英文:
python makefile can't find python command
问题
On my M2 Mac, Python makefile does not work. I'm running everything in iterm2.
Error when running makefile:
➜ make test-local
/bin/sh: python: command not found
make: *** [test-local] Error 127
Python path:
➜ which -a python
python: aliased to /usr/local/bin/python3.9
➜ python
Python 3.9.17 (main, Jun 20 2023, 17:20:08)
[Clang 14.0.3 (clang-1403.0.22.14.1)] on darwin
Type "help", "copyright", "credits", or "license" for more information.
My .zshrc file. I read other SOF articles so I tried adding to my path to no avail.
alias python=python3
PYTHON="$PATH:/Users/lewis.chi/Library/Python/3.9/bin"
PYTHON1="/usr/local/bin/python3.9"
PYTHON11="/usr/local/bin/"
export PATH=$PATH:$PYTHON:$PYTHON1:$PYTHON11

这是你的问题：
➜ which -a python
python: 别名为 /usr/local/bin/python3.9
这意味着 python 是一个 shell alias。Shell 别名只对你正在使用的 shell 本地，不会导出到子 shell，并且 make 对别名一无所知。因此，你不能在 make 配方中运行别名。
如果你想让这个工作，你必须找到另一种方法。你可以使用一个 make 变量并在命令行上设置它为正确的值，你可以使用一个 python 脚本代替别名，你可以将 python 设置为对 python3 的符号链接，等等。
但你不能使用 shell 别名。
顺便说一下，对于 shell 函数也是一样：它们也只对当前 shell 本地，不会导出到外部。

This is your problem:
➜ which -a python
python: aliased to /usr/local/bin/python3.9
This implies that python is a shell alias. Shell aliases are local to the shell that you're using, they are not exported to sub-shells and make doesn't know anything about aliases. So, you cannot run aliases from within make recipes.
If you want to make this work, you have to find a different way. You can use a make variable and set it to the right value on the command line, you can use a python script instead of an alias, you can make python a symbolic link to python3, etc. etc.
But you cannot use a shell alias.
Ditto for shell functions, by the way: they are also local to the shell and not exported.
