问题
My npm version is 5.5.1 and angular cli version is 6.2.1. When I try to create a new project using the command ng new Project_name then it is creating the latest version of angular (in my case it is creating Angular version ^6.1.0). But I want Angular4. My question is how to create this Angualr2/4/5 (specific version instead of the latest version)? I don't think changing the version value in package.json will help in my case because there are some differences in the older versions and the latest 6 version (like the name of one file has been changed from angular-cli.json to anguar.json and not only name but content is also changed.) I've also raised the same question in Angular-cli Github site as well. click here
Thanks in advance!!

Using CLI you can not create specific angular version.
But you can install specific version of angular CLI into particular folder.
For Example :
First create new folder inside any drive. I'm going to create demo folder in D drive. Ex: d:\projects\demo.
Then find this folder inside Command Prompt(cmd) or just type cmd into your created folder addressbar in windows and hit enter.
Now type angular specific version command : npm install @angular/cli@1.7.x for angular 5. and use similar command for other version.
After complete the installation, just create new angular project into your specific folder that you recently install angular. Ex: d:\projects\demo\.
Now create angular project using the command ng new Project_name and it will create your specific angular version Project.
In my example it will create angular 5 project.

The Easy Way:
example:npm install -g @angular/cli@6
here the -g flag tells npm to do this install globally. The 6 on the end tells npm that I want the latest available version 6.
if I want to create a new application for Angular 5 I do this :
> npm install -g @angular/cli@1
> ng new my-ng5-app
Remember, Angular CLI was version 1.7 for Angular 5.
if I want to create a new application for Angular 6 I do this :
> npm install -g @angular/cli@6
> ng new my-ng6-app
if I want to create a new application for Angular 7 I do this :
> npm install -g @angular/cli@7
> ng new my-ng7-app
i hope it would be helpful for you thanks....!

this should work
Use a package called npx npm i -g npx and when you need to create an angular project use this command the first time npx -p @angular/cli ng new hello-world-project
after that you can use normal commands to work like ng g c abc

Create a package.json file then define the angular version you want to install then run npm install it will create project in the required version irrespective of the global angular cli
