Can't install imagePicker plugin

Good Evening,

i can’t install the plugin for ImagePicker, here an extract of the message error:

(node:8144) UnhandledPromiseRejectionWarning: CordovaError: Failed to fetch plugin via registry.
Probably this is either a connection problem, or plugin spec is incorrect.
Check your connection and plugin name/version/URL.
Error: cmd: Command failed with exit code 1 Error output:
npm ERR! code ENOGIT

npm ERR!
npm ERR! Failed using git.
npm ERR! Please check if you have git installed and in your PATH.

npm ERR! A complete log of this run can be found in:

i checked some messages with the same problem but i got no obvious solution.
i tried some links for the plugin but in vain.

Need you help !
