我不确定这是否是我应该在官方存储库问题中发布的内容(我有时会在那里看到"question"标签(。但如果你认为这是问这个问题的合适地方，如果有人能帮我，那就太好了。
我一直试图在overcommitgem中添加一个自定义脚本，但没有成功。它在官方文件中说的是在overcommit.yml:中添加行
PostCheckout:
CustomScript:
enabled: true
required_executable: './bin/custom-script'
(所以我这么做了：(
PrePush:
customHook:
enabled: true
required_executable: 'custom-hook'
并将脚本放在项目根目录下的.git hooks目录中。所以我把这个脚本放在.git hook目录中进行测试：
#custom-hook.sh
echo hey
这是一条甜蜜的错误消息：
Hook must specify a `required_executable` or `command` that is tracked by git (i.e. is a path relative to the root of the repository) so that it can be signed

很明显，它抱怨找不到可执行文件，所以我猜格式不对，但信息很少，我陷入了困境。
从错误消息中可以看出，custom-hook必须相对于git存储库的根目录。也许试着把那个放进./bin/custom-hook？
