su-oracle后出现 -bash: export: ` ': not a valid identifier

问题描述：

[root@wyu soft]# su - oracle
Last login: Sat Oct  6 10:45:08 CST 2018 on pts/0
-bash: export: ` ': not a valid identifier
-bash: export: ` ': not a valid identifier
-bash: export: ` ': not a valid identifier

 

原因是oracle环境变量后面有空格

[oracle@localhost ~]$ vi .bash_profile
