ZepKit: `zos init zepkit` failes (scrypt compiled against a different Node.js version)


#1

Hello,

I am not able to run zos init zepkit on my machine. I followed all the instructions I have found.

The error is as follows:

$ zos init zepkit
internal/modules/cjs/loader.js:718
  return process.dlopen(module, path.toNamespacedPath(filename));
                 ^

Error: The module '\\?\C:\Users\...\AppData\Roaming\npm\node_modules\zos\node_modules\scrypt\build\Release\scrypt.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 59. This version of Node.js requires
NODE_MODULE_VERSION 64. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or `npm install`).

any suggestions how to solve that?

Hello! Thanks for using the forum!

Think you can try npm install? What node version (node --version) are you using?

Thanks!

I don’t think that solves my problem:

Hello @marc0olo, can you try npm install -g zos please? It appears your global zOS is having the issue.


#5

as far is I know I already did that because I saw that.

any other suggestions?


#6

Hey @marc0olo have you tried running npm rebuild as the error message suggests?


#7

I am quite sure I did all suggested steps. But when I find time I will try again just to be sure.


#8

As Ivan suggested, it seems like you have installed zos globally with an older version of node, and now that you have a new one it’s causing this conflict. I’d try uninstalling and installing globally again from scratch.

ok thanks @IvanTheGreatDev and @martriay. it was definitely necessary to uninstall and reinstall zos globally :slight_smile:
