预提交失败，并显示“需要配置映射，但获得了列表”

Question

我已经使用这个pre-commit工具很多年了！它一直工作得很好，直到最近它开始失败并出现一条神秘的错误消息：

$ pre-commit run flake8 --all-files
An error has occurred: InvalidConfigError: 
==> File .pre-commit-config.yaml
=====> Expected a Config map but got a list
Check the log at /home/asottile/.cache/pre-commit/pre-commit.log

我该如何解决？

Answer 1

自 2020 年 7 月以来，您的具体情况一直受到警告，并显示类似以下消息：

$ pre-commit run flake8 --all-files
[WARNING] normalizing pre-commit configuration to a top-level map.  support for top level list will be removed in a future version.  run: `pre-commit migrate-config` to automatically fix this.
flake8...................................................................Passed

幸运的是，即使您已经升级到 pre-commit 3.0（放弃了对此格式的支持），您仍然可以运行pre-commit migrate-config它将您的配置更新为支持的格式：

$ pre-commit migrate-config
Configuration has been migrated.
$ pre-commit run flake8 --all-files
flake8...................................................................Passed
