npm-autoinstaller - Migrating

Due to the fact that there can only be one git-hook for each action, you may receive this message during installation if you already use another package with git-hooks: it seems like you already have some git hooks installed.

There is no universal way to solve this problem, but here is some help:

You used a package with git-hooks before but you don't need it anymore

If this is the case, simply delete these files (if they exist):

.git/hooks/post-checkout
.git/hooks/post-merge
.git/hooks/post-rewrite

And execute the following commands:

cd node_modules/npm-autoinstaller
node install.js

The hooks should now be installed like during a normal npm install.

You use a package for managing multiple git-hooks

When using a package for managing multiple git-hooks, for example git-hooks, you can manually add the hooks of this package. The following scripts have to be called:

node node_modules/npm-autoinstaller/dist/hooks/post-checkout "$@"
node node_modules/npm-autoinstaller/dist/hooks/post-merge "$@"
node node_modules/npm-autoinstaller/dist/hooks/post-rewrite "$@"

Note that if your script manager invokes additional scripts via the scripts in the .git/hooks folder, and you are adding the above commands to these scripts, you will need to pass hook parameters through to the script you are adding the above lines to. For example, the husky hook manager configures its scripts in package.json, and provides the git hook parameters as $GIT_PARAMS:

{
    "scripts": {
        "postcheckout": "node ./hooks/post-checkout.js $GIT_PARAMS"
    }
}

You use another package

If you are using another package, you can try to manually add the three commands above to the already existing git-hooks file in .git/hooks. But depending on which package you have, they may get overwritten on the next install.
