[angular] Installing a specific version of angular with angular cli

I searched through google and angular cli doc but couldn't find any way to install a specific version of angular using angular cli. is it even possible?

Yes, it's possible to install a specific version of Angular using npm:

npm install -g @angular/[email protected]

Next, you need to use the ng new command to create an Angular project based on the specific version you used when installing the CLI:

ng new your-project-name

This will generate a project based on Angular v8.3.19, the version which was specified when installing Angular CLI.

Use the following command to install and downgrade the specific version.
uninstall cli

npm uninstall -g @angular/cli

clean npm cache

 npm cache clean --force

install cli

npm install -g @angular/cli@_choose_your_version

Execute this command in the command prompt and you will be good to go

npm install -g @angular/cli@version_name

The angular/cli versions and their installed angular/compiler versions:

• 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

Can be confirmed by reviewing the angular/cli's package.json file in the repository newer repository. One would have to install the specific cli version to get the specific angular version:

npm -g install @angular/[email protected].* # For ^5.0.0

Edit #2 ( 7/2/2017)

If you install the angular cli right now, you'd probably have the new name of angular cli which is @angular/cli, so you need to uninstall it using

npm uninstall -g @angular/cli

and follow the code above. I'm still getting upvotes for this so I updated my answer for those who want to use the older version for some reasons.

Edit #1

If you really want to create a new project with previous version of Angular using the cli, try to downgrade the angular-cli before the final release. Something like:

npm uninstall -g angular-cli
npm cache clean
npm install -g [email protected]

Initial

You can change the version of the angular in the package.json . I'm guessing you want to use older version of angular but I suggest you use the latest version. Using:

ng new app-name

will always use the latest version of angular.

If you still have problems and are using nvm make sure to set the nvm node environment.

To select the latest version installed. To see versions use nvm list.

nvm use node
sudo npm remove -g @angular/cli
sudo npm install -g @angular/cli

Or to install a specific version use:

sudo npm install -g @angular/[email protected]

If you dir permission errors use:

sudo npm install -g @angular/[email protected] --unsafe-perm

Specify the version you want in the 'dependencies' section of your package.json, then from your root project folder in the console/terminal run this:

npm install

For example, the following will specifically install v4.3.4

"dependencies": {
    "@angular/common": "4.3.4",
    "@angular/compiler": "4.3.4",
    "@angular/core": "4.3.4",
    "@angular/forms": "4.3.4",
    "@angular/http": "4.3.4",
    "@angular/platform-browser": "4.3.4",
    "@angular/platform-browser-dynamic": "4.3.4",
    "@angular/router": "4.3.4",
  }

You can also add the following modifiers to the version number to vary how specific you need the version to be:

caret ^

Updates you to the most recent major version, as specified by the first number:

^4.3.0

will load the latest 4.x.x release, but will not load 5.x.x

tilde ~

Update you to the most recent minor version, as specified by the second number:

~4.3.0

will load the latest 4.3.x release, but will not load 4.4.x

npx @angular/cli@10 new my-poject

you can replace 10 with your version of choice... no need to uninstall your existing CLI! Just learnt that now...

npm i -g @angular/[email protected]

x,y,z--> ur desired version number

I would suggest using NVM to keep different versions of node and npm and then install the compatible angular-cli

use the following command to install the specific version. say you want to install angular/cli version 1.6.8 then enter the following command :

sudo npm install -g @angular/[email protected]

this will install angular/cli version 1.6.8

To answer your question, let's assume that you are interested in a specific angular version and NOT in a specific angular-cli version (angular-cli is just a tool after all).

A reasonnable move is to keep your angular-cli version alligned with your angular version, otherwise you risk to stumble into incompatibilities issues. So getting the correct angular-cli version will lead you to getting the desired angular version.

From that assumption, your question is not about angular-cli, but about npm.

Here is the way to go:

[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 (--force flag might be required)

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/[email protected]

[STEP 2] Create a project

ng new you-app-name

The resulting white app will be created in the desired angular version.

NOTE: I have not found any page displaying the compatibility matrix of angular and angular-cli. So I guess the only way to know what angular-cli version should be installed is to try various versions, create a new project and checkout the package.json to see which angular version is used.

Hope it helps
