This command can only be run inside of a CLI project

问题

For some reasons, I want to use Angular v5 if I run the below command,it builds an app in angular 6 which I don't want.

ng new hello //this creates angular app in the latest version

I ran the command in the below order

npm init //generated package.json

The above command generated package.json file, I swapped the content of package.json file.

npm install //installed all the node modules

now when I run command to generate the angular component (or any angular enitity) it throws the below error.

This command can only be run inside of a CLI project.

How do I make this app as angular CLI with Angular v5??

回答1:

You can degrade version of cli globally npm install -g @angular/cli@1.7.4. With this cli will generate angular project on version 5.

Or

If you don't want to change your global angular/cli version you can create a new Angular project using npx @angular/cli@1.7.4 new hello.

回答2:

Don't degrade version as in Angular 4+ we don't use new to create new component Instead use generate command to make new component

ng generate component your_Comp_Name
