Cannot find module 'bluetooth-hci-socket'

I am trying to make bleno work with a raspberry pi 3 and I am getting this error: internal/modules/cjs/loader.js:583 throw err; ^

Error: Cannot find module ‘bluetooth-hci-socket’ at Function.Module._resolveFilename (internal/modules/cjs/loader.js:581:15) at Function.Module._load (internal/modules/cjs/loader.js:507:25) at Module.require (internal/modules/cjs/loader.js:637:17) at require (internal/modules/cjs/helpers.js:22:18) at Object.<anonymous> (/home/pi/Desktop/hwTest/node_modules/bleno/lib/hci-socket/mgmt.js:6:26) at Module._compile (internal/modules/cjs/loader.js:689:30) at Object.Module._extensions…js (internal/modules/cjs/loader.js:700:10) at Module.load (internal/modules/cjs/loader.js:599:32) at tryModuleLoad (internal/modules/cjs/loader.js:538:12) at Function.Module._load (internal/modules/cjs/loader.js:530:3)

I had the same issue on windows but I manged to slove that by installing the package however here when I am trying to install the missing module I am getting this error: npm i bluetooth-hci-socket npm WARN npm npm does not support Node.js v10.15.2 npm WARN npm You should probably upgrade to a newer version of node as we npm WARN npm can’t make any promises that npm will work with this version. npm WARN npm Supported releases of Node.js are the latest release of 4, 6, 7, 8, 9. npm WARN npm You can find the latest version at https://nodejs.org/

Any suggestions?

[deepakvalagam]

Install node version manager:

sudo npm install -g n

Downgrade node to v 8.9.0 by:

sudo n 8.9.0

then

sudo npm install bluetooth-hci-socket --unsafe-perm

[nkemcels]

Or if downgrading nodejs is not an option for you as it was in my case, then use @abandonware/bleno instead.
