WARN Pre-compiled module is missing: usb (it's happening again, sorry) when requiring tessel v0.3.24 #724

Closed sanderblue closed 8 years ago

sanderblue commented 8 years ago

When requiring the latest version of the node module tessel (tessel@0.3.24 node_modules/tessel), I can't deploy my code to Tessel 2.

The code that's causing the main problem seems to be the following. I can build and deploy without issues if I remove this line of code. 

var tessel = require('tessel');

Precompile error

WARN Pre-compiled module is missing: usb

Module error

Error: Cannot find module '/tmp/remote-script/node_modules/tessel/node_modules/usb/src/binding/usb_bindings.node'

This might be caused by any of the following:

1. The binary is platform specific and cannot be compiled for OpenWRT.
2. A pre-compiled binary has not yet been generated for this module.
3. The binary didn't compile correctly for the platform that you're developing on.
    It's possible that the binary is Linux-only or even OpenWRT specific,
    try npm installing with "--force" and rerun your deployment command.

@sanderblue we don't do a great job of documenting this but you don't need to (and shouldn't) 'npm install tessel' into your projects. That module is ready installed on Tessel 2 by default.

Unless you are trying to install the Tessel 1 CLI on your Tessel 2 so you can control your Tessels from your Tessel?

Well clears things up a bit. Thanks for the response. Confirmed this.

Sorry about that - I've created this issue as a potential way to avoid this in the future.
