Module version mismatch. Expected 48, got 47.

Hello,

when I run dredd command I’m getting ‘Module version mismatch. Expected 48, got 47.’ error.

Node version is 6.1.0. and npm 3.8.6.

Complete error message:

module.js:568
  return process.dlopen(module, path._makeLong(filename));
                 ^

Error: Module version mismatch. Expected 48, got 47.

What should I do to fix this?

Thank you

This sounds like you’ve installed dredd and then upgraded or changed the version of node you are using. To solve this, you will need to reinstall dredd with the version of node you want to run it from.

$ npm install -g dredd

@asbjornu @alexey-sh Did you try the solutions mentioned above? You could also give a try to the pure JS version to avoid compilation:

$ npm uninstall dredd
$ npm install dredd --no-optional
