Ubuntu16下安装python3.6

1.下载python3.6的包

在终端中输入下面的命令

1. wget http://www.python.org/ftp/python/3.6.4/Python-3.6.4.tgz  
2. tar -xvzf Python-3.6.4.tgz  
3. cd Python-3.6.4  

4. ./configure --prefix=/opt/python3.6  #指定安装目录

5. ./configure --with-ssl                   #指定用ssl功能，要不然pip安装功能不好用
6. make  
7. sudo make install  

2 装好后，将 /opt/python3.6/bin 加入 PATH，如下，

    

export PATH=/opt/python3.6/bin:$PATH

3 如果要安装对应于 Python3.6 的软件包，则要使用 pip3.6，添加如下语句到 .bashrc，

    

alias "pip3.6"="python3.6 -m pip $1"

4，可能在安装过程中会出现下面错误

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

解决办法

apt-get install zlib*

5,如下出现如下错误，有可能缺少和ssl相关的包

pip is configured with locations that require TLS/SSL, however the ssl modul

解决：apt-get install libssl-dev
