env variable to prevent install

[noamokman]

Hi,
Can we add an env variable to disable the install script?
something like the CI detection.

Let me know if I should open a PR.
Thanks

Hi @noamokman,

What's your use case? Or what issues are you facing?

Alternatively, depending on your use case one of these solutions may work:

• you can use npm install --ignore-scripts but it will ignore all postinstall scripts
• you can only install dependencies and not devDependencies which would prevent install

Yeah,
I use husky on 2 generator project,
A part of the test it to run npm install on an inner folder.
The generated folder then installs husky on a folder with out a .git directory, so it traverses up to the git folder of the generator, this breaks existing hooks.

Adding a new environment variable should be quit simple.
Would be happy to do it for you.

Maybe SKIP_HUSKY_INSTALL.

Thanks!

After giving some thoughts, PR welcome :)

Seems like there was something that was started to control installation:

HUSKY_IGNORE_CI could be refactored to HUSKY_SKIP_INSTALL
