Don't install husky in 'postinstall' if '.git' directory doesn't exists

[mondeja]

I know that this is an edge case, but I found it interesting. If you download the repository using Github UI (Code -> Download ZIP), extract the repository and executes npm install, next error is raised during the installation:

postinstall error

> simple-icons-font@4.9.0 postinstall /.../simple-icons-font-develop
> is-ci || husky install

/.../simple-icons-font-develop/node_modules/husky/lib/commands/install.js:20
        throw new Error(".git can't be found");
        ^

Error: .git can't be found
    at Object.install (/.../simple-icons-font-develop/node_modules/husky/lib/commands/install.js:20:15)
    at Object.<anonymous> (/.../simple-icons-font-develop/node_modules/husky/lib/bin.js:43:19)

Which means that husky needs the .git directory to exist or will fail. I'm sure that no one would do this, only me on Windows 😅, but anyways seems to me that this should be possible because someone could install this only for test it quickly, even if are not planning doing commits.

The proposed change seems counterintuitive but is the most straightforward way of do this: if .git directory does not exists, exits with 0 code and don't executes husky install, otherwise the node -e command fails and husky install is executed.

Interesting 🤣

This really seems more like an upstream issue to me though 🤔 did you investigate if there is any discussion in this regard in the Husky repository? Alternatively, are there no scripts like is-ci to check if the .git repo exists?

This just seems like a very hacky solution for a very niche "problem" (not even really a problem, the dependencies are still installed), and the fact that it is counter-intuitive doesn't add to the appeal 😅

^{I get that that is arguably also true for the is-ci check, but it is actually almost never a problem if you install git hooks in CI, one may just want to disable it because it is pointless}

I've done all this before:

• Nobody has asked never this in husky repository, maybe this form of installation is too weird.
• I haven't found any script to check if .git directory exists. I suppose that the check is too simple that nobody has needed.

I agree, feel free to close this 👍 I will probably open an issue in husky repository to check what their devs have to say about this...

We can leave this open until we get more details from upstream 🙂

Linking typicode/husky#851

Has been fixed in typicode/husky@f8f1afe, so there is no need to do anything here. After 5.0.9 husky will print a message if .git directory is not found instead of raising an error.

Awesome 👍

In my case the problem was happening in in the version 5.1.2 due to a wrong configuration in my package.json:

  scripts: {
     (...),
      "postinstall": "husky install"
  },

This command is automatically added by husky init.

After removing this command, the error disappeared.

   throw new Error(".git can't be found");
