How to install angular-cli without internet

This would be a good solution for your case.

npm i @angular/cli -g --cache MY_CACHE_FOLDER --cache-min 999999999 --no-shrinkwrap

1. Install node by using the executable files downloaded from the official node website.
2. Install the @angular/cli globally on the on-line machine.
3. Check the C:\Users\Admin\AppData\Roaming folder.
4. Zip the npm and npm_cache folder.
5. Transfer the above zip file and node executable to the offline machine.
6. Create the new project in angular
7. zip the node_module folder inside the created project and transfer it to the offline machine.

----Offline Machine------

9. Install node from its executable
10. Unzip the npm and npm_cache folder and move it to the C:\Users\Admin\AppData\Roaming folder.
11. Run the following command to install the @angular/cli and its dependencies

npm i @angular/cli -g --cache MY_CACHE_FOLDER --cache-min 999999999 --no-shrinkwrap

12. Now create the new angular project. It will show some errors but don't worry.
13. Unzip and move the node_module folder inside the new project.
14. Now, you can work/run on the project as usual.

With that ZIP only you will not be able to achieve that.

Because within the bin folder, the ng still needs some dependencies.

In order to do that:

• Download the zip from the official repo: https://github.com/angular/angular-cli/archive/master.zip
• Unzip it and go into that folder
• Run npm install or yarn
• Zip the whole folder again

Now you'll be able to run the CLI on an offline computer if you share that zip by doing:
- Unzip the CLI folder with the node_modules in it
- /path/to/the/folder/bin/ng new my-project

BUT. As this computer is offline, you'll only be able to scaffold a new project without installing it's required dependencies.

Now, if you want to build a project on that offline computer, you'll need something more:

On the online computer:
- install @angular/cli yarn global add @angular/cli (or use your zip)
- create a new empty project while online: ng new base-project
(wait for yarn install or npm install to finish)
- zip the node_modules folder, the one within the new project
(as node_modules_backup.zip for ex, and brace yourself... It's going to take a long time I guess)

On the offline computer
- Share the ZIP from the new project (with USB for ex) - Create your project: /path/to/the/folder/bin/ng new my-project --skip-install
- Unzip the node_modules_backup.zip into the newly created project

Now running /path/to/the/folder/bin/ng serve should work.
