On Mac, my particle commands (any of them, including just 'particle') now return this before successfully completing:

> Error loading command /usr/local/lib/node\_modules/particle-cli/commands/CloudCommands.js Error: Cannot find module '/usr/local/lib/node\_modules/particle-cli/node\_modules/serialport/build/serialport/v1.7.4/Release/node-v47-darwin-x64/serialport.node'

Any suggestions?

Thanks

Can you do a `npm uninstall -g particle-cli` and `npm install -g particle-cli` again? Seems like an installation issue

Thanks. I think I had forgotten that I had upgraded to node 5.0.0 and it appears there is a conflict. I downgraded to node 4.2.2 and reinstalled particle and it seems fine.

Hi,  
I’m also facing this issue on node v5.5.0. I tried to uninstall and re-install particle-cli but it still doesn’t work. I get the same exact error message from the first post.

Fixed! I just had to install the node serialport library (`npm install serialport`), remove particle-cli, then re-install.
