pre-commit run 路径python3.6（来自--python=python3.6）不存在

Question

我正在尝试遵循JupyterHub的贡献文档，但在运行时出现错误pre-commit run

该错误与我的 python 版本有关。3.6尽管一切都安装了 Python ，但出于某种原因，它仍然在期待3.7.3。这是运行命令的输出：

(.hub)  {~/jupyter/jupyterhub} (master %)$  pre-commit run

Check the log at /Users/nicholasbrady/.cache/pre-commit/pre-commit.log

如果我检查日志，它是这样说的：

(.hub)  {~/jupyter/jupyterhub} (master %)$  cat /Users/nicholasbrady/.cache/pre-commit/pre-commit.log

我试图清除缓存，因为它看起来像是在我使用 python 3.6 时可能存在的缓存

(.hub)  {~/jupyter/jupyterhub} (master %)$  pre-commit clean
Cleaned /Users/nicholasbrady/.cache/pre-commit.

但它根本没有改变错误或日志。

有谁知道这是什么吗？如果没有，希望我能尽快弄清楚，并在我这样做时添加答案...... :)

该存储库的配置设置language_version: python3.6这就是它尝试使用 python3.6 的原因

我建议将其更改为language_version: python3或安装python3.6
