查看系统python版本
python Python 2.7.9 (default, Mar 1 2015, 18:22:53) [GCC 4.9.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>>
1.更新软件包apt-get update apt-get upgrade
2.安装依赖包aptitude -y install gcc make zlib1g-dev libffi-dev libssl-dev
如果提示-bash: aptitude: command not found,则表示你的机子需要安装aptitude,安装命令如下:apt-get install aptitude
3.下载 Python 3.6.5wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
4.解压压缩包tar -xvf Python-3.6.5.tgz
5.授权文件夹权限chmod -R +x Python-3.6.5
6.进入文件夹,并执行安装配置cd Python-3.6.5/ ./configure
或者将python3安装到其它目录下./configure --prefix=/opt/python3.6.5
会提示以下信息If you want a release build with all optimizations active (LTO, PGO, etc), please run ./configure --enable-optimizations
按照提示进行执行代码,参考链接:http://stackoverflow.com/ques... 注意,如果按照提示执行了代码,那么刚才设置的指定安装路径则无效,会安装到 usr/local/bin 里面。如果你只想用 python3 来执行 flask,那么是否安装到指定目录,对你的目标并没有影响。./configure --enable-optimizations
7.安装依赖包,aptitude -y install libffi-dev libssl-dev
8.编译安装make && make install
显示下面代码则表示安装成功Collecting setuptools Collecting pip Installing collected packages: setuptools, pip Successfully installed pip-9.0.1 setuptools-28.8.0
9.清理配置文件(有没有必要进行这一步,我也不知道。)make clean make distclean
10.添加快捷方式# ln -s /opt/python3.6.5/bin/python3.6 /usr/bin/python3 # ln -s /opt/python3.6.5/bin/pip3.6 /usr/bin/pip3.6 # ln -s /opt/python3.6.5/bin/pip3 /usr/bin/pip3 # ln -s /opt/python3.6.5/bin/pyvenv-3.6
