问一个关于用 Brew 安装 mtr 时的问题

[ShiHou]

个人用的zsh，按照网上的步骤用brew安装mtr

➜ ~ brew install mtr
==> Downloading https://homebrew.bintray.com/bottles/mtr-0.86.yosemite.bottle.ta
Already downloaded: /Library/Caches/Homebrew/mtr-0.86.yosemite.bottle.tar.gz
==> Pouring mtr-0.86.yosemite.bottle.tar.gz
==> Caveats
mtr requires root privileges so you will need to run `sudo mtr`.
You should be certain that you trust any software you grant root privileges.
==> Summary
🍺 /usr/local/Cellar/mtr/0.86: 8 files, 148K
➜ ~ sudo mtr google.com
sudo: mtr: command not found
➜ ~ mtr google.com
zsh: command not found: mtr
➜ ~

唔. 即便按照提示加了sudo，也无法运行mtr

没有修改环境变量?

[xucheng]

mtr 好像在/usr/local/sbin 里

我试了一下，也是不行，/usr/local/sbin下面没有mtr,你应该也是这样

[guojing]

brew update,然后再卸载mtr，然后重新安装就可以了

刚刚试了下，还真是的。不过mtr确实已经安装了，手动做个软链接就行。像这样：
ln -s /usr/local/Cellar/mtr/0.86/sbin/mtr /usr/local/bin/mtr

唔. 解决方案如下

安装完 rehash 一下就行
