Cannot find module after compiling

jeroen13 commented 4 years ago

I've tried to use the main branch, as well as the windows branch (I assume that it is still being developed)

After installing 'node-mtp' I cannot use it in node.js.

C:\Users\Jeroen\Documents\Development\mtp>node index.js
internal/modules/cjs/loader.js:751
  return process.dlopen(module, path.toNamespacedPath(filename));
                 ^

Error: Cannot find the module.
\\?\C:\Users\Jeroen\Documents\Development\mtp\node_modules\node-mtp\build\Release\module.node`
    at Object.Module._extensions..node (internal/modules/cjs/loader.js:751:18)
    at Module.load (internal/modules/cjs/loader.js:620:32)

    at Module._compile (internal/modules/cjs/loader.js:722:30)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:733:10)

Please note the path starts with: \\?C\the-rest-of-the-path

Has it something to do with the \\? The module.node exists in the path: C:\Users\Jeroen\Documents\Development\mtp\node_modules\node-mtp\build\Release\module.node

Also with normal npm install node-mtp it cannot find the module.node Using latest W10 X64

Thanks in advance!

Hi Jeroen! Yes, I'm still working on adding Windows support. The "cannot find the module" error means that there's a .dll missing (specifically the libusb.dll), which I still need to add to the npm module.

Note that there's a caveat on Windows: node-mtp is a wrapper around libmtp, which uses libusb instead of the Windows MTP drivers to work. This means you'll have to install a libusb-win32 driver for the device you want to connect to, which can be done with https://zadig.akeo.ie/

Does this mean that a realease-version requires the user to install libusb or is this handled inside the module?

It will require the user to install a USB driver ( which can be done using Zadig) that will replace the built-in Windows MTP driver. libusb itself will be handled inside the module. Once I get Windows support working properly, I'll try to write up everything in the README.

More details on Windows USB drivers and libusb are available here: https://github.com/libusb/libusb/wiki/Windows#how-to-use-libusb-on-windows

@jeroen13 Can you try npm install node-mtp again, as I think all the relevant .dll's should now link correctly in v0.3.18?
