Importing API?!

[RPGFabi]

Hey,
I'm trying to import the API but getting this error:
"import clashApi from 'clash-of-clans-api';
^^^^^^

SyntaxError: Cannot use import statement outside a module
at wrapSafe (internal/modules/cjs/loader.js:1063:16)
at Module._compile (internal/modules/cjs/loader.js:1111:27)
at Object.Module._extensions..js (internal/modules/cjs/loader.js:1167:10)

at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:71:12)
at internal/main/run_main_module.js:17:47"

My Code is:
"client.once('ready', () => {
console.log("I'm now Ready to go!")

import clashApi from 'clash-of-clans-api';
let client = clashApi({
    token: CoCAPIToken
});
}

})"

const clashApi = require('clash-of-clans-api');
let CoCClient = clashApi({
token: CoCAPIToken
})

works
