tl;dr
n doesn't support windows, or at least not x64 but brodybits on that issue mentioned https://github.com/jasongin/nvs

[zawsx]

Thanks for the response, appreciated! Wish I'd realised that Windows wasn't supported - maybe make the error message clearer?

[j2l]

And still not fixed, or even adding a clearer message in mid 2019.

[shadowspawn]

For the interest of future readers of this closed bug, and for @j2l.

n is written as a bash script. On plain Windows there is no bash shell, so n can not run. What we do is specify in our npm package.json that we do not support Windows, and the error and error message are handled by npm itself. We don't have any control over the message.

[danowar2k]

Could be important: On Windows there is the possibility to execute bash scripts using git for Windows bash or cygwin.

But perhaps there are other reasons n isn't usable on Windows...

[kthorne1]

And exactly how do I find where this is being requested or how can I exclude it. I don't see [email protected] in my package.json nor when I search the entire project. But I'm getting this error on a Windows 10 box and need to resolve it. Thanks

[shadowspawn]

Hi @kthorne1 , you can list dependencies of a package using npm ls, and to see usage of n:

npm ls n

[csaar95]

I got exactly the same error, by running npm install -g n in my git bash. It worked for me to update node with the .msi-installer on nodejs.org.
