安装python3.6可能使用的依赖
# yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel
下载python3.6编译安装
到python官网下载https://www.python.org
下载最新版源码,使用make altinstall,如果使用make install,在系统中将会有两个不同版本的Python在/usr/bin/目录中。这将会导致很多问题,而且不好处理。
# wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz
# tar -xzvf Python-3.6.0.tgz -C/tmp
# cd/tmp/Python-3.6.0/
把Python3.6安装到/usr/local 目录
# ./configure --prefix=/usr/local
# make
# makealtinstall
python3.6程序的执行文件:/usr/local/bin/python3.6
python3.6应用程序目录:/usr/local/lib/python3.6
pip3的执行文件:/usr/local/bin/pip3.6
pyenv3的执行文件:/usr/local/bin/pyenv-3.6
更改/usr/bin/python链接
# cd/usr/bin
# mv python python.backup
# ln -s /usr/local/bin/python3.6 /usr/bin/python
# ln -s /usr/local/bin/python3.6 /usr/bin/python3
更改yum脚本的python依赖
# cd /usr/bin
# ls yum*
yum yum-config-manager yum-debug-restore yum-groups-manager
yum-builddep yum-debug-dump yumdownloader
更改以上文件头为
#!/usr/bin/python改为#!/usr/bin/python2
修改gnome-tweak-tool配置文件
#vi /usr/bin/gnome-tweak-tool
#!/usr/bin/python改为#!/usr/bin/python2
修改urlgrabber配置文件
# vi /usr/libexec/urlgrabber-ext-down
#!/usr/bin/python改为#!/usr/bin/python2
