Hi,
I am on a project getting data from a PLC over OPCUA to a SQL Server. Therefor i wanted to use NodeRed. The RemotePC where i can connect to the OPCUA does not have an active internet connection. I already finished the installation of NodeRed offline. But now I really have a Problem to get the modules working.
I copied all the required node\_modules but i always get an Syntaxerror. Can anyone please help me.

Try downloading the tgz from npm then use the upload function in the palette manager.
Running `npm pack PACKAGE_NAME` on an internet connected device should download a tarball of the package.

Can you please explain how to download the tgz from npm? Never done this before?

I got the .tgz for contrib opcua, copied it to the offline PC, but there i got an installation error. Do I miss something?

copied?
did you not use the upload tgz feature?

i.e...
Also, did you remember to remove the other copied files you had added 👇

Yes. On the online PC I created the tgz.file. The I copied it to the offline RemotePC. There I first removed the copied modules for the opcua. Then I started there NodeRed and did the upload of the tgz. It started to install, but gives me an Error, because of no Internet Connection.
The Error i posted on the picture above, i only get on the offline PC. On the online device the contrib-opcua modules are working.

It may be trying to get dependencies.
You could also grab the dependencies of the contrib opcua node & install those using the command line then try upload the tgz again (hint, the dependencies are listed in contrib opcua's `package.json` file under `dependencies`)
Alternatively, you could try packing WITH dependencies using something like [@tar-erpedia/deep-pack](https://www.npmjs.com/package/@tar-erpedia/deep-pack)
Otherwise, you could start again & using try the [alternate-node-red-installer](https://github.com/TotallyInformation/alternate-node-red-installer) by Julian - you would install everything you need then copy all of the that to the offline PC.

The alternate installer is not really working for me. I tried the deep-pack, now i got a tgz-file for every dependency. How do i have to use them? Is there a special command to unpack them?

I followed the instruction you send me ([@tar-erpedia/deep-pack - npm](https://www.npmjs.com/package/@tar-erpedia/deep-pack)) So i installed npm i @tar-erpedia/deep-pack -g
On the Online device I typed in the following command "npm-deep-pack node-red-contrib-opcua"
The I got the following files, just every dependency as an tgz-file
