## husky hooks 不生效，不起作用的解决方法。

> [具体办法看文档](https://typicode.github.io/husky/troubleshooting.html)

+ Ensure that you don't have a typo in your filename. For example, `precommit` or `pre-commit.sh` are invalid names. See Git hooks [documentation](https://git-scm.com/docs/githooks) for valid names.

+ Check that `git config core.hooksPath` returns `.husky` (or your custom hooks directory).

+ Verify that hook files are executable. This is automatically set when using `husky add` command but you can run `chmod +x .husky/<hookname>` to fix that.

+ Check that your version of Git is greater than `2.9`.

一般以前生效，新建的项目不生效的原因：大概是因为项目是复制的，文件没有设置可执行，run `chmod +x .husky/<hookname>` to fix that.

## TS2451: Cannot redeclare block-scoped variable 'self'.

如何解决在 service-worker 中 self 类型不正确？可以重新定义 self 类型，重新定义 self 类型的时候报错，加个 export 就好了
```ts
export declare const self: ServiceWorkerGlobalScope & typeof window;
```
