@vladkras,
We have tried this scenario with the latest version of NodeJS but could not observe this issue. Could you please test the scenario with the latest version and share the feedback? We are also trying to establish the environment for Node 12 and will share our feedback after testing it.
@ahsaniqbalsidiqui, it's pretty easy to reproduce:
$ docker run --rm -it node:12 bash
# npm install aspose.barcode
I have installed node:12 as suggested by you and then followed the rest of the steps mentioned here:
https://docs.aspose.com/barcode/java/aspose-barcode-for-node-js-via-java-installation/#linux
No issue is observed and aspose.barcode is installed successfully using command npm install aspose.barcode
For your reference, to install Oracle JDK I followed the steps mentioned below.
https://hirosht.medium.com/install-oracle-jdk-1-8-and-set-environment-variables-in-ubuntu-82443a7b789
For installing Python 3, I used the following command:
sudo apt install python 3.8
npm install aspose.barcodeis not working on Node 12installations fails with error
