树莓派3b+编译安装Python3.7.0
原
一、更新树莓派系统
sudo apt-get update
sudo apt-get upgrade
二、安装python需要的依赖
sudo apt-get install build-essential libsqlite3-dev sqlite3 bzip2 libbz2-dev
三、下载Python的源代码并解压
cd mydownload
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz
tar zxvf Python-3.7.0.tgz
四、配置、编译、安装
sudo mkdir /usr/local/python370
sudo ./configure --prefix=/usr/local/python370
sudo make
sudo make install
五、创建符号链接
sudo ln -s /usr/local/python370/bin/python3 /usr/bin/python370
sudo ln -s /usr/local/python370/bin/python3 /usr/bin/python3.7.0
sudo ln -s /usr/local/python370/bin/pip3 /usr/bin/pip370
sudo ln -s /usr/local/python370/bin/pip3 /usr/bin/pip3.7.0
六、测试
python370 --version
树莓派删除Python2.7 默认Python3.7
树莓派自带python2和3版本,要想使用3的话,还得特地敲python3、pip3等等一系列的指令
但是python2我们基本上都已经不学了
所以删除python2.7,输入:
sudo apt-get autoremove python2.7
卸载完后,我们发现想用python3的时候,还得敲python3
想敲python直接出来python3的话,那么先把python链接删掉:
sudo rm /usr/bin/python
载新建一个链接:
sudo ln -s /usr/bin/python3.7 /usr/bin/python
查看版本:
python
显示如下:
-
Python 3.7.3 (default, Apr 3 2019, 05:39:12)
-
