预提交：提交新文件时找不到可执行文件 python

Question

我正在尝试在 Ubuntu 22.04.1 / Python 3.10.6 上使用预提交2.20.0。

我按照https://pre-commit.com/#installation的说明安装了pre-commit pip (22.2.2)。

这是我的.pre-commit-config.yaml文件：

$ cat /home/username/Projects/web/app/.pre-commit-config.yaml

default_language_version:
    python: python3.10

repos:
  - repo: https://github.com/pycqa/isort
    rev: "5.10.1"
    hooks:
      - id: isort
        args: ["--profile", "black"]

  - repo: https://github.com/psf/black
    rev: "22.8.0"
    hooks:
      - id: black
        language_version: python3.10

但是在提交新文件时遇到错误：

$ git commit -m "Update file."
[INFO] Installing environment for https://github.com/pre-commit/pre-commit-hooks.
[INFO] Once installed this environment will be reused.
[INFO] This may take a few minutes...
An unexpected error has occurred: CalledProcessError: command: ('python', '-mpip', 'install', '.')
return code: 1
expected return code: 0
stdout:
    Executable `python` not found
stderr: (none)
Check the log at /home/username/.cache/pre-commit/pre-commit.log

使用虚拟环境（ virtualenv 20.16.5 ）时也会出现同样的错误：

$ virtualenv venv

  creator CPython3Posix(dest=/home/username/Projects/web/app/venv, clear=False, no_vcs_ignore=False, global=False)

这是完整的日志：

$ cat /home/username/.cache/pre-commit/pre-commit.log

pre-commit version: 2.20.0

sys.platform: linux

### error information is the same as here above

这是我的venv/文件夹结构：

6 directories, 19 files

...根据https://github.com/pypa/virtualenv/issues/2350 ，这可能是造成麻烦的原因，但我绝对不能理解所有的故事。

更多的：

$ which python # empty result!

$ which python3
/usr/bin/python3

$ ls -l /usr/bin/python3
(...) /usr/bin/python3 -> python3.10

我是否错过了预提交安装中的某些内容？
如果可能的话，我怎样才能正确而简单地（#basic 用户）修复这个错误？
