Should I install hardhat globally?

[CaledoniaProject]

I'm wondering if I should I install hardhat globally? I installed truffle with -g, I shouldn't install hardhat for each project right?

On the contrary, Hardhat doesn't even work if you install it globally. This is an explicit decision on our part since we think installing tools like this is an anti-pattern, given that it reduces reproducibility among members of the team.

Notice that this is a very common recommendation. For example, from eslint's docs:

It is also possible to install ESLint globally rather than locally (using npm install eslint --global). However, this is not recommended, and any plugins or shareable configs that you use must be installed locally in either case.

Or check Prettier's installation docs, where the possibility of installing it globally is not even mentioned (even if prettier does work in that case).
