The configstore randomly throws this error.

.../node_modules/sync-files/node_modules/configstore/index.js:86
    return this.all[key];
                   ^

This bug can be "disabled" by setting --no-notify-update

I have the same issue. It only happens once in a while though. What does --no-notify-update mean?

[AndyOGo]

Please see the usage secrion of the readme https://github.com/byteclubfr/node-sync-files/blob/master/README.md#usage

[wamoyo]

Right, that's the help text. But I don't understand the relationship between that option and this error?

[wamoyo]

It's a great module, by the way! Hasn't given me any other problems ever : ) Even this occasional error messages isn't really a problem, just kind of confusing. Can't tell why it's coming up, or why it only happens sometimes.

[AndyOGo]

Okay. The stack trace above tells you where it comes from. Or just debug it if you want to know, https://github.com/byteclubfr/node-sync-files/blob/master/bin/sync-files.js#L120-L122

btw update-notifier is another package https://github.com/yeoman/update-notifier
