linux更新python3.7

1.官網下載對應的安裝包

wget https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tgz

2.解壓

tar -zvxf Python-3.7.5.tgz

cd Python-3.7.5

mkdir /usr/local/python3.7

3.然后編譯安裝

./configure --prefix=/usr/local/python37

make &&make install

4.建立python3的軟連接

ln -s /usr/local/python37/bin/python3  /usr/bin/python

python -V

 

5.解決一下yum 不可用這個問題

vi /usr/bin/yum

把文件頭部的

!/usr/bin/python 改成 !/usr/bin/python2.7
