I would like to copy a project folder and install it globally in an offline machine.
The project folder will have a package.json file and all the modules already installed in node_module folder. How can I do it?
Npm link and npm install won't work (long timeout, trying to connect to the internet).
Thanks
Edit 1:
Tried npmbox, the instllation is super slow...I need to find something better...

I am a total Javascript newbie aiming to configure my Mac nicely for development.
NPM is installed.
I notice that folder node_modules exists in my Users/MyName directory.
I think this is a result of having either installed Node/NPM or specifically run npm install airtable the other day, which I did at the time in Users/MyName.
When I npm uninstall airtable, it removes airtable and its dependency folders from nodule_modules, leaving the following: #types and package-lock.json (hidden).
If I cd to new project-specific directory Users/MyName/Projects/Code/myusername/airtable-test and run npm install airtable from there, I expected the packages may get installed in that folder. However, again, they get installed up at Users/MyName/node_modules.
In both cases, .package-lock.json (non-hidden) and package.json are in Users/MyName, which seems messy to me. (I haven't done anything non-standard in install).
Is this the way things should be?
Attempts to solve:
I seem to read, including from questions on Stackoverflow, that storing modules at Users/MyName/node_modules is effectively storing them globally, accessible to any app, and such that projects don't have to get committed to server with all dependencies in tow - the idea being that, after you deploy your app, you then run npm install whilst in its folder, prompting it to install all dependencies.
Is this right? Should I be looking at storing all dependency modules in a project folder, or above and outside of it?
(If the answer to this question is opinion-based, I wasn't aware of that).
Here is what I believe is happening. You have your package.json in folder Users/MyName and you are running npm install in Users/MyName/Projects/Code/myusername/airtable-test. But the problem is you do not have package.json file in the folder Users/MyName/Projects/Code/myusername/airtable-test. So npm goes up in the directory to find the package.json and it found it in Users/MyName so it is installing the package there.
This is happening because the way npm identifies a project is by looking for package.json. If it does not find it in current directory than it assumes that you must be inside some sub directory of the project and start searching upwards in the folder hierarchy to find the package.json.
solution
Do npm init in the folder Users/MyName/Projects/Code/myusername/airtable-test. This will initialize the folder as a npm package (by creating package.json).
My development machine has no internet connection and I want to install gulp on my project:
npm install -g gulp
On my machine with internet connection I don't have right to install any piece of software (node or npm).
There is a way to download gulp package (like I do for nuget packages) and to install it to my project?
When installing npm modules globally, they are by default saved to
C:\Users\{User}\AppData\Roaming\npm
You need to download the modules and manually place them in that folder, and make sure that the path has been added to Path environment variable on your computer.
Since you are not able to download them through npm, simply go to the gulp github repository, and place the content of that repository in a folder named gulp, in the path above.
npm install -g gulp
in your project directory use
npm link gulp
this will create shortcut of gulp module in node_modules so that you don't have to download it, make sure to upvote.
I'm working on an offline network and want to install angular-cli using npm.
I have a zip file of angular-cli and using the latest node and npm version.
I'm using the command: npm install ./angular-cli-master to install angular-cli from the folder.
But I keep getting this error telling me I don't have an internet connection (which is ok).
So how can I install this angular-cli while offline using the zip I downloaded from Github?
Thanks for your help.
You simply copy the package and all dependencies in your node_modules folder, inside the project for local installation, or in the global folder (npm config get prefix to see where it is located) for a global installation.
The behavior of npm install is to check for the dependencies, and install them first. When it doesn't find them installed, nor the local file containing them, it tries to download them.
Since all of those steps fail (you don't have the dependency installed, it isn't available on the expected location, and it can't download it), the installation fails.
You can find the dependency list in the package.json of each module, but since it is recursive, it can take a long time to have everything set right if you do it manually, npm does it by recursion.
For you, the easiest way would be to create a new folder on the connected PC, and inside it npm install angular-cli, zip the folder and transfer it on the offline machine.
Jan 2016 - check out Addy Osmani's recommendations for offline installation of npm packages
May 2017 - as of npm 5, you can pass the --prefer-offline flag to npm install
yarn does this out of the box.
In 2019, I found none recommended approaches were applicable to an "air gapped" server with no internet access.
I found the only solution was to, on windows, using artillery.io as an example:
install the package on a machine with internet access, e.g local dev machine. npm install -g artillery
Browse to C:\Users\{username}\npm
zip up the \node_modules\artillery (e.g artillery.7z)
Copy the zip and the files artillery, artillery.cmd (at root of npm folder) to the server
Paste the two artillery, artillery.cmd to the root of the servers npm folder (C:\Users\{serverusername}\npm)
Extract the zip to C:\Users\{serverusername}\npm\node_modules
This is the complicated version for just one tool. If your local machine's npm folder is relatively light on tools, you could always just zip the whole npm folder and copy + extract it on the server.
