umami: eslint error for 1.24 - unable to install/build

Hi I tried to update to 1.24.0 and got a lot of errors from eslint … To find a solution, I tried to remove the umami folder, cleered the npm cache and start from the begining, but I still got a blocking error :

Firefly:~/umami$ npm install

I’m not very familiar with npm.
