shell登录后,为什么$ PATH会被覆盖？

Question

在这里似乎有一百个关于如何在Mac OS X/Linux环境中改变你的路径的问题....事实上,我认为实际上知道如何更改我的PATH变量,但似乎有些事情导致它被覆盖.我正在使用zsh并且试图Brew Doctor不警告我在user/local/bin之前使用usr/bin.我的〜/ .zprofile:

export PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
echo $PATH

登录后我得到:

Last login: Fri Oct 17 15:10:30 on ttys000
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

但是在登录后运行$ PATH我得到:

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

我正在直接登录到zsh但是为了防止我的.profile和.bash-profile都包含与我的.zprofile相同的代码,并且我的/etc/paths.d目录中没有任何内容.是否有其他地方设置了PATH？我在这里错过了什么？

用户应注意/ etc/profile设置$ PATH变量,该变量将覆盖〜/ .zshenv中设置的任何$ PATH变量.为防止这种情况,请在〜/ .zshrc中设置$ PATH变量.(不建议将/ etc/zsh/zprofile中的默认行替换为其他内容,它会破坏在/etc/profile.d中提供某些脚本的其他包的完整性)

For zsh: [Note that zsh seems to read ~/.profile as well, if ~/.zshrc is not present.]

Moral:
For bash, put stuff in ~/.bashrc, and make ~/.bash_profile source it.
For zsh, put stuff in ~/.zshrc, which is always executed.
