I've just started working with Angular and with Angular-CLI and I've seen that, according to the documentation, I need to install $ npm install -g @angular/cli
with the -g
(global) flag.
However I would like to have Angular-CLI installed locally with the rest of my node_modules packages. This way, when I've download my project from git, I could simply run $ npm install
(for installing all the dependencies in my package.json).
I try to create a new project by running $ npm init
and then run $ npm i @angular/cli -D
(-D
is the same as --save-dev
). But then when I run $ ng new project-name
a new sub directory was created with a separate node_modules directory.
As some of the comments suggest, you can have a local and global version of angular cli on your system.
To be able to access your local version instead of global (lets say you have a different version installed locally then your global install) use npm run-script ng
for example
npm run-script ng generate component SomeCoolComponent

TL;DR
Use a package called npx (runnpm i -g npx
if not already installed) and when you need to create an angular project, just use this command the very first time:npx -p @angular/cli ng new hello-world-project
Explanation:
So For example if you want to create angular 4 project, modify the above command to include the angular-cli version 1.4.10 like this npx -p @angular/[email protected] ng new hello-world-project
and then when your project setup is complete you can go back to using the normal ng generate
and other commands.
Angular-cli versions indicate which angular version will be associated with a project & angular-cli 1.4.10 creates angular 4 projects
Edits:
Here is some useful versioning info about which cli creates which angular version.
CLI version Angular version
1.0 - 1.4.x ^4.0.0
1.5.x ^5.0.0
1.6.x - 1.7.x ^5.2.0
6.x ^6.0.0
7.x ^7.0.0
Also, if you want to use latest stable version to create a certain angular project you can just use npx command like this npx -p @angular/[email protected]
and it will use cli version 1.7.4 which is the most latest stable version for angular 5.
Check out this SO answer here where some other devs are trying to unfold this mystery.
Start your project by specifying the package -p @angular/cli
, so node can find the program:
npx -p @angular/cli ng new <project-name>
The npm ecosystem has been moving more and more towards installing tools as project-local devDependencies
, instead of requiring users to install them globally. This is considered a good practice. As it allows to use multiple versions (one per project), instead of having one unique global version.
In order to start the project from scratch, you need to point to the package with -p
flag (otherwise npx
will not find it):
npx -p @angular/cli ng new <project-name>
npx
is a command that is installed together with node
and npm
, starting version 5.2 (July 2017). Most probably you already have it installed.
npx
allows you to run that npm command without having it installed locally. npx
will look for the latest version of the specified package (in this case @angular/cli
) and run the command ng
from the bin folder.
You could also install a specific version of Angular CLI. For example, let's say we need to install version 9.1. We could run:
npx -p @angular/[email protected] ng new <project-name>
After the Angular CLI installs the project, go to the folder and use the npx ng
directly. For example:
npx ng serve
This will search inside the node_modules/.bin/
folder for the ng
command, which is a soft link pointing to ../@angular/cli/bin/ng
, the locally installed ng
command.
To install angular locally:
npm init -y
npm i @angular/cli
npx ng new app-name
To update a locally installed angular version, say bump 8.x to 9.x, you can use
npx ng update @angular/core@9 @angular/cli@9
