Git pre-commit hooks 继续修改文件，即使我暂存了之前修改过的文件

Question

我运行宁gitpre-commit和运行宁黑作为钩子之一

现在当我运行 commit 时，黑色失败并说：

All done! ✨  ✨
15 files reformatted, 1 file left unchanged.

我查看了重新格式化的文件，对它们没有意见。所以我暂存这些文件并再次尝试运行ning commit，但我不断收到与上面相同的消息。我尝试了以下命令但没有成功。

git add .
git add -A
git add -u

这是我的 .pre-commit-config.yaml 文件：

                files: .py$
    -   repo: local
        hooks:
            -   id: tests
                name: run tests
                entry: venv/bin/pytest -v -m fast
                language: python
                additional_dependencies: [pre-commit, pytest]
                always_run: true
                pass_filenames: false
                types: [python]
                stages: [commit]
    -   repo: local
        hooks:
            -   id: tests
                name: run tests
                entry: venv/bin/pytest -x
                language: system
                types: [python]
                stages: [push]

当我执行 git status --short 时，我得到这个：

M  .pre-commit-config.yaml
M  pytest.ini
M  setup.cfg
RM tests/tests_report.html -> tests/commit_pytest_report.html
R  report.html -> tests/commit_tests_report.html
AM tests/coverage/index.html
A  tests/coverage/file_1.png

当我运行git commit -m "test"，运行宁git add .后，git add -A，或git add -u；我明白了：

我不确定自己做错了什么； git 似乎没有用黑色格式更新我的提交。我无法通过 Google 研究找到任何东西。谢谢！

Answer 1

您似乎在同时使用 black 和 double-quote-strings-fixer

前者喜欢python中的双引号字符串（可以通过在pyproject.toml中配置黑色为skip-string-normalization来禁用）
后者喜欢python中的单引号字符串（喜欢双引号的可以去掉）

如果两个格式化程序发生冲突，最终结果将是失败，因为提交前检查以确保一切都已解决
