Cannot install plugin

[PeterHdd]

Hello,

Im executing the command (in ionic app):

 cordova plugin add cordova-plugin-sslcertificatechecker

But I keep getting the following error:

npm ERR! enoent ENOENT: no such file or directory, access '//node_modules/cordova-plugin-sslcertificatechecker'

npm ERR! enoent ENOENT: no such file or directory, access '//node_modules/cordova-plugin-sslcertificatechecker'
npm ERR! enoent This is most likely not a problem with npm itself
npm ERR! enoent and is related to npm not being able to find a file.
npm ERR! enoent

I'm not sure what the problem is, I did npm install cordova-plugin-sslcertificatechecker, also doesnt work, it gives me the same error as above.

Any help is appreciated.

Thank you.
