如何在Linux系统中将Python更新至3.7版本

1,下载python3.7包

wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tgz

其他版本下载&＃xff1a;https://www.python.org/downloads/source/

2,解压

tar zxvf Python-3.7.3.tgz
cd Python-3.7.3


3,编译

yum install gcc # 如果没有c编译器的话&＃xff0c;安装
./configure --with-ssl
make
sudo make install


注意&＃xff1a;–with-ssl必须加上&＃xff0c;否则使用pip安装第三方包时&＃xff0c;会引发ssl错误。导致无法使用。如果执行pip install出错&＃xff0c;重新编译安装即可。

错误解决&＃xff1a;

ZipError&＃xff1a;sudo apt install zlib*ImportError:&＃39;_ctypes&＃39;sudo apt-get install python-dev python-setuptools python-pip python-smbus build-essential libncursesw5-dev libgdbm-dev libc6-dev zlib1g-dev libsqlite3-dev tk-dev libssl-dev openssl libffi-dev


python3.7位置

whereis python3.7


4,创建软连接

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


4.2你也可以先将原来的软连接删除&＃xff0c;再创建新的连接

sudo rm -rf /usr/bin/python3
sudo rm -rf /usr/bin/pip3
