Cannot install with yarn in combination with NodeJS 9

[mavdhe]

When installing jest-axe with the command yarn add jest-axe -D on a NodeJS 9 system the following error appears:

error jest-axe@2.1.1: The engine "node" is incompatible with this module. Expected version "8.9.4".
error Found incompatible module

If i directly require a copy of the jest-axe/index.js file in my project then all is well. So removing/changing the engines/node variable in package.json might resolve this problem.

Thanks for raising this, will see if I can make the engines less strict!

Edit: In the meantime you can run yarn --ignore-engines

Released as 2.1.2 thanks @ofnof for raising and @connor-baer for fixing :)
