Yikes, I haven't seen this crop up for a while.

brew doctor contains fix instructions, but if you can't execute brew doctor for some reason the answer is sudo chmod +t /tmp unless you've manually set a different HOMEBREW_TEMP.

Thank you very much for helping me resolve this issue. After use brew doctor,l also find other problem, /usr/bin occurs before /usr/local/bin and l found how to resolve it in http://stackoverflow.com/,but l can't find the page now,it say rewrite etc/paths,and list how to rewrite, l just copy it and didn't see if l have the directory. so when l source ~/.bash_profile, many commands l can't use , l found the problem is in the file etc/paths have one path is wrong.l modified this file,and restart computer or restart apache,or source etc/paths,source ~/.bash_profile, it isn't work. The wrong path also in the terminal.

-bash: /usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin: No such file or directory
-bash: /usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin: No such file or directory
-bash: /usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin: No such file or directory

/usr/local/sbin this one
In etc/paths already not exists,l don't understand why still load it when open terminal.
l'm sorry for my poor english, could you give me some suggestions?

echo $PATH
/usr/local/bin:/usr/local/mysql/bin:.

the first is set by etc/profile
the second is set by ~/.bash_profile
so all in the etc/paths isn't work

etc/paths

/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin

[zelsonia]

l know how to resolve it! my bash_profile is wrong too,open it in terminal is different from open in the l don't know how to call it ,the txt editor,maybe.
thank you again.~
