Cannot find module 'nan'

[ktiedt]

npm install nan fixes this, but seems like it should be unnecessary?

[shakogegia]

same to me :(

[CharlieHess]

Yeah, I'm keeping both nan and node-gyp as devDependencies.

@CharlieHess

Yeah, I'm keeping both nan and node-gyp as devDependencies.

Why? It creates headaches for your users. Aren't you just defeating the purpose of the dependency mechanism?

• I added const notifier = require('node-mac-notifier'); resulted in the above error, as my IDE automatically runs npm install for missing modules.
• I ran npm install node-mac-notifier exactly as your README says, and I get

Agreed, these are obviously dependencies and I don't see why you would keep them as devdependencies...

[davethegr8]

I tried to use this library today, but it won't install without the listed nan dependency. I'm not going to manually manage multiple dependencies as that defeats the purpose of listing deps. :(

[strawberry-code]

For newbies, to solve this issue please install missing dependencies, and so:

npm install nan node-gyp

and now you can install the package:

npm install node-mac-notifier 

or using Yarn:

yarn add nan node-gyp
yarn add node-mac-notifier
