1、问题

[root@centos7 Python-3.9.4]# ln -s python /usr/bin/python
[root@centos7 Python-3.9.4]# python
-bash: /usr/bin/python: Too many levels of symbolic links

 

2、删除建立的软连接

rm -f /usr/bin/python

 

3、以绝对路径建立软连接

[root@centos7 Python-3.9.4]# ln -s /home/software/python/Python-3.9.4/python /usr/bin/python
[root@centos7 Python-3.9.4]# python
