linux PATH无法正常工作

Question

我不知道为什么rbenv命令不起作用.T ^ T
只有在＆＃cd; cd /usr/local/.rbenv/bin＆amp;＆amp; ./rbenv'

myggul@ubuntu:~$ echo $PATH
/usr/local/java/bin:/usr/local/.rbenv/bin;/home/myggul/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

myggul@ubuntu:~$ cd /usr/local/.rbenv/bin

myggul@ubuntu:/usr/local/.rbenv/bin$ ll
total 12
drwxrwxr-x 2 myggul myggul 4096 Jul 16 16:11 ./
drwxr-xr-x 7 myggul myggul 4096 Jul 16 16:11 ../
lrwxrwxrwx 1 myggul myggul   16 Jul 16 16:11 rbenv -> ../libexec/rbenv*
-rwxrwxr-x 1 myggul myggul  724 Jul 16 16:11 ruby-local-exec*

myggul@ubuntu:/usr/local/.rbenv/bin$ rbenv

你的PATH中有一个分号，应该是冒号。
