"npm install" of a . tgz without internet connection

Question

I downloaded using "npm pack" and got the Ionic-4.0.6.tgz, now on PC without internet connection I ran the command "npm install Ionic-4.0.6.tgz" and it asks for internet connection.

Is there any way to install fully offline?

According to the https://docs.npmjs.com/cli/install it is possible to use NPM with local packages, supported commands:

npm install (sem argumentos)
npm install [<@scope>/]<name>
npm install [<@scope>/]<name>@<tag>
npm install [<@scope>/]<name>@<version>
npm install [<@scope>/]<name>@<version range>
npm install <git-host>:<git-user>/<repo-name>
npm install <git repo url>
npm install <tarball file>
npm install <tarball url>
npm install <folder>

Your case should be npm install <tarball file>, the question is, whether he is asking for internet should be because of some dependency that package ionic-4.0.6, remember, ALL packages contain their own package.json, so it may be that a package to be installed depends on other packages.

Just for the record, ionic-4.0.6.tgz should be pointed out as absolute path or should go to the project root folder, for example:

./projeto
  ├─── ./packages.json
  ├─── ./ionic-4.0.6.tgz
  └─── ./node_modules

If so then navigate to the "project" folder (example only) with cd and then execute the command npm install ionic-4.0.6.tgz, now if the package is in another folder you should point to the absolute path, for example:

cd projeto
npm install c:\projetos\outro_projeto_de_onde_copiará_os_pacotes\ionic-4.0.6.tgz

Note that if you already have the "client" (line command) of Ionic, you don’t need to install things manually, just run one of these 3 commands:

1. Create an empty app (I usually use this one :) ):

   ionic start <nome do projeto> blank
   

2. Create an app with tabs:

   ionic start <nome do projeto> tabs
   

3. Create an app with sidemenu:

   ionic start <nome do projeto> sidemenu
   

Change <nome do projeto> by the name of the folder you want to name for the project

Because usually in the global installation of Ionic (if already installed) you already have all dependencies saved in a type of cache on your computer, that is, it is likely that you need internet for this.
