Error: Cannot find module 'nan'

Question

I'm working on native Node.js addon and following nan docs

I included nan into binding.gyp like: "include_dirs" : [ "<!(node -e \"require('nan')\")" ]

Also nan is in npm dependencies.

But when I install the package inside the another node module node-gyp is failed with error

module.js:338
    throw err;

Answer 1

In my case, it was because of some dependencies missing in the package-lock file. I solved it by removing it and running $ npm install again.

Answer 2

Install nan globally:

npm i -g nan

And then,

export NODE_PATH=$(npm root -g)

Answer 3

Not ideal but it works if you install nan first.

$ npm install nan
