # tar zxvf zlib-1.2.11.tar.gz # cd zlib-1.2.11 # ./configure # make && make install

从新安装 python3:

# cd /home/centos/Downloads/Python-3.6.1 # ./configure -- prefix=/usr/local/python3 # make && make install # mv /usr/bin/python /usr/bin/python_old # 备份旧的python # ln -s /usr/local/python3/bin/python3 /usr/bin/python # 把新的 python3 连接到 python # python Python 3.6.1 (default, May 30 2017, 18:13:28) # yum search # 安装完后致使 yum 不可用 File "/usr/bin/yum", line 30 except KeyboardInterrupt, e: ^ SyntaxError: invalid syntax

解决 yum 不可用：

# vi /usr/bin/yum #!/usr/bin/python 改为： #!/usr/bin/python_old # yum search
