Mac 终端每次启动都要执行 source .bash_profile

Posted 2020-11-22 n031

网上说法都是

发现zsh加载的是 ~/.zshrc文件，而 ‘.zshrc’ 文件中并没有定义任务环境变量。

但是我搜索zsh找到的只有一个叫做「oh my zsh」的东西，我并没有装这个软件

还有一种说法是修改.profile文件，试过了，不好使

最后我在Stack Overflow上找到了答案

https://stackoverflow.com/questions/15733508/why-do-i-need-to-source-bash-profile-every-time

Now that we‘ve narrowed down the problem:

1. Run ps -p $$ at the command line to determine that you are, in fact, using a bash shell.
2. Realize that you are in zsh, which means you should be editing your profile in .zshrc.
3. Copy the offending lines from .bash_profile to .zsh, OR
4. Modify your .zshrc to directly source your .bash_profile.

执行ps -p $$，发现结果是

  PID TTY           TIME CMD
  692 ttys000    0:00.03 -zsh

好吧。。。虽然不知道是为什么会是zsh，但自此问题解决
