Not compatible with your operating system or architecture: [email protected]

Question

I'm using Ubuntu 15.04. While running the following command:

npm install fsevents

I'm getting following error:

npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: [email protected]
npm WARN [email protected] No repository field.

Has anybody solved this?

Answer 1

I was facing the same issue with this dependecy when building other application.

Just for the sake of knowledge and to people who are not well used to NPM, and thus uncertain about how their applications will behave:

Since fsevents is an API in OS X allows applications to register for notifications of changes to a given directory tree. Running:

npm install --no-optional

Will do the trick, with no drawbacks.

Answer 2

It's not an error, it's just a warning: it's an optional dependency.

Answer 3

You can tell npm not to install optional dependencies by default using the command line below:

npm config set optional false

Answer 4

If you're getting ERR! not WARN a likely cause of this issue is that you're using a really outdated version of NPM

For me, I shelled into some server, and was like "why won't this work?", getting this error:

npm ERR! Linux 4.4.0-130-generic
npm ERR! argv "/home/william/.nvm/versions/node/v4.4.3/bin/node" "/home/william/.nvm/versions/node/v4.4.3/bin/npm" "install"

Turns out this server (that I only recently acquired) was running npm 2.15.1. I re-installed nvm, and nvm install --lts fixed it.
