did you run "npm install"?

[Dweep]

Yes, it is not working, same error

[junwu]

how about npm install keytar? and add '--verbose' to check detail error

[Dweep]

Not working, --verbose shows same error

[junwu]

how about upgrading all the lib to latest in your package.json?

[Dweep]

Not working
