How I can install a previous version of Angular project with the current Angular-cli version (Angular 6).
I found a command but is deprecated:
ng new my_project --ng4
回答1:
Since you want to use angular-cli to create new project, you need to install the version of @angular/cli that scaffolds angular 4 project.
Version of @angular/cli which scaffolds the Angular 4 project is 1.4.9.
So, using npm, do npm install @angular/cli@1.4.9, then use angular-cli commands.

You can just have package.json with specific version and do npm install and it will install that version. Also you dont need to depend on angular-cli to develop your project.
Other thing is you can remove the latest version of angular-cli and install minor version of it. Then create the project.
Let me explain:
[STEP 0 - OPTIONAL] If you're not sure of the angular-cli version installed in your environment, uninstall it.
npm uninstall -g @angular/cli
Then, run
npm cache clean
or, if you're using npm > 5
npm cache verify
[STEP 1] Install an angular-cli specific version
npm install -g @angular/cli@wished.version.here
[STEP 2] Create a project
ng new you-app-name
The resulting white app will be created in the desired angular version.

I found a better answer for me. I share it with you:
How to install Angular 2:
npm install @angular/cli@1.0.0-beta.33.1 This install the 2.4.0 version
How to install Angular 4:
npm install @angular/cli@1.4 This install the 4.2.4 version
How to install Angular 5:
npm install @angular/cli@1 This install @angular/cli@1.5
All this installations it must be installed as local projects dependencies
I hope you find it useful.
