Angular: ng new error when I create an angular project

I have this error using ng new project_name:

An invalid configuration file was found ['angular.json']. Please delete the file before running the command.

I am getting this error I don't know how to get the solution.

I uninstalled @angular/cli and installed again

npm clean cache doesnt work too (I dont know if it is problem of my npm version

npm version is 6.4.1    
node version is 8.11.1

what do i need to solve the problem?

The problem seems to be the _ in project_name resulting in the following error:\n\nSchematic input does not validate against the Schema: {\"name\":\"project_name\",\"version\":\"6.0.1\",\"newProjectRoot\":\"projects\",\"skipInstall\":false,\"linkCli\":false,\"skipGit\":false,\"commit\":null}\nErrors:\n\n Data path \".name\" should match format \"html-selector\".\n\n\nReplace _ e.g. with -.\n\nFurther readings:\n\n\nError when creating new project with Angular-CLI 6.1.2\nStyle Guide\n",

Setting the working directory in IntelliJ's Karma task, to the Angular project's main directory, also fixes the problem.",

I deleted the file in c:\\users\\XXX\\.angular.json and it was running ok.",

Run following if file is hidden. Open Terminal, run mv /Users/shivammishra/.angular.json /Users/shivammishra/angular.json.txt. \nmv command will move the file to new location (angular.json.txt) and you can then delete.",

If you are using the terminal of IntelliJ IDEA while there is a angular project already imported in the IDEA, it is the problem of the IDEA.So, open the command promt of your windows and create the project.\nI did this and I was able to create the project.",
