Python升级3.8版本完整教程,避免踩坑

Metabok Lv1

有些linux服务器默认是python2.7版本的,需要升级到3.8版本以上才能更好的服务,我在升级的过程中踩了一些坑。比如各种依赖没有,各种莫名其妙的报错。整理了一份完美无脑升级的连环命令,依次输入运行就可以了。

首先安装一些依赖,必须要做这一步,不然就会出现你在升级的时候莫名其妙的报错

Ubuntu/Debian:

1
sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev python-openssl

Fedora/CentOS/RHEL:

1
sudo yum install zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel openssl-devel xz xz-devel libffi-devel

下载python3.8安装包

1
2
3
wget https://www.python.org/ftp/python/3.8.3/Python-3.8.3.tgz

tar -xvf Python-3.8.3.tgz

创建安装目录

1
mkdir /usr/lib/python3.8

开始安装python(使用make安装)

1
2
3
4
5
6
7
cd Python-3.8.3

./configure --with-ssl --prefix=/usr/lib/python3.8

make

sudo make install

回到主路径

cd

创建默认python链接

1
2
3
4
5
ls -l /usr/bin/python

sudo rm /usr/bin/python

ln -s /usr/lib/python3.8/bin/python3 /usr/bin/python

创建默认pip链接

1
2
3
sudo rm /usr/bin/pip

ln -s /usr/lib/python3.8/bin/pip3 /usr/bin/pip

至此,完成。现在你可以输入python来查看是否是3.8版本。
