Ubuntu16.04更新python3.5到python3.7

命令：

下载
wget https://www.python.org/ftp/python/3.7.1/Python-3.7.1rc2.tgz

解压
tar zxvf Python-3.7.1rc2.tgz
cd Python-3.7.1rc2

编译
./configure
make
make install

先找的python3.7解释器位置，一般是
/usr/local/bin/python3.7

删除原来的软连接
rm -rf /usr/bin/python3
rm -rf /usr/bin/pip3

#添加python3的软链接
ln -s /usr/local/bin/python3.7 /usr/bin/python3
#添加 pip3 的软链接
ln -s /usr/local/bin/pip3.7 /usr/bin/pip3

 

报错解决

1、make install 时：报错ModuleNotFoundError: No module named '_ctypes'

补全配置

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get install build-essential python-dev python-setuptools python-pip python-smbus
sudo apt-get install build-essential libncursesw5-dev libgdbm-dev libc6-dev
sudo apt-get install zlib1g-dev libsqlite3-dev tk-dev
sudo apt-get install libssl-dev openssl
sudo apt-get install libffi-dev

清理

sudo apt autoremove
