Error: error:0308010C:digital envelope routines::unsupported

Updated to latest VSCode 1.80.1 and installed official Ionic plugin v1.45.5 on Windows 11 Version 21H2 (OS Build 22000.795)

Clicking on Ionic icon showed project options to create a New Angular Project.

I selected my-first-app for the “Build Your First App” tutorial

This completed successfully. When building the following error and output were generated:

[Ionic] Building…

npx ionic build && npx cap copy

Node.js v18.12.1

[ERROR] An error occurred while running subprocess ng.

Googling a solution resulted in suggestion to downgrade Node.js to earlier LTS version or to add NODE_OPTIONS environment variable to:


This does build successfully in CMD or bash shells but does not work in VSCode due to limitations of what values are allowed for NODE_OPTIONS environment variable.

So, while build does work outside of VSCode thls may be off-putting to new developers just trying out Ionic for the first time in VSCode.

Modifying the app template to work “out of the box” with latest versions of components may help adoption of IONIC.

Note that this isn’t actually an Ionic issue but one from Webpack.
