Unable to install since `npm` version 8.6.0

[fredden]

We've recently upgraded our 'node' docker image which brought an upgrade of npm (from version 8.1.2 to version 8.11.0). From what I can tell, there is a change that was introduced in npm version 8.6.0 which is not compatible with this module.

I've checked that I'm on the latest version of this package (tested with both version 1.12.0 and 1.12.2)

Steps to reproduce

1. Clone this repository (tested with 2a5854781c970044af38aabdce2efa1a6bf9e56e, which is tagged version 1.12.2)
2. Run docker run --rm -it -v $PWD:/app -w /app node:16 npm install

Expected result

Task completes successfully.

Actual result

At time of writing the 'node:16' image has npm version 8.11.0. When testing with version 8.5.5 this works, and from 8.6.0 this error shows. Works: docker run --rm -it -v $PWD:/app -w /app node:16 bash -c 'npm install -g npm@8.5.5 && npm install' Error as above: docker run --rm -it -v $PWD:/app -w /app node:16 bash -c 'npm install -g npm@8.6.0 && npm install'

We have the same problem, any updates?

We were able to work around this with npm install --legacy-peer-deps
