将 /bin/sh 中的 python 别名为 python3

问题描述 投票:0回答:1

背景

我正在使用一个涉及 makefile 的包。这些 makefile 通过

/bin/sh
SHELL = /bin/sh
中的
Makefile.common
)将 python 命令发送到终端,命令始终为
python some_script.py ...
。因此,为了这个问题,我们假设我必须坚持
/bin/sh

问题

python-is-python3
已安装:

axel@axel-ThinkPad-X250:~$ sudo apt install python-is-python3

python
python3
以及
~/.bash_aliases
(
~/.profile
) 中
alias python='python3'
的别名,并且在
/bin/bash
中起作用:

axel@axel-ThinkPad-X250:~$ /bin/bash
axel@axel-ThinkPad-X250:~$ python3
Python 3.10.12 (main, Nov 20 2023, 15:14:05) [GCC 11.4.0] on linux

axel@axel-ThinkPad-X250:~$ python

>>> exit()

但不是在

/bin/sh

axel@axel-ThinkPad-X250:~$ /bin/sh
$ python3
Python 3.10.12 (main, Nov 20 2023, 15:14:05) [GCC 11.4.0] on linux

>>> exit()
$ python
/bin/sh: 2: python: not found
$ 

如何让 /bin/sh 理解 python 是 python3?

python-3.x bash ubuntu

所以事实证明,用pip创建虚拟环境后,在

python
中发现了
/bin/sh
。顽固的我。
