zzw_非root用户安装python3.5

目的：不想改变linux 自带的python,只想要用特定的非root用户运行特定版本的python

1、进入非root用户

2.新建一个python3.5的安装目录

[a4_csbdc@bdc8165 ~]$  mkdir /opt/aspire/product/a4_csbdc/python/python3.5.2

3.解压下载的 python包

[a4_csbdc@bdc8165 pythoninstall]$  tar  -xvf Python-3.5.2.tgz

[a4_csbdc@bdc8165 pythoninstall]$ cd  Python-3.5.2    #进入解压后的目录

4.进行configure

[a4_csbdc@bdc8165 Python-3.5.2]$ ./configure   --prefix=/opt/aspire/product/a4_csbdc/python/python3.5.2    # 重要！！！，--prefix=后面的就是安装目录

5.make

[a4_csbdc@bdc8165 Python-3.5.2]$ make

......

Fatal Python error: Py_Initialize: Unable to get the locale encoding
LookupError: unknown encoding: GB2312

Current thread 0x00002b7164be6050 (most recent call first):
/bin/sh: line 5:  8742 已放弃                  ./python -E -S -m sysconfig --generate-posix-vars
generate-posix-vars failed
make: *** [pybuilddir.txt] 错误 1

出错了：字符编码的问题

[a4_csbdc@bdc8165 Python-3.5.2]$ cat $HOME/.bash_profil

......

export LANG=zh_CN.GBK   #其中有这么一句

.......

6.暂时改变一下字符编码

[a4_csbdc@bdc8165 Python-3.5.2]$  export LANG="en_US.UTF-8"

[a4_csbdc@bdc8165 Python-3.5.2]$ echo $LANG   #确认一下
en_US.UTF-8

7.再来make一下

[a4_csbdc@bdc8165 Python-3.5.2]$ make

........

Python build finished successfully!

8.make install

[a4_csbdc@bdc8165 Python-3.5.2]$ make install

....

Collecting setuptools
Collecting pip
Installing collected packages: setuptools, pip
Successfully installed pip-8.1.1 setuptools-20.10.1

9. 安装完成

10.配置一下环境变量
[a4_csbdc@bdc8165 python3.5.2]$ vi  $HOME/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin
    export PATH
    export PATH=/opt/aspire/product/a4_csbdc/jdk/bin:${PATH}
    export PATH=${PATH}:/opt/aspire/product/a4_csbdc/python/python3.5.2/bin   #在export PATH 之前加入python安装路径
    export JAVA_HOME=/opt/aspire/product/a4_csbdc/jdk
    export CLASSPATH=/opt/aspire/product/a4_csbdc/jdk/lib
    export LC_CTYPE=zh_CN
    export LANG=zh_CN.GBK
    export PATH

alias python="/opt/aspire/product/a4_csbdc/python/python3.5.2/bin/python3.5"  #设置一下别名

注：如果环境变量不配置，则要进入到安装目录/opt/aspire/product/a4_csbdc/python/python3.5.2/bin 中执行命令python3.5

11、生效环境变量

[a4_csbdc@bdc8165 python3.5.2]$ source  $HOME/.bash_profile

12、运行一下

[a4_csbdc@bdc8165 ~]$ python
