Mac 使用 homebrew 安装 git 为啥无法替换系统自带的 git？

[turandot]

尝试了各种方法无果，设置如下：

1./etc/paths：
/usr/local/bin
/usr/local/sbin
/usr/bin
/bin
/usr/sbin
/sbin

2.~/.bash_profile和~/.profile都留空 [之前尝试这两个文件加入环境变量无果]

3.echo $PATH
/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin

4.git --version
git version 1.9.3 (Apple Git-50)

还是自带的版本，brew安装的2.1.3未生效

[hzlez]

$ which git
/usr/local/bin/git

你brew install的git在不在/usr/local/bin中呢。

[turandot]

@hzlez
##我brew install 的git在/usr/bin/中。

[turandot]

@hzlez

➜ ~ brew list
git openssl wget
➜ ~ which openssl
/usr/bin/openssl
➜ ~ which wget
/usr/local/bin/wget
➜ ~ which git
/usr/bin/git

这是啥情况？为毛git和openssl在/usr/bin/但是wget在/usr/local/bin/？

[ooxxcc]

brew info git呢

你有没有brew link git

[ooxxcc]

另外看一下/usr/local/sbin/git存在不存在

[turandot]

@ooxxcc

没有brew link git，想的是设置好环境变量后通过brew install的都可以覆盖系统自带的

[goofansu]

.bash_profile里要加一句话的

[turandot]

@goofansu
是echo export PATH='/usr/local/bin:$PATH' >> ~/.bash_profile吗？
每次brew update后brew doctor都会提示，设置似乎只对当前生效，每次update后都要再来一遍...

[turandot]

奇了怪了，reopen一下iterm，没有动任何设置，居然又发生了变化：
➜ ~ cat /etc/paths
/usr/local/bin
/usr/local/sbin
/usr/bin
/bin
/usr/sbin
/sbin
➜ ~ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
➜ ~ git --version
git version 1.9.3 (Apple Git-50)

echo $PATH的结果和之前不一样了

[turandot]

#update

好像是因为ohmyzsh的配置文件也设置了环境变量...

[jsfaint]

楼主你用的是zsh，PATH修改应该在.zshrc里面吧

[ooxxcc]

@turandot 你不link的话/usr/local/bin根本不会有git，你怎么设置PATH都没用啊

除非你把 /usr/local/Cellar/git/2.1.3 添加到PATH变量

另外你用zsh调什么.bash_profile

槽点太多……

[ooxxcc]

楼下可以散了

[canautumn]

把环境变量加到.zshrc里，不要加到.bash_profile里

[turandot]

@ooxxcc
@canautumn
哈哈，惭愧惭愧...,之前一直用bash...
修改.zshrc搞掂了

[kqz901002]

@turandot 修改.zshrc

[kqz901002]

@turandot = = 两天前de 帖子。。。。

[turandot]

@kqz901002 嗯嗯，已经可以愉快的玩耍了，anyway，还是thx了
