was compiled against different Node.js version

[Karmac]

Hi!

I've been trying to install bleno without success. I'm on a Raspberry PI 3 Model B. First I downgraded Node.js to version 8.15.1 in order to avoid node-gyp compiling error. Now, I get the following when running the program:

App threw an error during load

NODE_MODULE_VERSION 64. Please try re-compiling or re-installing
the module (for instance, using npm rebuild or npm install).

In this one I was using @abandonware's fork. I've also switched versions, and I get the same error (compiled using XX and required version 64). I've already searched on the internet and I don't find any working solution.

If someone could please help me or give some ideas I would appreciate. Everything should work fine here because I've seen bleno installed on Raspberries.

Thanks,

Have seen the same error. On diagnosing, figured that the problem was with using nvm for version management. NVM keeps the node versions in the directory: /usr/username/.nvm which is used for compiling when installing the packages.
Using the bluetooth-hci-socket requires using sudo command, which does not access the Node from nvm path, in stead uses the node version installed for root user.

For me, it appeared like this:
$ sudo node -v
v10.15.3
$ node -v
v9.11.2

Solution

Downgrade the node version for root to Node 8.15.1.

Hi @psambit9791, thanks for your response!

There was a mismatch on both versions. I downgraded NVM version because it was higher. Now I get the following:
node -v
v8.11.1
sudo node -v
v8.11.1

But I still get "Compiled against NODE_MODULE_VERSION 57. This version requires NODE_MODULE_VERSION 64".

I think I will try to uninstall NVM and use only system node.js. I'll let you know if I find something.

Okey, I finally solved the issue. Seems that Node.js version didn't even matter, because Electron uses it's own. I downgraded Electron to 2.0.18 which uses Node 8.9.x.

Thanks for your help.

@Karmac

Can you elaborate more on how you recompile?