I still think it's odd that npm insists on trying to connect to the registry even when using npm pack and npm install -g <tarfile>
Problem: I'd been in similar situation where I can't install the express.js and all other dependencies specifies by package.json on my local machine (offline) using npm due to unavailability of internet connectivity.
Solution: I've a solution that works on Windows(not so sure of other platforms) through which I installed express framework with all the dependencies I required for my project which include cookie-parser, jade, morgan etc.
Steps :
Install all the package(s) on a remote machine which has an internet access.
In my case I'm using Windows on both remote as well as local machines and my requirement was of installation of express.js on local machine . So I run below command on my remote machine to install express.js
C:\Users>npm install -g express-generator`
After installation of express.js I created an app on my remote machine using:
C:\Users\Name\Desktop>express Project`
C:\Users\Name\Desktop\Project>npm install -g =>to install all other dependencies globally*
Now browse to location where npm's global modules are stored, you can view the location by
C:\Users>npm config get prefix
Generally in Windows its
C:\Users\{Username}\AppData\Roaming\
Simply copy the npm and npm-cache folder of your remote machine.
And place both copied folders viz. npm and npm-cache into your local machine on same location thats
C:\Users\{Username}\AppData\Roaming\
the short answer, you can't. Most NPM packages such as #angular/cli need other dependencies and those need child dependencies which get installed when you run npm install
You can, however, install the cli when on the network and use it when offline.
You can find the npm install command documentation here: https://docs.npmjs.com/cli/install
I am not quite sure and unfortunately, I do not have the chance to test it myself right now, but I would try to either unzip the folder and remove the dot, like that:
npm install /angular-cli-master
(= installing a folder not a zip file)
or just add the zip file ending like that:
npm install ./angular-cli-master.tgz
(= installing a zip-file not a folder, file ending may be .zip or something else, though)
Was test success with node 18.x.x.
The following step guild how to install http-server package
On Online PC:
npm install -g http-server
After finish install, copy http server folder. (Usually locate at: C:\Users[UserName]\AppData\Roaming\npm\node_modules)
On offline PC:
Paste http-server folder. e.g. D:\http-server
npm install -g D:\http-server
Online computer:
npm install -g offline-npm
copy the npm-module to the offline computer and thats it !
Is that any difference npm install and just move whole module folders? In fact, I'm trying to deploy my node app to linux server, but there is some problem with npm install so I move my node_modules folder entirely to linux server, apparently no problem with it.
Is it possible to be troubled this way later?
npm install doesn't just copy code from the Internet to node_modules. The installation might also compile code for the platform.
So if you are copying from/to the same platform it should be OK. Though even then some modules might not work depending on the environments.
npm install read package.json and install all missing modules in node_modules folder. There is no problem if you just copied node_modules folder from your source.
But if you want to install any new module then use:
npm install package-name --save (or -g if you want to install globally) so that your package.json can track new modules.
I have nodejs installed on a MBP which runs OSX 10.9, I have installed as a package downloaded from the nodejs website. Then I have installed the MEAN stack following instructions on mean.io.
The commands are:
sudo npm install -g mean-cli
mean init yourNewApp
That works correctly
Now the real issue is when after my app is created I enter the dir using the terminal, and write gulp, and it thows me some errors that some mandatory modules are not found.
The modules are written in the package.json file that mean generated, and they are installed as global modules on ~/.npm
I browsed the folder and there are all the required packages folders, inside the folders there is a package.tgz file which has the code of the package and a package folder which holds a package.json file describing the package itself.
Now I don't understand why the packages are compressed and why if they are installed globaly can not be accessed from gulp on my project folder.
Thanks in advance.
If you install some global module then you better don't put it into the package.json of your app because when you run your app that's the first place where is going to search and if it is there your app is going to look at node_modules folder and if it is not there your app will crash.
My advice is try to install your modules inside your app, npm install your_module --save because your app is gonna be portable and with a simple npm install you will be able to install all your needed packages.
But if you still wanna install global packages you maybe wanna follow this rules:
If you’re installing something that you want to use in your program, using require('whatever'), then install it locally, at the root of your project.
If you’re installing something that you want to use in your shell, on the command line or something, install it globally, so that its binaries end up in your PATH environment variable.
If you have the time to read the link then you will see that there are exceptions and how to handle them.
