Error in particle cli: Cannot find module 'core-js/modules/es.array.index-of' [SOLVED]

General

I’ve been working with my Particle Photon but for some reason today I’ve been unable to run any particle command.

And after trying to flash my Particle Photon, I saw this output from CLI in Windows 10:

 !   Error in particle-cli:
 !   Cannot find module 'core-js/modules/es.array.index-of'
 !   See C:\Users\general_user\AppData\Local\particle\error.log for more info.

Look for the error.log file and this was the output:

And looking for a solution here on the community I tried with this commands:

sudo npm uninstall -g --unsafe-perm particle-cli
sudo npm install -g --unsafe-perm particle-cli

but getting the same results setting them as administrator or without being administrator and this was the last messages from cli after execute sudo npm install -g --unsafe-perm particle-cli

> node postinstall

What should I do? Should I reinstall the particle CLI? Thanks!

I basically reinstalled with the Particle CLI Installer and the problem was solved.

On Windows you should not use npm to install/update/uninstall CLI.

  • To install you'd use the Installer (as you have done).
  • To update you should use particle update-cli.
  • To uninstall you'd use Windows' own Add/remove program feature.

Also don't run CLI from a system directory like C:\WINDOWS\System32.
Always move to a user writable folder otherwise some commands will fail due to lack of privileges (even if you are on a Administrator account).

BTW, AFAICT Windows command line would not support sudo, so not sure what you tried but I doubt it was

You are right.

What I typed in the CLI was:

npm uninstall -g --unsafe-perm particle-cli
npm install -g --unsafe-perm particle-cli

instead of:

sudo npm uninstall -g --unsafe-perm particle-cli
sudo npm install -g --unsafe-perm particle-cli

Since on Windows 10 there's no sudo commands available.
